Custom robot aluminum alloy die casting metal casting
For high-volume production of comparatively complex metal parts, die casting is the most suitable manufacturing process. Die cast parts are manufactured using steel moulds that resemble those utilized in injection moulding. Instead of plastics as used in injection moulding, die casting involves metals with low melting points such as zinc and aluminium. Die casting is a popular option due to its accuracy, reliability, repeatability, and versatility.
In the die casting process, high pneumatic pressure or hydraulic pressure forces molten metal into a steel mould or die. These moulds and dies can produce metal parts with complex geometries. The die casting process produces most of the metal parts involved in all casting processes.
Die casting companies typically specialize in casting either magnesium, zinc or aluminium. Aluminium makes up approximately 80% of die cast parts.
Advantages of Die Casting Process
Die casting stands as a significant technique in metal fabrication, esteemed for its cost-effectiveness and user-friendly nature.
The advantages it brings:

The Benefits Of Aluminium Die Casting Services:
Castings manufacturer components provide EMI/RFI shielding, rigidity, and durability with minimal weight.
Due to aluminum’s electrical performance and shielding property benefits, die cast aluminum is ideal for electronic connectors and housings.
Aluminum die cast parts are very lightweight and can withstand very high operating temperatures.
Common die casting aluminum alloys include:
|
380: A general-purpose aluminum alloy which balances castability with good mechanical properties. It is used in a very wide variety of products, including engine brackets, furniture, electronics enclosures, frames, handles, gearbox cases, and power tools.
|
|
390: An alloy with excellent wear resistance and vibration resistance. It was developed specifically for the die casting of automotive engine blocks and is also suitable for valve bodies, impellers, and pump housings.
|
|
413: An aluminum alloy with excellent casting properties. It has good pressure tightness and is therefore used for products like hydraulic cylinders, as well as architectural parts and food and dairy industry equipment.
|
|
443: The most ductile of die casting aluminum alloys, this alloy is suitable for consumer goods, especially those that require plastic deformation after casting.
|
|
518: A ductile aluminum alloy with good corrosion resistance. It is used in a variety of products, including aircraft hardware fittings, ornamental hardware, and escalator components.

Types Of Die Casting Processes
In the industrial realm, two main methods for die casting are the hot chamber and cold chamber processes.
Below, we outline the details of these two processes.
|
Hot-chamber die casting
| |
 |
Hot-chamber die casting utilizes a molten metal reservoir to fill intricate molds quickly, making it ideal for low-melting point alloys like zinc and tin.
|
|
Cold Chamber Die Casting
| |
|
Cold chamber die casting is excellent for handling high melting point materials like aluminum, preventing damage to the pumping system caused by extreme temperatures. In this method, molten material is poured into a cold chamber before being injected into the die, utilizing a hydraulic system similar to hot chamber casting.
|
Surface Finish
Surface finishing is crucial in die casting to enhance product aesthetics and functionality, ensuring parts meet precise specifications and
provide optimal performance.

| Powder Coating
| Ceramic Coating
|
| |
| Anodizing
| Plating

Die Casting Process
Whether it's hot or cold chamber die casting, the standard procedure involves injecting molten metal into a die mold using high pressure.
Here are the detailed steps in the die casting process:
|
| l Clamping At the outset, clean the die to eliminate impurities and apply lubrication for smoother injection and product removal. Once cleaned and lubricated, firmly close the die with high pressure.
|
| l Injection Melt the chosen metal and pour it into the shot chamber. The method differs based on the process being used. | |
| l Cooling While the die is closed, allow the metal to cool and solidify. The resulting solid material will take on the shape of the mold design.
| |
| l Ejection After unclamping the die mold, an ejection mechanism will push the solid casting out of the mold. Make sure the product has fully solidified before ejecting.
| |
| l Trimming This marks the final step, involving the removal of excess metal from the sprue and runner on the finished product. Trimming can be done using a trim die, saw |
