Die Casting Process

Die casting is the manufacturing process of choice when producing high volumes of relatively complex metal parts and is widely used due to its versatility, reliability, and accuracy. Die casting eliminates all or most secondary operations needed to make a metal part; however, post-machining is common to meet tighter critical-to-function tolerances. Die casting parts can also be post-processed in any finish their respective CNC machined counterparts can.

Die casting can produce highly complex, tight-tolerance parts in a repeatable manner at very high production volumes. Modern die casting methods such as squeeze casting and semi-solid metal casting produce high-quality parts for nearly every industry. Die casting companies will often specialize in casting aluminum or zinc, with aluminum making up roughly 80% of die cast parts.

Our project managers and experts personally review and manually quote each die casting project to ensure we meet your unique needs while providing a fast and easy manufacturing experience.

What we can offers for you?

Aluminum Die Casting

Aluminum alloys are the most widely used for die cast parts. Aluminum die casting suppliers benefit from the total recyclability of the material and its ease of use. Due to the comparatively higher melting point, aluminum die casting may require a cold chamber casting process. Engineers use cast aluminum parts primarily for their great strength to weight ratios, dimensional stability, and diverse finishing options. Some of the other common characteristics of cast aluminum alloys are:

Withstand high operating temperatures
Corrosion Resistance
Good stiffness
High thermal and electrical conductivity

Engineers and designers can choose from a wide range of alloys for their aluminum casting parts. Xometry offers the most popular aluminum die casting alloys, including:

A360.0
A380.0
A383.0 (ADC12)
A413.0

Zinc Die Casting

Zinc is the easiest to cast material among the die casting metals and is typically used in hot chamber processes. Molten zinc has exceptional casting fluidity and a lower melting point. Its strength and stiffness allow it to produce parts with thinner walls and highly detailed features and maintain tight tolerances. The low melting point of die casting zinc alloys means the die casted parts cool off and solidify more quickly, which results in the fastest production rates of the die casting materials. Zinc is an all-around well-performing material due to its balance of mechanical and physical characteristics, which include:

Impact strength
High hardness
Great stability
High-quality surface finish and easily plated
Low melting point

We offers the most popular types of Zamak and ZA die casting zinc alloys. More specifically, those alloys include:

Zamak 2 (ZA-2)
Zamak 3 (ZA-3)
