Aluminum Die Casting
Aluminum - This alloy is lightweight, while possessing high dimensional stability for complex shapes and thin walls. Aluminum has good corrosion resistance and mechanical properties, high thermal and electrical conductivity, as well as strength at high temperatures.
Aluminum die casting is a process where molten aluminum alloy is injected into a casting die under high pressure and at a controlled temperature. The mold has two sections, the "cover" half and the "ejector" half. The die may also have additional moveable segments called slides or pulls, which are used to create features such as undercuts or holes, which are parallel to the parting line.
Aluminum die castings dies are run in cold chamber die casting machines. These machines are operated at the required temperatures and pressures to produce a quality part to net-shape or near net-shape specifications. Aluminum die castings can be readily machined, anodized, painted, powder coated or even chrome plated.
Because of its superior mechanical properties, aluminum die castings are among the highest volume, mass produced items manufactured by the metalworking industry today.
Aluminum die castings are important components of products like automobiles, computers, washers, dryers, refrigerators, furnaces and even toys. Some parts can be as simple as a faucet handle or as complex as a transmission housing.
Wilkast Aluminum Alloys Offered
Alloy A380 is the most common of the aluminum die casting alloys. It offers the best combination of casting and product properties. It is used for a wide variety of products such as garden equipment, chassis for electronic equipment, engine brackets, housings for automotive alternators, starters and water pumps, home appliances, furniture, office equipment hand tools and power tools.
Alloy A360 offers high corrosion resistance and superior strength at elevated temperatures than 380. Other properties are essentially equivalent.
