How to make plastic shrink?
The factors affecting the shrinkage of plastics include: plastic varieties, molding conditions, mold structure and so on. The shrinkage rates of different polymers are different. Secondly, the shrinkage of plastic is closely related to the shape of plastic parts, the complexity of internal structure, and whether there are inserts or not.
The shrinkage of plastic is the percentage of the size of the plastic parts at the molding temperature and the size of the mold after being removed from the mold and cooled to room temperature. It reflects the extent to which plastic parts are removed from the mold and cooled to a reduced size.
A reduction in the temperature of the plastic will shrink the plastic.Plastic is expansion and contraction, and the greater the general shrinkage, the more easily deformed plastic. Different plastics, shrinkage is not the same.
