Large negative pressure suction machine is molding process steps

Large vacuum forming process has three main points, namely large negative pressure suction machine is 1 2 3 set conditions forming equipment and raw materials forming mold. Large blister is forming negative pressure suction machine materials into finished products, the first topic is large blister material formability, is the ease of forming. This alone and their physical, chemical, and mechanical temper, plasticizing, material and process flow, process conditions of progressive die. Solve the subject bag ever important to rely on the people operating experience, but have operating experience is limited, can't solve such questions. Special is very many scholars conducted a lot of theoretical and experimental research on baidu ranked, with computer imitation of forming process has entered the stage of practical application. As large blister varieties growing, finished product persist to expand, also persist the forming process of innovation. With injection molding and extrusion molding innovation most, plate hot forming technology and agile development. Devices will become more and more have a high level of initiative and computer all active control, have been implemented in extrusion, injection, hot forming. But mould design and manufacturing is still lagged behind the development of equipment and process methods, important embodiment in the low level of mold design and manufacturing, production cycle is long, short service life.
