Precision Die Casts  Manufacturers, Traders, Suppliers

Zinc Alloy Castings are precision-engineered components produced through the die-casting process, using high-quality zinc alloys for superior strength, durability, and dimensional accuracy. Zinc alloy castings offer excellent corrosion resistance, high hardness, and a smooth surface finish, making them ideal for complex shapes and intricate designs. Widely used in automotive, electronics, telecommunications, hardware, and consumer products industries, these castings are cost-effective for high-volume production while ensuring consistent quality and performance.

1.Temperature control
Pouring temperature:
Silicon aluminum alloy (such as ADC12): simple structural components at 610-630 ° C, complex components at 644-680 ° C 12.
Alloys with poor fluidity require an increase in temperature (e.g. A380 alloy can reach 720 ° C).
Mold temperature:
Aluminum alloy molds are recommended to be heated between 200-280 ° C, with higher temperatures required for thin-walled/complex parts.
2.Injection parameters
Injection speed:
Slow stage 0.1-0.5m/s (exhaust), fast stage 2-6m/s (filling) 45.
Thin walled components require a speed of ≥ 4m/s, while thick walled components can reduce the speed by 5.
Pressure ratio:
Thin walled components have a pressure range of 80-120MPa, while thick walled components can reduce pressure but require an increase of 5% in boost pressure.
3.Time parameter
Filling time: 0.01-0.1 seconds, extended by 3 seconds when the alloy temperature is high or the mold heat dissipation is fast.
Pressure holding time: ≥ 2 seconds, with an extension of 0.5 seconds for every 1mm increase in thick walled components.
4.Material and Composition Standards
ADC12 (Japanese standard, silicon content 10.5-12%), A380 (American standard, good fluidity) 7.
Domestic Y102/Y112 are suitable for different strength requirements.
Composition requirements:
Aluminum content ≥ 90%, silicon 7-12%, copper/magnesium adjusted by grade 8.
