As a professional aluminum die casting manufacturer, ETCN provides our clients qualified die casting service. The product uses a die-casting process to complete the blank, CNC machining and polishing treatment, suitable for auto parts. In addition, die-casting service includes different types of materials such as zinc pressure die casting, aluminum pressure die casting, brass die casting, copper die casting and etc.
Due to the high precision of die-casting parts, it can be assembled and used only after a small amount of mechanical processing, and some die-casting parts can be directly assembled and used. The material utilization rate is about 60%-80%, and the blank utilization rate reaches 90%.
The dimensional accuracy of die casting engineering is high, generally equivalent to 6~7, or even up to 4; the surface finish is good, generally equivalent to 5~8; the strength and hardness are higher, and the strength is generally 25~30% higher than sand casting, but it is extended The rate is reduced by about 70%; the size is stable, and the interchangeability is good; it can die-cast thin-walled complex castings. For example, the current minimum wall thickness of zinc alloy die castings can reach 0.3 mm; aluminum alloy castings can reach 0.5 mm; the minimum casting aperture is 0.7 mm, and the minimum pitch is 0.75 mm.
Machine productivity is high. For example, the domestic JⅢ3 horizontal cold-air die casting machine can die-cast 600-700 times in eight hours on average, and the small hot-chamber die-casting machine can die-cast 3,000-7000 times in eight hours on average. The die-casting mold has a long life and one pair of die-casting molds. The die-cast clock alloy has a life span of hundreds of thousands or even millions of times; it is easy to realize mechanization and automation.
Due to the precise size of the die-casting, the surface is smooth and clean. Generally, it is not used for mechanical processing but directly used, or the processing volume is small, so it not only improves the utilization rate of metal but also reduces a large number of processing equipment and man-hours; and reduces die casting cost; combination die-casting can be used with other metal or non-metal materials. It saves not only assembly man-hours but also metal.
It is easy to set a positioning mechanism on the die-casting mold to facilitate insert casting of inserts and meet the local special performance requirements of die-casting parts.
