Extremely low strength at the weld line
문제 현상
The tensile strength at the weld line of PEEK products is only 30-40% of the base material
원인 분석
The temperature drops sharply at the melt convergence, causing insufficient molecular chain diffusion and entanglement; PEEK molecular chains are rigid, with diffusion rate far lower than flexible chains; the convergence surface cools quickly
해결 방법
Increase the mold temperature to above 200°C to extend the fusion window of the weld surface; optimize gate design to minimize the number of weld lines; use sequential valves to control the melt convergence timing
핵심 요약
PEEK weld lines are the main weak link in the product structure
