Product Description and Process

High Pressure and Low Pressure Aluminum Die Casting Process Foundry

Production process: aluminum die casting process

Machining process: CNC machine, machining center, lathe, mill machine, drill machine, etc.

Surface treatment process: anodic oxidation, Dacromet coating, etc.


Product Material and Uses

Normally produce with JIS ADC1, ADC3, ADC5, ADC6, ADC10, ADC12, ASTM A413, A360, A380, A383, etc.

The aluminum casting products are widely used for electronic industry, auto-car parts, electric motor parts, aero craft parts, watercraft parts, medical treatment equipment, communication system, other machinery components, etc.


Cast Material of Die Casting

The main die casting alloys are: zinc, aluminum, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is also possible. Specific die casting alloys include: Zamak; zinc aluminum; aluminum to, e.g. The Aluminum Association (AA) standards: AA 380, AA 384, AA 386, AA 390; and AZ91D magnesium.


The following is a summary of the advantages of each alloy:

Zinc: the easiest metal to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life.

Aluminum: lightweight; high dimensional stability for complex shapes and thin walls; good corrosion resistance; good mechanical properties; high thermal and electrical conductivity; retains strength at high temperatures.

Magnesium: the easiest metal to machine; excellent strength-to-weight ratio; lightest alloy commonly die cast.

Copper: high hardness; high corrosion resistance; highest mechanical properties of alloys die cast; excellent wear resistance; excellent dimensional stability; strength approaching that of steel parts.

Silicon tombac: high-strength alloy made of copper, zinc and silicon. Often used as an alternative for investment casted steel parts.

Lead and tin: high density; extremely close dimensional accuracy; used for special forms of corrosion resistance. Such alloys are not used in foodservice applications for public health reasons. Type metal, an alloy of lead, tin and antimony (with sometimes traces of copper) is used for casting hand-set type in letterpress printing and hot foil blocking.

Traditionally cast in hand jerk molds now predominantly die cast after the industrialization of the type foundries. Around 1900 the slug casting machines came onto the market and added further automation, with sometimes dozens of casting machines at one newspaper office.

Maximum weight limits for aluminum, brass, magnesium and zinc castings are approximately 70 pounds (32 kg), 10 lb (4.5 kg), 44 lb (20 kg), and 75 lb (34 kg), respectively.

The material used defines the minimum section thickness and minimum draft required for a casting as outlined in the table below. The thickest section should be less than 13 mm (0.5 in), but can be greater.
