Die casting is a metal casting process which is characterized by pressing molten metal into the mold cavity. The mold cavity is made using two hardened tool steel molds that are worked on during processing and work similarly to injection molds. Most die-casting is made from non-ferrous metals, especially zinc, copper, aluminum, magnesium, tin, lead, and tin-based alloys. Depending on the type of metal being thrown, a thermal or cold engine is used.
Zinc die casting
The zinc die casting process is very popular for making parts in building and industrial fields, but the most common application is in the automotive industry. In fact, cars have different parts that can be made through die casting, in such a way that the modern process of die casting was originally started for the automotive industry.
With the casting process often no further machining is needed after casting: not only is the accuracy up to 99.8%, but the casted products can also be used raw because they have a pleasant finish. The use of zinc die casting is almost 28% in the automotive industry, followed by the building and hardware sector.
Zinc has become one of the most important metals in the auto parts industry, especially for products such as door lock housing, pawl, gears and retractor pulleys in seat belt systems, but also for camshaft and sensor components. By using this metal and its alloys, it is possible to achieve strength, ductility, and flexibility that would not be possible with other materials.
In addition, zinc can be the right choice to get high-quality aesthetic components, with tight tolerances that are not possible with other materials, and to get embossing and grooves for mechanical components or gears.
Zinc Die Casting Mechanisms in Automotive
As said before, the automotive industry is the most common die casting application: using zinc and its alloys makes it possible to produce components that are able to achieve high aesthetic quality, with tight and narrow tolerance for shape morphology. Zinc alloys are also used for coatings because of its many benefits, such as improving the anti-corrosion properties of zinc which are already impressive.

This process has evolved over the years, from low-pressure injection molds to casting molds at pressures of up to 4,500 psi. The process can create high-quality products with excellent end surfaces.
Die Casting is an economical and efficient process for making various shapes. Considered superior to other manufacturing techniques, it is durable and aesthetic and combines perfectly with other parts of the machine that are part thereof. Dying has many advantages. Among these, the main is its ability to produce complex forms with a higher tolerance level than other mass-production methods. Thousands of identical prints can be produced before you need to add new mold tools.
Zinc die casting
High Die-pressure is a manufacturing process where aluminum that has been melted is injected by a casting machine under extreme pressure on steel or molds to make the design and detail parts of the model you want to make. Casting in tons of universal tightening. This record reflects the amount of pressure given on the matrix. The engine size varies from 400 to 4000 tons.
There are many advantages to using the die casting process compared to others. Die casting produces parts with thinner walls, narrower size limits and processes can be accelerated. Labor costs and finishing are the lowest with the dice. This process facilitates to obtain intricate forms with narrower tolerances. Unlike the forgery process, you can insert the kernel into the product created by this process.
Forms that cannot be obtained from rods or tubes can be easily achieved with casting. The number of operational processes is smaller, which leads to the reduction of waste materials.
Die casting is used when you need a stable, dimensional and durable component. They withstand heat and maintain a good level of tolerance, an important condition for each part of a good machine. They are stronger and lighter than the part made by other printing methods. Its parts are not welded or screwed, which greatly increases its efficiency.

Zinc die casting Parts is referred to as the hot-chamber process. It is the method by which zinc (zamak) is heated under high temperatures and the molten material forced into a zinc die casting mold under high pressure to produce product with a similar shape as the die. As the metal moves through the die, air escapes through the vents. Once the die is full, the high pressure is maintained until it solidifies and the die is separated to release the finished zinc cast. After casting, no further modification is usually required.
Zinc (zamak) is known for its high strength, accuracy, ductility, ease of casting, high thermal and electrical conductivity, and long life. As such, the zinc die casting is applied in the manufacture of high quality industrial and building materials. Die casting started in the automotive industry and it is still widely used in the manufacture of automotive components. The door locks casing, pulley, and the camshaft are some of the car parts that are made of zinc casting. In the construction industry, zinc die casting is utilized in the manufacture of components such as door knobs, faucets, and roofing. On the other hand, there are many zinc casting machine parts, such as electrical fittings.
Zinc Die Casting Process
Zinc is cast using the hot-chamber process due to its low melting temperatures. Cold chamber process is applied in the casting of metals with high melting temperatures such as the aluminium. The zinc die casting process involves the preparation of the metal, die preparation, and finishing. It commences with the preparation of the die followed by the metal. Notably, the die can be used once or severally depending on the component being manufactured. If it was used before, it should be lubricated to ease the removal of the cast metal. Afterwards, the ejector die half and the cover die half are screwed. The cover die half has a sprue through which the molten metal is injected while the ejector die has ejector pins for removing the castings.
Preparation of the die is followed by melting of the ZA or the ZAMALAK alloy on a furnace. The physical properties of the product dictates the choice of the alloy. Due to metal hardness and strength, the furnace temperature is usually very high. The oxidized parts of the metal are removed at this stage to raise the purity of the finished product. Various chemicals can be added to improve physical properties of the finished alloy.
Once the molten metal is prepared, it is injected into the feed system under high pressure. Most of the systems have several dies for efficiency and mass production. The raised pressure ensures that the molten zinc alloy gets into the mold as fast as possible, no air gets into the molten metal, and the expulsion of the air in the die through the vents. After filling the die, the pressure is raised further until the zinc alloy casting solidifies. The process also involves cooling using water. Then, the two dies are separated and the metal cast is removed. This is followed by the cleaning of the feed system to get rid of the flash. Further finishing can be carried out depending with the final use of the product. The runner that is removed from the final product and the flash are usually recycled.

Metal casting services involve the shaping of free-flowing liquid metals through the use of dies, molds, or patterns. Castings are generally roughly finished due to the nature of their production. In many cases, additional finishing is required to remove burrs and other artefacts of the casting process. Metal castings services are used to design a wide range of components and finished products. Everything from simple nails and fasteners to engine blocks can be fabricated using metal casting services. Common metal casting processes include sand casting, die casting, permanent mold casting, investment casting, centrifugal casting, and lost foam casting.
Sand casting is used to make large parts (typically iron, but also bronze, brass, aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). Sand castings generally have a rough surface, sometimes with surface impurities and surface variations.
zinc Die Casting
Die-casting includes a number of processes in which reusable dies or molds are used to produce casting. The die contains an impression of the finished product together with it’s running, feeding and venting systems. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold is opened and the casting can be removed and finished.
In permanent mold casting, molten metal is poured into cast iron molds, coated with a ceramic mold wash. Cores can be a metal, sand, sand shell, or other materials. When completed, the molds are opened and the castings are ejected.
Investment casting services involve molding patterns by the injection of a special wax into a metal die. The patterns are assembled into a cluster around a wax runner system. The ‘tree’ of patterns is then coated with 8-10 layers of refractory material. The assembly is heated to remove the wax. The hot mold is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high-pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system.
Centrifugal casting
Centrifugal casting services are used to produce castings that are cylindrical in shape. In centrifugal casting, a permanent mold is rotated about its axis at high speeds as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies. The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical need with pipes. The inside diameter has more impurities and inclusions, which can be machined away.
magnesium die casting
Lost foam casting
Lost foam casting (LFC) is metal casting services that use foam filled patterns to produce castings. Foam is injected into a pattern, filling all areas, leaving no cavities. When molten metal is injected into the pattern, the foam is burned off allowing the casting to take shape.
Die casting
Die casting and metal casting includes a number of processes in which reusable dies or molds are used to produce casting. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold or is opened and the casting can be removed and finished.

The high pressure die casting process is the most widely used, representing about 50% of all light alloy casting production. Low pressure die casting currently accounts for about 20% of production and its use is increasing. Gravity die casting accounts for the rest, with the exception of a small but growing contribution from the recently introduced vacuum die casting and squeeze casting process. the design of low pressure and gravity die casting dies for improved die filling, optimized solidification pattern and maximum yield. Gravity die-casting is suitable for mass production and for fully mechanized casting. Low-pressure die casting is especially suited to

the production of components that are symmetric about an axis of rotation. Light automotive wheels are normally manufactured by this technique.
Die casting metals can vary widely, and different die casting companies may have the ability to work with anyone or number of them. Some of the most common metal casting types include aluminum die casting, brass die casting, lead die casting (the most popular for model die casting), magnesium die casting, and zinc die casting.

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.
