Aluminum Alloy Die Caasting Fabrication Services

The essence of die casting is the method of filling the die casting mold cavity with liquid or semi liquid metal at a high speed under high pressure, and forming and solidifying under pressure to obtain castings.

Advantages of Die Casting:

1. Good product quality

The dimensional accuracy of castings is high, generally equivalent to levels 6-7, and even up to level 4; Good surface smoothness, generally equivalent to grades 5-8; The strength and hardness are relatively high, and the strength is generally increased by 25-30% compared to sand casting, but the elongation is reduced by about 70%; Stable size and good interchangeability; Can die cast thin-walled and complex castings. For example, the current zinc alloy die-casting parts can have a small wall thickness of up to 0.3mm; Aluminum alloy castings can reach 0.5mm; The small casting aperture is 0.7mm; The small pitch is 0.75mm.

2. High production efficiency

The machine has high productivity, for example, the domestically produced J-III3 horizontal cold air die casting machine can die cast 600-700 times on average in eight hours, and the small hot chamber die casting machine can die cast 3000-7000 times on average every eight hours; Die casting molds have a long lifespan, with a pair of die casting molds and die cast bell alloys having a lifespan of several hundred thousand times, or even millions of times; Easy to achieve mechanization and automation.

3. Excellent economic results

Due to the advantages of precise size and smooth surface of die-casting parts. Generally, it is used directly without mechanical processing, or the processing volume is very small, which not only improves the metal utilization rate but also reduces a large number of processing equipment and working hours; The cost of castings is easy; Combination die casting can be used with other metal or non-metallic materials. It saves both assembly time and metal.
