The mechanical system of injection machine design
Abstract：Injection molding machine and injection molding machine and injection machine, many factories called PI JI, injection molding products is called PI JIAN. It is the thermoplastic or thermosetting material using plastic molding mold made into various shapes of plastic products mainly molding equipment. Injection molding machine according to the injection device and clamping device arrangement, can be pided into vertical, horizontal and vertical lie compound.Injection molding machine is one of the largest processing machinery, plastic processing industry in the usage not only have a large number of products available injection molding machine production directly, but also of note, blowing process of key equipment. China has become the world's largest country in machines in PCS/sets of production, the reason: to promote the development of China's injection molding machine equipment manufacturing is a joint venture with international famous enterprises and technological cooperation; Second, Chinese enterprises gradually adapted to the mechanical parts adopt international purchase way, mastered the as purchase channels. At the same time, the production of the injection molding machine of our country present a strong regional features, Ningbo in Zhejiang province and Guangdong Dongguan and other places, has become China's important production base of injection molding machine and the world.
