Dimensional Shrinkage of PC Products
Problem Phenomenon
The PC '2079851475616104452 shrinkage is 0.5-0.7%, and its fluctuation affects dimensional accuracy.
Cause Analysis
PC is an amorphous material; its shrinkage is related to holding pressure, mold temperature, and cooling; process fluctuations cause shrinkage changes.
Solution
Stabilize the holding pressure and extend the shrinkage compensation; keep the mold temperature consistent; keep the parameters of each shot consistent.
Key Takeaway
PC shrinkage control is the basis of precision parts.
