Introduction of Die Casting
2016-11-01
Die casting is a metal casting process, which is characterized by the use of mold cavity to melt the metal to exert high pressure. Molds are usually made of alloys of higher strength, and this process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys, and alloys thereof. According to the different types of die-casting, the need to use cold chamber die casting machine or hot chamber die-casting machine.
 
Casting equipment and molds are expensive, so the die-casting process is generally only used to batch manufacture a large number of products. It is relatively easy to manufacture die-cast parts, which typically require only four major steps, with a small incremental cost per item. Die casting is particularly suitable for the manufacture of a large number of small and medium sized castings, casting is therefore a variety of casting the most widely used one. Compared with other casting technology, die-casting surface is more flat, with a higher dimensional consistency.
 
On the basis of the traditional die-casting process, several improved processes were introduced, including the non-porous die-casting process to reduce the casting defects and remove the pores. Mainly used for processing zinc, can reduce the waste to increase the yield of direct injection process. As well as by the General Dynamics invented the rapid precision die-casting technology and semi-solid die-casting process, and so on a new type of die-casting process.
