The 1st step is to prepare the die halves for casting by cleaning the faces of each die then applying lubrication or release agent.
Once the die has been prepared, the die halves are closed and clamped together with pressure applied from the die-cast machine.
The clamping force will depend upon the size of the machine but must be more than the opposing force trying to open the die during the casting process.
The injection phase:
The ingots are added to the furnace and kept molten at a set temperature according to the metal being used.
The molten metal is transferred to an injection chamber and injected into the closed die pressure ranging from 1000 to 20,000 psi.
The pressure is maintained while the metal solidifies.
The amount is injected into the die is known as the ‘shot’
The injection of metal into the die is very short, this ensures the metals do not start to solidify before the die is completely filled.
The cooling phase:
After the injection is complete, the molten metal needs to solidify before the die is opened.
The cooling time will depend upon the part geometry as well as the metal thermodynamic properties.
The wall thickness of the parts plays a big factor in the cooling time, the thicker the wall section the longer the cooling time required.
The ejection phase:
After the cooling time has elapsed, the two die halves can be opened.
An ejection mechanism then pushes the solidified casting out of the die.
The force of the ejection will be determined by the size of the part, bearing in mind, the part shrink during the cooling process and tends to stick to the die surface.
Once the part has been ejected, the die can be closed ready for the next injection cycle.
The trimming phase
During the cooling and solidification phase, the casting will solidify as a complete cast unit which includes the part, flash, and any runner system
This excess material must be trimmed off to leave just the main cast product.
Method of trimming includes trim tools, band saw are manually clipping.
Any trimmed metal is either scrapped or recycled if permitted.
Advantages of die casting:
Die casting is fast
Die casting can be produced in seconds each part and quantities of hundreds to thousands of metal parts each day.
Near net shape
Die casting are produced “near net shapes” no matter how complex the shape are how tight the tolerances are.
Lighter weights
Die casting are stronger because of the material surface skin not the thickness of materials so parts can weigh less with thinner casting wall thicknesses.
Die casting is versatile
Many more part shapes and sizes can be produced using the die casting manufacturing process.
Die casting are durable
Die castings parts are metal and have a long service life.
Die castings are inexpensive
Die castings are fast to produce and useless material. Die casting are typically less expensive than most other metal parts manufacturing processes.

Die casting is a manufacturing process for producing accurately dimension, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies. The process is often described as the shortest distance between raw material and finished product. The term, “die casting,” is also used to describe the finished part. The term “gravity die casting” refers to castings made in metal molds under a gravity head. It is known as permanent mold casting in the U.S.A. and Canada. What we call “die casting” here is known as “high pressure die casting” in Europe.
First, a steel mold capable of producing tens of thousands of castings in rapid succession must be made in at least two sections to permit removal of castings. These sections are mounted securely in a machine and are arranged so that one is stationary (fixed die half) while the other is moveable (injector die half). To begin the casting cycle, the two die halves are clamped tightly together by the die casting machine. Molten metal is injected into the die cavity where it solidifies quickly. The die halves are drawn apart and the casting is ejected. Die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting. The complete cycle of the die casting process is by far the fastest known for producing precise non-ferrous metal parts. This is in marked contrast to sand casting which requires a new sand mold for each casting. While the permanent mold process uses iron or steel molds instead of sand, it is considerably slower, and not as precise as die casting.
TYPES OF MACHINES FOR DIE CASTING
Regardless of the type of machine used, it is essential that die halves, cores and/or other moveable sections be securely locked in place during the casting cycle. Generally, the clamping force of the machine is governed by (a) the projected surface area of the casting (measured at the die parting line) and (b) the pressure used to inject metal into the die. Most machines use toggle type mechanisms actuated by hydraulic cylinders (sometimes air pressure) to achieve locking. Others use direct acting hydraulic pressure. Safety interlock systems are used to prevent the die from opening during the casting cycles. Die casting machines, large or small, very fundamentally only in the method used to inject molten metal into the die. These are classified and described as either hot or cold chamber die casting machines.
HOT CHAMBER MACHINES Hot chamber machines (Fig.1) are used primarily for zinc, and low melting point alloys which do not readily attack and erode metal pots, cylinders and plungers. Advanced technology and development of new, higher temperature materials have extended the use of this equipment for magnesium alloy die casting. Figure 1: Hot Chamber Machine. Diagram illustrates the plunger mechanism which is submerged in molten metal. Modern machines are hydraulically operated and equipped with automatic cycling controls and safety devices. In the hot chamber machine, the injection mechanism is immersed in molten metal in a furnace attached to the machine. As the plunger is raised, a port opens allowing molten metal to fill the cylinder. As the plunger moves downward sealing the port, it forces molten metal through the gooseneck and nozzle into the die. After the metal has solidified, the plunger is withdrawn, the die opens, and the resulting casting is ejected. Hot chamber machines are rapid in operation. Cycle times vary from less than one second for small components weighing less than one ounce to thirty seconds for a casting of several pounds. Dies are filled quickly (normally between five and forty milliseconds) and metal is injected at high pressures (1,500 to over 4,500 psi). Nevertheless, modern technology gives close control over these values, thus producing castings with fine detail, close tolerances and high strength.
COLD CHAMBER MACHINES
Cold chamber machines (Fig. 2) differ from hot chamber machines primarily in one respect; the injection plunger and cylinder are not submerged in molten metal. The molten metal is poured into a “cold chamber” through a port or pouring slot by a hand or automatic ladle. A hydraulically operated plunger, advancing forward, seals the port forcing the metal into the locked die at high pressures. Injection pressures range from 3,000 to over 10,000 psi for both aluminum and magnesium alloys, and from 6,000 to over 15,000 psi for copper base alloys.
Figure 2: Cold Chamber Machine. Diagram illustrates die, cold chamber and horizontal ram or plunger (in charging position). Die casting provides complex shapes within closer tolerances than many other mass production processes. In a cold chamber machine, more molten metal is poured into the chamber that is needed to fill the die cavity. This helps sustain sufficient pressure to pack the cavity solidly with casting alloy. Excess metal is ejected along with the casting and is part of the complete shot. Operation of a “cold chamber” machine is a little slower than a “hot chamber” machine because of the ladling operation. A cold chamber machine is used for high melting point die casting alloys because plunger and cylinder assemblies are less subject to attack since they are not submerged in molten metal. CASTING DIES AND THEIR CONSTRUCTION
Die casting dies (Fig. 3) are made of alloy tool steels in at least two sections called fixed die half and ejector die half. The fixed die half is mounted on the side toward the molten metal injection system. The ejector die half, to which the die casting adheres, and from which it is ejected when the die is opened, is mounted on the moveable platen of the machine.
The fixed die half of the die is designed to contain the sprue hole through which molten metal enters the die. The ejector half usually contains the runners (passageways) and gates (inlets) which route molten metal to the cavity (or cavities) of the die. The ejector half is also connected to an ejector box which houses the mechanism for ejecting the casting from the die. Ejection occurs when pins connected to the ejector plate move forward to force the casting from the cavity. This usually occurs as part of the opening stroke of the machine. Placement of ejector pins must be carefully arranged so force placed upon the casting during ejection will not cause deformation. Return pins attached to the ejector plate return this plate to its casting position as the die closes. Fixed and moveable cores are often used in dies. If fixed, the core axis must be parallel to the direction of die casting mold opening. If moveable, they are often attached to core slides. Should the side of a die casting design require a depression, the die can be made with one or more slides to obtain the desired result without affecting ejection of the casting from the die cavity. All moveable slides and cores must be carefully fitted, and have the ability to be securely locked into position during the casting cycle. Otherwise, molten metal could be forced into their slideways causing a disruption of operations. Although slides and cores add to the complexity and cost of die construction, they make it possible to produce die castings in a wide variety of configurations, and usually more economically than any other metalworking process. TYPES OF DIES
Dies are classified as: single cavity, multiple cavities, combination and unit dies (Figures 4-A to 4-D).
A single cavity die requires no explanation. Multiple cavity dies have several cavities which are all identical. If a die has cavities of different shapes, it’s called a combination or family die. A combination of die is used to produce several parts for an assembly. For simple parts, unit dies might be used to effect tooling and production economies. Several parts for an assembly, or for different customers, might be cast at the same time with unit dies. One or more unit dies are assembled in a common holder and connected by runners to a common opening or sprue hole. This permits simultaneous filling of all cavities.
ADVANTAGES OF DIE CASTING
Die casting component parts, decorative trim, and/or finished products offer many features, advantages and benefits to those who specify this manufacturing process.
Die castings are produced at high rates of production. Little or no machining is required.
Die castings can be produced with thinner walls than those obtainable by other casting methods … and much stronger than plastic injection moldings with the same dimensions.
Die casting provide parts which are durable, dimensionally stable, and have the feel and appearance of quality.
Die casting dies can produce thousands of identical castings within specified tolerances before additional tooling may be required.
Zinc die castings can be easily plated or finished with a minimum of surface preparation.
Die castings can be produced with surfaces simulating a wide variety of textures.
Die-cast surfaces, as cast, are smoother than most other forms of casting.
Holes in die castings can be cored and made to tap drill sizes.
External threads on parts can be readily die cast.
Die castings provide integral fastening elements, such as bosses and studs, which can result in assembly economies.
Inserts of other metals and some non-metals can be die cast in place.
Corrosion resistance of die casting alloys rates from good to high.
Die castings are monolithic. They combine many functions in one, complex shaped part. Because die castings do not consist of separate parts, welded or fastened together, the strength is that of the material, not that of threads or welds, etc.
Die Casting process can producealuminum die casting, magnesium die casing, zinc die casting, brass die casting , lead casting and so on, and all of those can be easily massive produced.
Die casting is an efficient, economical process which, when used to its maximum potential, replaces assemblies of a variety of parts produced by various manufacturing processes at significant savings in cost and labour. COMPARISONS WITH OTHER PRODUCTS
Plastics injection molding Parts
Compared with plastic injection molding Parts, die castings are the stronger, stiffer, more stable dimension, more heat resistant, and are far superior to plastics on a properties/cost basis. They help prevent radio frequency and electromagnetic emissions. For chrome plating, die castings are much superior to plastic. Die castings have a high degree of permanence under load when compared to plastics, are completely resistant to ultra-violet rays, weathering, and stress-cracking in the presence of various reagents. Manufacturing cycles for producing die castings are much faster than for plastic injection moldings. Plastics, however, may be cheaper on a unit volume basis, have colour inherent properties which tend to eliminate finishing, are temperature sensitive, and are good electrical insulators.
Sand castings
Compared with sand castings, die castings require much less machining; can be made with thinner walls; can have all or nearly all holes cored to size; can be held within much closer dimensional limits; are produced more rapidly in dies which make thousands of die castings without replacement; do not require new cores for each casting; are easily provided with inserts die cast in place; have smoother surfaces and involve much less labor cost per casting. Sand castings, on the other hand, can be made from ferrous metals and from many non-ferrous alloys not suitable for die casting. Shapes not producible by die casting are available in sand castings; maximum size can be greater; tooling cost is often less and small quantities can be produced more economically. you can check more sand aluminium casting
Permanent mold castings
Compared with permanent mold castings, die castings can be made to closer dimensional limits and with thinner sections; holes can be cored; are produced at higher rates with less manual labour; have smoother surfaces and usually cost less per die casting. Permanent mold casting involves somewhat lower tooling costs; can be made with sand cores yielding shapes not available in die casting. Forgings Compared with forgings, die castingscan be made more complex in shape and have shaped not forgeable; can have thinner sections; be held to closer dimensions and have coring not feasible in forgings. Forgings, however, are denser and stronger than die castings; have properties of wrought alloys; can be produced in ferrous and other metals and in sizes not suitable for die castings. Stamping Compared with stamping, one die casting can often replace several parts. Die castings frequently require fewer assembly operations; can be held within closer dimensional limits; can have almost any desired variation in section thickness; involve less waste in scrap; are producible in more complex shapes and can be made in shapes not producible in stamped forms. Stamping, on the other hand, have properties of wrought metals; can be made in steel and in alloys not suitable for die casting; in their simpler forms, are produced more rapidly; and may weigh less than die castings. Screw machine products Compared with screw machine products, die castings are often produced more rapidly; involve much less waste in scrap; can be made in shapes difficult or impossible to produce from the bar or tubular stock, and may require fewer operations. On the other hand, screw machine products can be made from steel and alloys which cannot be die cast; they have the properties of wrought metals, and they require less tooling expense.

High pressure die casting process
In this process, the liquid metal is injected at high speed and high pressure into a metal mold. A schematic view of high pressure die casting is given in Figure.
This equipment consists of two vertical plates on which bolsters are located which hold the die halves. One plate is fixed and the other can move so that the die can be opened and closed. A measured amount of metal is poured into the shot sleeve and then introduced into the mould cavity using a hydraulically-driven piston. Once the metal has solidified, the die is opened and the casting removed. Compared to Gravity die casting, both the machine and its dies are very expensive, and for this reason, high pressure die casting is economical only for high-volume production.

Different Between Aluminum Die Casting and Gravity Casting
Aluminium Die Casting is more than just an excuse to play with the molten metal it is actually a great way to create art and complicated pieces of machinery or other items that would otherwise be nearly impossible to make. Aluminum die Casting is really a great way to save money…while playing with molten metal.
The reason that aluminum die Casting has survived the test of time is a matter of efficiency. Some of the earliest casting examples have been found in China dating back thousands and thousands of years. In fact, every major civilization from the Egyptians to the Romans practised aluminum casting. This skill came back into vogue during the Renaissance and has continued to advance and evolve from there. While Sand Casting is the most popular casting process there are many, many more processes available to the backyard foundries.
Not everyone is going to be casting heavy pieces like engine parts or cast their own motorcycles. So for those that just want to make decorative pieces, you will not be using the same casting process as these heavy duty casters. For artists creating small scale statues or embellishes and for hobbyists that need a decorative touch to their model plane or boat might want to consider using gravity casting for their needs.
What is Gravity Casting
Gravity Casting seems to be especially useful when dealing with aluminum and other light alloys. The basic idea behind this casting process is pretty much exactly what the name suggests. The metal is introduced into the mold by the force of gravity. Most other casting process either use natural pressure difference like the kind in certain sand casting procedures or they use forced pressure like in centrifugal casting to get the molten metal into the mold.
One of the most common uses for gravity casting is when permanent molds are going to be used. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level. While some temporary molds can be repeatedly used the quality of the finished product will begin to suffer over time. With die molds the quality will remain the same. Die molds should be seen as an investment. Yes, they will be more costly than other molds; however, they will outlast cheaper options for molds. With Permanent molds, they are created using cast iron, steel, and other metals.
Gravity casting is used for the permanent mold process with pleasing results. Gravity casting is usually used when the finished product is more visually based then structurally based which is why this method is a favourite of artists and even some jewellers. The loss of strength is due to the lack of pressure used in this process. For those that need the strength but still want to use gravity casting, more of the molten metal will need to be used which will increase the weight. go to https://www.aludiecasting.com/ to know more about gravity casting
Relying on gravity will take patience, although it will be needed for larger products.

Casting is a process in which molten metal is poured into a mould that contains the intended shape. High pressure die casting (HPDC) is the most common method of Magnesium Die Casting and its alloys.
Magnesium is melted at a temperature of 923K and poured into crucibles where it is cooled under high pressure. The cooled magnesium solidifies and takes the shape of the crucible.
Magnesium has an inflexible hexagonal structure at its basic atomic level which makes it difficult to roll, stretch and shape. HPDC overcomes this limitation by offering an alternative, less difficult and faster method for manipulating Magnesium.
Uses of Magnesium die casting
Magnesium is increasingly used in automotive and airplane manufacturers. This is due to its lightweight per unit volume. Casted Magnesium is also used in the manufacture of lightweight car seats, car bodies, and fuselage parts. The use is attributed to Magnesium is the lightest structural metal which can withstand greater column loading per unit weight.
Magnesium and its alloys are being used to manufacture chassis for appliances such as laptops, cameras, and phones.
Magnesium castings are also used in the manufacture of power tools such as chain saws, electric drills, and electric nail guns. The use of electrical appliances is gaining ground owing to its ability to conduct heat and electricity.
Magnesium casting offers good finishing characteristics as minute details can be impressed onto the final product. High pressure dies casting is more economical compared to other methods of shaping Magnesium.
In this green era, the ability to recycle Magnesium makes High pressure die casting an environmentally friendly process. Magnesium metal is almost 100% recyclable thus reduces industrial junk.
Casted Magnesium alloys have high conductivity. There is marked improvement in the electrical and thermal conduction capabilities in Magnesium alloys making them suitable for use in electrical and thermal appliances.
Magnesium and its alloys can be cast into various shapes suited for different uses; Casting into thin walls can be achieved. Since Magnesium saves on weight without reducing durability, Magnesium thin walls are relatively stronger and lighter as compared to other metals of the same volume.
It has been noted that molten Magnesium has reduced affinity to iron thus can be cast in iron crucibles with a reduced risk in the final product acquiring iron impurities.
Casted Magnesium is resistant to corrosion by the elements, most notably, is the reduced susceptibility to Hydrogen porosity.
Disadvantages of high pressure die casting
Due to its very high melting point, melting Magnesium is both dangerous in safety and expensive process. A lot of energy is required to melt the Magnesium thus increasing the cost of production.
Moreover, the very high molten temperature of Magnesium can cause the liquid metal to take some of the iron from the crucible. Acquiring iron from the crucible is often undesirable as it would make the final product relatively impure.
Molten Magnesium is more viscous than other metals such as Aluminum. As a result, more pressure is required in the cooling process in an attempt to acquire the intended casting detail since cooling is often done under pressure.
To produce Magnesium die casting has high risk than producing Aluminium die casting, Magnesium is easy to get on fire since the ignition point is very low and it is hard to control this. this is why the cost is more expensive than Aluminum die casting. contact us to know more info.

The die casting process is very important and pros always make sure to use all the necessary things, called- furnace, metal, die casting machine, die and other various materials. The metal which is used here is always non-ferrous alloy, like- Zinc and aluminum, later it is melted in the furnace and then injected into the dies in the die casting machine for producing very complex metal parts.
It is always better to approach the right company for aluminum casting parts as they always go with the best and authentic procedures in order to produce something the best. They may use different types of die casting machines, called – hot chamber machines and cold chamber machines for a perfect die casting solution. Hot chamber machines are used for those alloys which have low melting temperatures, such as zinc. And Cold chamber machines are used for those alloys with high melting temperatures, such as aluminum. Both machines work the same and once they are done with the molten metal, they inject the same into the dies, wait for cooling it down and solidify into the final part, called the casting.
Aluminum die casting tooling is also known as dies, is here just for alloying the steel. The dies are finished from at least two sections to allow casting elimination. To do so, there is a special need of the efficient approach of die casting and some go with the portable slides, with certain sections that can be done without difficulty to build the ideal shape as demanded by clients from die casters. In the procedure, die casting tooling goes with the simple production of the holes through the predetermined die half. Once we have the molten metal, it is then dispensed into the hole in order to dry in the cavity and this is the best way to get the specific dimensions contoured in the plating. Dies may also have to lock pins, which are utilized in order to stick together two halves and to take away the cast part. Always find the best and reliable service provider for aluminum die casting as well as who can easily manufacture miniature to large precision components using the broad range ofzinc die casting, aluminum and magnesium die casting alloys.
It is important to know that each and every alloy has unique physical characteristics to match your specific application.

Aluminum Die Casting: The Technology Behind High-Quality Industrial Parts
Aluminum die casting is a highly popular manufacturing technology, widely used in the production of high-quality industrial parts. This process is based on injecting liquid aluminum alloy into a die casting mould, which then cools and solidifies, forming the desired shape and design.
In this page, we’ll explore the manufacturing process of aluminum die casting, its advantages, applications, limitations, and future development.
The Manufacturing Process of Aluminum Die Casting
Aluminum die casting process is made by a professional aluminum die casting manufacturer, who use die casting molding process where molten aluminum alloy is injected into a steel mold or die, under high pressure, to produce a complex and intricate shape. The molten metal is forced into the mold cavity, where it cools and hardens, forming a solid part. The die casting mold is typically made of two halves that are clamped together during the process using a hydraulic system.
The aluminum die casting molding process involves several steps, including die casting mold preparation, melting the aluminum alloy, injection of the molten metal into the mold cavity, cooling and solidification of the metal, and ejection of the finished part from the mold.
Die Casting Mold Production
The die casting mold preparation involves designing the shape and size of the part using computer-aided design (CAD) software. The mold and its components are then manufactured using computer-controlled lathes or CNC machines. The mold is made of high-quality steel that can withstand the high temperatures and pressures of the process.

How to make aluminum alloy die casting tooling?
Aluminum alloy die casting tooling, also known as the die or mold, is an essential component of the die casting process. To make aluminum alloy die casting tooling, you can follow these steps:
Design the tooling: Aluminum die casting manufacturer will Create a 3D design of the tooling using computer-aided design (CAD) software. The design should be based on the specifications of the part you want to produce, so ensure that the measurements and features are correct.
Select the tooling material: The aluminum die casting manufacturer will choose the tooling material, the most common materials used for die casting tooling include steel, H13 steel, 8407 or aluminum. Steel is durable and can withstand high temperatures; H13 and 8407 steel are premium quality steel that offers the highest quality output, while aluminum is cost-effective for light-duty applications.
Create the tooling cavity: aluminum die casting manufacturer will machine the tooling cavity from the selected material using a CNC machine based on the design. The cavity should be precise, and it should have a proper grain structure for optimal part quality.
Add cooling system: Incorporate appropriate cooling systems, using customized drilling procedures, into the die to control the temperature and maintain high-quality output.
Finalize the tooling: Align the die half, and integrate additional necessary components such as ejector pins, moving chokes, and runner bars as needed. Then, both halves of the tooling are fixed together.
Test and verify: Finally, after the tooling is made, aluminum die casting manufacturer will test it to ensure that it operates correctly, and there are no defects in the parts produced.
By following these steps, aluminum die casting manufacturer can create durable and high-quality aluminum alloy die casting tooling. With proper usage and maintenance, the tooling can last for years, and it can produce consistent and precise parts.
Melting of Aluminum Alloy
Once die casting mold is ready, then move the mold into die casting molding machine to make aluminum die casting parts. The aluminum alloy is melted in a furnace and heated to a specific temperature. The alloy composition can vary, depending on the desired mechanical and physical properties of the finished part.

How to make aluminum die casting prototypes?
Aluminum die casting prototypes can be made by following these steps:
Design the part: The first step is to create a 3D design of the part using computer-aided design (CAD) software. This design will be used to create the mold for the die casting process.
Create the mold: Once the design is complete, a mold must be created. This can be done using a CNC machine to create the mold out of steel or aluminum.
Select the appropriate aluminum alloy: Different aluminum alloys have different properties. Select the appropriate alloy based on the properties needed for the specific prototype.
Prepare the furnace: Prepare the furnace and fill it with the selected aluminum alloy. Heat it to the optimal temperature, which will vary depending on the alloy used.
Inject the metal: Once the temperature has been reached, the molten metal is injected into the mold cavity under high pressure. The high pressure helps to ensure that the metal is distributed evenly and accurately within the mold.
Cool and eject the part: After the metal has been injected into the mold, it is allowed to cool and harden. Once it has cooled and hardened, the part is ejected from the mold.
Finish the prototype: After the part is ejected from the mold, any additional finishing or machining can be done as needed to create a fully functional prototype.
The process of creating an aluminum die cast prototype is similar to the process used for creating a full production run. The main difference is that a more basic mold is used for the prototype, allowing for a much quicker turnaround time.
