Die Casting Process and Its Advantages

Die casting process and its advantages
1. The product is of good quality
Castings have high dimensional accuracy, generally equivalent to grade 6~7, or even up to grade 4; good surface finish, generally equivalent to grade 5~8; high strength and hardness, and the strength is generally 25~30% higher than that of sand casting, but The elongation is reduced by about 70%; the dimension is stable and the interchangeability is good; it can die-cast thin-walled and complex castings. At present, the minimum wall thickness of zinc alloy die castings can reach 0.3mm; aluminum alloy castings can reach 0.5mm; the minimum casting hole diameter is 0.7mm, and the minimum pitch is 0.75mm.
2. High production efficiency of precision die casting
The machine has high productivity, the horizontal cold air die-casting machine can die-cast 600-700 times in an average of eight hours, and the small hot-chamber die-casting machine can die-cast 3000-7000 times per eight hours on average; The lifespan can reach hundreds of thousands or even millions; it is easy to realize mechanization and automation.
3. The economic effect of precision die casting is excellent
Due to the precise size of the die-casting parts, the surface is smooth and clean. Generally, it is not used directly without mechanical processing, or the processing volume is very small, so it not only improves the metal utilization rate, but also reduces a large number of processing equipment and man-hours; the price of castings is easy; combined die-casting can be used with other metal or non-metallic materials. , which saves both assembly man-hours and metal.
