the shrinkage of plastic parts, due to the nature of plastic ( to expand when hot and to shrink when cold), the dimension of plastic parts after molding and cooling is smaller than that of the cavity.

almost all mold engineers and molding engineers may understand this issue
I think we can discuss this issue here, and hope more molding engineers and mould designers come here
For injection molding, shrinkage is inevitable
yes! but it is not easy to control
but shrinkage is not easy to control
Different batches of the same material, the shrinkage rate is likely to be different
shrinkage is an uncertainty, I mean it is difficult to accurately control
yes! shrinkage is very important
This is inevitable,so correct shrinkage is very important
nylon is a sample,As a molding material, it’s working dimension is very difficult to control
