Zinc Die Casting
Zinc die casting is the ideal metal for die casting. Its characteristics of easy flow and low-temperature melt enable casting complex shapes easily, make very thin walls that are strong nonetheless, and keep using one set of tools practically forever.
At Pintejin Foundry, we can produce zinc die castings to meet the exact geometric specifications and details of your project. Our on-site infrastructure enables our team able to deliver small one-off orders, demanding ongoing production schedules and everything in between. As a leading zinc die casting company, we can produce parts and components to your exact specifications with heat treatments.

Features Of Zinc Die Castings
During the production of zinc alloy die casting, a different shape is required, from the simplest to the most complex designs are suitable. Casting is more appropriate than other processes. For the production of zinc width measurement part mixes, this technology has created die castings with smooth surfaces as well as good dimensional accuracy and identification. In the production process of zinc alloy die casting, the die casting process of zinc alloy die casting has special characteristics and advantages.
- The specific gravity is large, the weight is more textured, and it is stronger than plastic injection molding.
- Good casting performance, it can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
- Surface treatment is available: electroplating, spraying, painting.
- It does not absorb iron during melting and die-casting, does not corrode the molding, and does not stick to the mold.
- It has good mechanical properties and wear resistance at room temperature.
- Low melting point, melting at 385℃, easier to form than aluminum alloy die casting
- Zinc alloy has a strong three-dimensional effect, and the surface will have graininess or wrinkles after die casting, which needs to be polished. Polishing does not completely change the physical form.
- Zinc alloy handicrafts and embossed patterns are vivid and widely used, but they require a high level of craftsmanship, and there will be a small number of indentations or burrs on the surface.
What Is Zinc Die Casting?
Zinc alloy is an alloy composed of other elements based on zinc. The alloying elements that are often added are aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, easy recycling and remelting of residual waste, but low creep strength, prone to natural aging and dimensional changes. Prepared by melting, die casting or pressure processing.
Zinc alloys can be divided into cast zinc alloys and deformed zinc alloys according to the manufacturing process. Cast zinc alloy has good fluidity and corrosion resistance, and is suitable for zinc die casting instruments, automobile parts casings, etc.
The Alloy Type Of Die Casting Zinc
Zinc alloys can be divided into cast zinc alloys and deformed zinc alloys according to the manufacturing process. The output of cast alloys is much greater than that of wrought alloys.
Cast zinc alloys are divided into pressure cast zinc alloys (solidified under the action of external pressure) and gravity cast zinc alloys (solidified only under the action of gravity) according to different casting methods.
Die Casting Zinc Alloy: Since the application of this alloy in the automobile industry in 1940, the production has increased sharply, and about 25% of the total consumption of zinc is used to produce this alloy. Advanced and applicable technologies are constantly being adopted and developing rapidly. The most commonly used alloy system is Zn-Al-Cu-Mg system. Certain impurities significantly affect the properties of die-cast zinc alloys. Therefore, the content of iron, lead, cadmium, tin and other impurities is strictly limited, and the upper limits are 0.005%, 0.004%, 0.003%, and 0.02%, respectively. Therefore, high-purity zinc with a purity of more than 99.99% should be used as raw material for die-casting zinc alloy.
Gravity Cast Zinc Alloys: Can be cast in sand, plaster or hard molds. This zinc alloy not only has the characteristics of general die-casting zinc alloys, but also has high strength, good casting performance, cooling rate has no obvious effect on mechanical properties, remnants and scraps can be recycled, gate is simple, insensitive to overheating and remelting, shrinkage The rate is small, the pores are few, it can be electroplated, and it can be finished by conventional methods.
In addition to the traditional varieties, Zn-Cu-0.1Ti and Zn-22Al alloys appear in the wrought zinc alloys used in the wrought zinc alloy industry. After the former alloy is rolled, the grain boundary movement can be hindered due to the dispersed particles of TiZn15 intermetallic compounds arranged in a row along the rolling direction.
