Improper injection speed adjustment producing surface defects
문제 현상
Excessive injection speed produces jetting and elastic turbulence, and too low speed causes underfilling
원인 분석
PEI melt is relatively sensitive to shear rate; unreasonable injection speed curves cause flow instability
해결 방법
Use a multi-stage injection speed control curve (slow→fast→slow); optimize the speed segmentation settings according to product geometry; combine mold flow analysis to guide speed curve design
핵심 요약
Precise injection speed control is the key to obtaining high-quality PEI products
