What is shrink and shrinkage, what is 2plate and 3plate mold

Question

Accepted Answer

Shrink is the reduction in size of a plastic part during cooling, while shrinkage refers to the percentage of size reduction. 2plate and 3plate molds are types of injection molds used in plastic part manufacturing.

Shrink is caused by the cooling and solidification of the plastic material.
Shrinkage is expressed as a percentage and is calculated by comparing the dimensions of the molded part to the dimensions of the mold.
2plate molds consist of two plates that separate to eject the molded part, while 3plate molds have an additional plate that allows for the creation of undercuts or complex part geometries.
2plate molds are simpler and less expensive, but may require additional post-processing steps to remove undercuts.
3plate molds offer more design flexibility but are more complex and costly to manufacture.
