Die Casting

The die casting is suitable for applications that require good surface finish and dimensional consistency. The main die casting alloys are: zinc, aluminium, copper, magnesium, lead, and tin etc. Manufacture of parts using die casting is relatively simple, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium sized castings.
Applications:
We can make die casted hinges, locks, automobile parts, motorcycle parts, gear box, lighting fixture parts, instrument enclosures, motor frames, foot pedals, and high precision machine parts etc.
Cast Metals:
1. Aluminium Die Casting: 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.
2. Zinc Die Casting: the easiest alloy to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life.
3. Magnesium Die Casting: the easiest alloy to machine; excellent strength-to-weight ratio; lightest alloy commonly die cast.
4. Copper Die Casting (Brass, Bronze): high hardness; high corrosion resistance; highest mechanical properties of alloys die cast; excellent wear resistance; excellent dimensional stability; strength approaching that of steel parts.
5. Lead and Tin Die Casting: high density; extremely close dimensional accuracy; used for special forms of corrosion resistance.

Aluminum Die Casting

Aluminum die casting provides casting parts with complex shape, thin walls and nice surface finish. This helps minimize follow-up machining and finishing operations. Typically a die casting mold is expensive, but the unit production cost is very economical.
Aluminum Die Castings Materials:
Frequently used materials:
A356, A360, A380, A390, A383, A413, AlSi10Mg, ADC-12, ADC-14, LM4, LM6, LM9
Standards:
ASTM B85 Die Castings

Zinc Die Casting

Zinc die casting uses hot chamber die casting, so it can be manufactured faster than aluminum die castings which uses cold chamber.
Zinc Die Castings Materials:
Zamak ZA3, ZA8, ZA12, ZA27, Zinc alloy 2, 3, 5, 7

Magnesium Die Casting

Magnesium is strong, rigid, fully recyclable, and is the ideal alloy for saving weight when you don’t want to sacrifice durability. It's 75% lighter than steel, 33% lighter than aluminum, offers component and feature integration and provides a high dimensional stability that improves fit and finish.
Magnesium Die Castings Materials:
AZ91D, AM60B, AM60, AM50

Brass Die Casting (Bronze Die Casting)

We provide high quality, high performance and low cost brass die casting (bronze die casting) when your casting parts require high strength, corrosion resistance, heat resistance, conductivity and attractive appearance.
