A wide range of industries can benefit from die casting due to its efficient way of manufacturing complex components and parts. Die casting allows you the ability to manufacture a wide range of components, with efficiency and precision.
Common die casting methods include high pressure die casting (HPDC) and low pressure die casting (LPDC). Factors to consider when deciding which die casting process is best for your needs includes component complexity as well as casting cycle speeds.
High Pressure Die Casting
High pressure die casting occurs when molten metal is injected/forced into a mold or die. The molten metal is injected horizontally. Advantages of high pressure die casting include:
- Speed. Shorter casting cycle than LPDC
- Ideal for thin-walled designs
- Smooth surface finishes
- Cost-efficient for high-production runs
- Works well for large alloy components
HDPC works with both hot chamber and cold chamber die casting.
Low Pressure Die Casting
Low pressure die casting occurs when molten metal is slowly filled into the die cavity via a tube in a holding furnace. As opposed to HPDC, LPDC is filled vertically into the mold. Advantages of low pressure die casting include:
- Precision and high dimensional accuracy
- Well suited for designs with a substantial wall thickness
- Exceptional strength values
- Ideal for complex geometries and designs
- Well suited for automation
- Cost-effective for small production runs
Common HPDC and LPDC Die Cast Metals
Aluminum, magnesium, and zinc are often used for die cast components and parts.
Aluminum Die Cast Components
Benefits of aluminum die cast components
