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:
- Accomplish intricate part designs
- Reduce labor expenditures
- Attain varying wall thicknesses
- Achieve stricter tolerances
Disadvantages of Die Casting Process
- Incompatible with metals boasting elevated melting points
- Incompatible with extensive sheet metal components
- Substantial die expenses
- Extended lead times

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.

| 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 |
