Annealing Deformation of PBT Products
문제 현상
PBT products deform during annealing treatment, and the dimensions change after annealing.
원인 분석
The annealing temperature is too high, approaching the softening point of PBT; there is no support or improper support during annealing; the release of internal stress of the product is accompanied by deformation.
해결 방법
Control the annealing temperature at 120-130°C; use fixtures to support and maintain the shape; raise and lower the temperature slowly.
핵심 요약
PBT annealing deformation requires suitable tooling and heating rate.
