PARA Gating System and Floating Fiber
ظاهرة المشكلة
Improper PARA gating system design causes floating fiber; flow distance too long, glass fiber and resin separate.
تحليل الأسباب
Glass fiber reinforced plastic has poor flowability and the flowability of glass fiber and resin components is inconsistent; flow distance cannot be too long; the melt must fill the cavity quickly to ensure uniform glass fiber dispersion; stagnation and delamination form floating fiber.
الحل
①Design the gating system for short flow; ②Melt fills the cavity quickly; ③Gate position optimizes the flow pattern; ④Runner size sufficient.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
The short-flow fast-filling principle of the PARA gating system prevents floating fiber; the flowability difference of the two components is the design starting point; uniform dispersion depends on flow management.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
