Insufficient toughness of PCTG short-cycle parts
문제 현상
Impact strength of thin-wall rapid molding parts does not meet standards.
원인 분석
Fast cooling freezes molecular chain orientation, insufficient toughness, unreleased internal stress.
해결 방법
Extend cooling time or increase mold temperature; annealing treatment; use toughened grades.
핵심 요약
PCTG thin-wall toughness is greatly affected by cooling.
