Therefore, controlling the shrinkage allowance between plastic insert mould and principal mould is a key element in the insert molding process.


ENGINEERING & TECHNOLOGY

Having rich experience, Jeward design team could calculate accurately the shrinkage allowance of mould according to the target materiel. We do repeated test in mould testing period and record the best parameters. So that customers could set up the their injection machine quickly after receiving our mould.
