Factors that affect the size of plastic parts:
A. Forming the parts themselves
B. Wear in the course of use
C. The fluctuation of shrinkage
Specific size calculation:
<1> Radial size calculation
A. Cavity L cavity:
B. Core L-core =
C. Center cavity:
Among them: ① parts of the size of the form must be converted into the form of the map
③ The above calculation is based on the average shrinkage calculation formula feed
④ for the accuracy requirements of more than 6 products, mold size calculation results need to retain two decimal places, 6 precision below, only one can be retained.
