Source Control of PU Foam Scrap and Defects in Taizhou Production
Reduce Finishing through Better Design
Parting, overflow channels and insert structure influence trimming and secondary work. Repeated cutting or grinding should trigger a product and tooling review.
Stable Parameters Beat End-of-Line Sorting
Variation in shot weight, mold temperature and curing causes short fill, bubbles, shrinkage and distortion. First-piece approval and process records control defects at the source.
Convert Trial Findings into Standards
Mold-trial findings should become tool changes, operating requirements or inspection items so they do not recur across shifts and batches.
Application Perspective from Taizhou and Zhejiang
The Taizhou facility works with Huangyan tooling and the regional EV supply chain. Parameters in this article should be confirmed against the actual component and operating environment.
