The elements of vacuum forming process

Large vacuum molding process has three elements: the large vacuum forming equipment and raw materials, forming set conditions and forming mould. Vacuum forming large vacuum forming materials forming into products, the first question is a large vacuum forming material formability, namely the ease of forming. This is not only related to physical, chemical and mechanical properties of itself, and plasticizing, material and process flow, process conditions of progressive die. To solve this problem in the past relied on people's experience, but experience is limited, can not successfully solve the problem. Many scholars have conducted a lot of theoretical and experimental research, using computer to simulate the forming process has entered the stage of practical application. With the increasing of large varieties of vacuum forming, expanding products, forming process and continuous innovation. With injection molding and extrusion molding innovation most, plate hot forming technology is also developing rapidly. Devices will become more and more high degree of automation, the computer full automatic control, has been implemented in extrusion, injection, hot forming. But mould design and manufacturing is still lagged behind the development of equipment and process methods, main performance in the low level of mold design and manufacturing, production cycle is long, short service life.
