Brittle edges and crumb shedding of PP products

PP brittle edges = check both 'stress + degradation': first reduce stress (fillets, holding pressure), then control degradation (temperature, regrind), and finally manage trimming tools well; edge problems are often a barometer of the stress state of the whole part.

PP Part Stress Whitening

Stress whitening is a clear signal of PP 'local yielding'; the control approach is to disperse concentrated forces (starting from ejection, assembly, and structure), not to cover it up; it is a free 'stress indicator'—use it well to locate structural weak points.
