Compression mould usually use hydraulic press machine and the cavity and core is fixed to top and bottom platens of machine. Once the material is placed into the open mould, the machine closes, mould get heated, then the press pressure force material to flow all over the mould.
SMC mould design follows similar rules as for any other production process with the plastic industry. But before you build a SMC mould, there are certain things need to be considered.The first and most important is shear edge.
Mould shrinkage
There are two shrinkage for SMC mould. Low profile class A part have a shrinkage of -0.05% to 0%.
