Types of Pressure Die Casting
Pressure die casting is a quick and one of the most cost-effective manufacturing methods to produce dimensional accurate metal parts. Basically, types of pressure die casting process is made by injecting molten metal into a reusable steel molds（also called dies or tools)under high pressure.
Advantages of Pressure Die Casting
Cost SavingCost Saving
Lowest cost-per-piece for large production volume (10,000+ pieces)

DurabilityDurability
High Pressure Die Casting process produces highly durable parts well-suited for both functional prototypes and end-use production.
Great Thin Wall Capability Great Thin Wall Capability
Die Casting allows for thinner walls.
Smooth SurfaceSmooth Surface
The high pressure casting process provides smoother finishes than all other forms of casting.
Pressure Die Casting Process
There are following steps after we receive the order from you:
Review drawing and assess any potential manufacturability issues and defects in DFM analysis stage.
Verify the tool material.
Use our full in-house machine shop to fabricate the mold tool.
Apply lubricant to ease the removal of the cast part and maintain the mold temperature.
Perform in process control during the casting process to ensure quality.
Offer a broad range of finishing services to make you parts flawless.
Inspect finished parts to exceed your expectations.
Pressure Die Casting Tolerance
The tolerances standard we are using is from NADCA, which is showing in below table (linear dimensions). For other tolerances please refer to NADCA. However, if you need a tighter tolerance, then a tighter tolerances standard can be achieved once we have confirmed your pressure die casting design.
Pressure Die Casting Materials
Magnesium alloy (Liquid Temperature: 630℃~650℃ for hot chamber die-casting machine, 650℃~680℃for cold chamber die-casting machine)
Magnesium is excellent with it’s extraordinary strength-to-weight ratios and outstanding mechanical performance.
The commonly-used magnesium alloy material is AZ91D.
Magnesium alloy (Liquid Temperature: 630℃~650℃ for hot chamber die-casting machine, 650℃~680℃for cold chamber die-casting machine)
Mold Tools
High pressure die casting mold tool material is only referred to cavity/ inside of tooling, normally the mold base or other components are 45# or a cheaper material.
Normally we will use H13 as the cavity material. If the parts require large quantity in the future, we can consider to use imported material, such as 8408, 8407 from Sweden, but they are much more expensive.
Mold Tools
We specialize in superior aluminum, magnesium and zinc alloy die casting. When finding out what material you are going to use for the project, you need take many factors into consideration, including cost, weight, performance, cast ability, weather condition and application environment.
Die Casting Parts
Aluminum Alloy (Liquid Temperature: 650 +/- 20 ℃)
Aluminum is known for its great temperature resistance and extremely lightweight. Besides, it is the most suitable choice for the exterior parts because it can be highly polished.
Common high pressure die casting aluminum alloys are ADC12, A380, and A413.
ADC12: (Japanese designation) the most common aluminum alloy, which is used a lot for parts with no special requirements.
A380: (American designation) the most common aluminum alloy used in the USA.
A413: better but more expensive.
Aluminum Alloy (Liquid Temperature: 650 +/- 20 ℃)
Zinc Alloy (Liquid Temperature: 420~450℃)
Zinc is ideal for applications that require high strength and strong corrosion resistance. Zinc alloys are an great choice for plating. It is also highly desirable for die casting parts because it is the cheapest one.
Zamak and Mazak are the same meaning as Zinc alloy. The common material is Zinc 3# and Zinc 5#.
