Injection Molding

Improper injection speed adjustment producing surface defects
Sorun Belirtisi
Excessive injection speed produces jetting and elastic turbulence, and too low speed causes underfilling
Neden Analizi
PEI melt is relatively sensitive to shear rate; unreasonable injection speed curves cause flow instability
Çözüm
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
Temel Çıkarım
Precise injection speed control is the key to obtaining high-quality PEI products
