Qingdao Beihai Hardware Co.,Ltd is one the leading China the machine accessories manufacturers and suppliers with products processing, welcome to import OEM the machine accessories from our factory.Die casting is a metal casting process, its characteristic is to use the mold cavity of melting metal under pressure. Moulds are usually with higher strength alloy processing, this some similar molding process. Most die castings are not iron, such as zinc, copper, aluminum, magnesium, lead, tin and lead tin alloy and their alloys. According to different types of die casting, need to use the cold chamber die casting machine and hot chamber die casting machine.Casting equipment and die of expensive, so the die casting technology in general will only be used for batch manufacturing of products. Make the parts of the die casting is relatively easy, this generally need only four main steps, single cost increment is very low. Die casting is especially suitable for manufacturing a large number of small and medium sized castings, so die casting is the most widely used in all kinds of casting process. Compared with other casting technology, the surface of the die casting is more smooth, consistent with a higher size.On the basis of the traditional die casting technology was born several kinds of advanced technology, including reducing the casting defect elimination pores without hole die casting technology. Mainly used for processing zinc, can reduce waste to increase yield of direct injection technology. General dynamics and invented by semi-solid die casting die casting technology and fine speed and so on the new die casting technology.
