Applied Research on Contractive Rate Inspecting Testing Mould of Pressure Casting Alloy
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 alloy was bring forward through researching the contractive rate of alloy. Using the method a inspecting testing mould of alloy was designed , and the real contractive rate was mastered 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.
