PC Product Abnormal Dimensional Shrinkage After Demolding

For PC dimensional deviation, 'first unify the measurement benchmark': non-unified measurement conditions are the illusion of many 'drifts'; PC's low shrinkage does not mean you can do whatever you want, the benchmark must come first.

GF-PC Surface Floating Fiber

GF-PC floating fiber = 'insufficient encapsulation': raise temperature and slow down to let the resin wrap the fibers; the appearance surface needs process + texture + grade cooperation, and machine adjustment alone is hard to eradicate it.

GF-PC Warpage (Fiber Orientation)

For GF-PC warpage, 'first look at the fiber orientation map': gate design is the breakthrough point; orientation-type warpage has a fixed direction, pressing it hard with cooling is ineffective, it must be adjusted from the orientation source.
