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

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

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.

Permanent Mold Casting

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.

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.


In the die casting process, molten metal is injected under pressure into a reusable mold or die. The die contains an impression of the casting 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 them. Once the liquid metal has cooled sufficiently, the mold or is opened and the metal casting can be removed and finished.

high pressure die casting

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

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.


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.What is Die casting

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 (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.

Die castingFigure 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.

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.

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.


Die casting component parts, decorative trim, and/or finished products offer many features, advantages and benefits to those who specify this manufacturing process.zinc Die Casting

  1. Die castings are produced at high rates of production. Little or no machining is required.
  2. 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.
  3. Die casting provide parts which are durable, dimensionally stable, and have the feel and appearance of quality.
  4. Die casting dies can produce thousands of identical castings within specified tolerances before additional tooling may be required.
  5. Zinc die castings can be easily plated or finished with a minimum of surface preparation.
  6. Die castings can be produced with surfaces simulating a wide variety of textures.
  7. Die-cast surfaces, as cast, are smoother than most other forms of casting.
  8. Holes in die castings can be cored and made to tap drill sizes.
  9. External threads on parts can be readily die cast.
  10. Die castings provide integral fastening elements, such as bosses and studs, which can result in assembly economies.
  11. Inserts of other metals and some non-metals can be die cast in place.
  12. Corrosion resistance of die casting alloys rates from good to high.
  13. 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.
  14. Die Casting process can produce aluminum 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.

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.
Compared with forgings, die castings can 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.
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.

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

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 to know more about gravity casting

Relying on gravity will take patience, although it will be needed for larger products.

Magnesium Die Casting

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

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.

Advantages of high pressure die casting

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.
