Study on Contractive Rate Inspecting Testing Mould of Thermoplastic

Abstract:

As we know , the materials will swell and contract when it is heated or cooled . A kind of method for mastery the real contractive rate of thermoplastic was bring forward through researching the contractive rate of thermoplastic . Using the method a inspecting testing mould of thermoplastic was designed , and the real contractive rate was masteried by the mould . And this provides the reliable contract date for the design of mould cavity dimension , and reduces the work of mould repair , and also save a lot of money and labor.
