CASE STUDY

INSERT MOLDING OF DOUBLE COLOR BASIN

CHALLENGES

The double color basin produced by inserting plastic decoration component into the basin mould and through insert molding process, the product will have appearance in double colors. The plastic insert has more uncertainty of shrinkage than metal insert. 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.
