A very important issue is that there is no unified rule for setting of shrinkage rate of two-color mold, and key issue is whether to set shrinkage rate for material for second injection. Materials and glue levels depend on structure of the entire product. If material for second injection is soft rubber, and plastic part itself is very small, soft rubber can usually have same shrinkage rate as hard rubber. Shrinkage rate of soft rubber of two-color mold needs to be determined according to specific structure of plastic part, and it is usually necessary to accumulate experience in practice.
