PETG and elastomer overmolding poor bonding
문제 현상
When overmolding TPE/TPU elastomer onto a rigid substrate, the bonding force is insufficient.
원인 분석
The substrate surface cools quickly and wets poorly, the materials are incompatible, and the substrate surface is untreated.
해결 방법
Plasma or primer pretreatment of the substrate surface; increase the overmolding material temperature; select a compatible elastomer.
핵심 요약
PETG overmolding requires substrate pretreatment and material selection.
