Flash at the Parting Line of PBT
문제 현상
Flash and burrs appear at the parting line of PBT products.
원인 분석
The melt viscosity of PBT is relatively low and the fluidity is good, so it easily overflows from the parting line; the clamping force is insufficient; the injection pressure is too high.
해결 방법
Increase the clamping force; repair the flatness of the parting line; appropriately reduce the injection pressure; use a precision parting line design.
핵심 요약
PBT has good fluidity and is prone to flash, which needs attention.
