As one of the CNC machining manufacturing companies in china, ETCN CNC china machining and manufacturing covering different fields in china CNC machining and manufacturing services like iron metal casting services, CNC machining (including plastic) services, CNC milling services, CNC punching services and CNC turning services china. ETCN struggles with what to call ourselves since we are not a traditional machine shop, seller, or a metal parts supplier. ETCN also provides medical devices of CNC machining in medical industry. Once you work with ECN, you will believe us as the trusted and professional partner.
Die Casting
As a professional aluminum die casting co inc 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, hot chamber pressure die casting, aluminum pressure die casting, cast iron die casting, brass die casting, copper die casting, injection die casting, mould die casting and etc.
Advantage of Die Casting
High Material Utilization Rate
Due to the high precision of casting process, die casting and sand casting parts 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%.
Good Product Quality
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 be used in 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.
High Production Efficiency
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 and cold 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.
Excellent Economic Effect
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. Our mental casting services like iron casting services save not only assembly man-hours but also metal.
Easy To Use Inserts
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.
