- Category: Case Studies, Design Tips, Industry News, White Papers
The basic reason for surface sag: from the perspective of plastics, when the plastic cools and shrink, insufficient filling will lead to product surface sag or internal cavity. The causes and solutions of defects are different depending on the location of sag. When the sag occurs at the final cooling position of the thick-walled product,

COMMON PROBLEMS IN INJECTION MOLDING INSUFFICIENT FILLING
- December 11, 2019
- Posted by: Molding
- Category: Case Studies, Industry News, White Papers
The main reasons for insufficient filling are as follows: 1) insufficient resin capacity. 2) insufficient pressure in the cavity. 3) resin fluidity is insufficient. 4) poor exhaust effect. As an improvement measure, we can start from the following aspects: 1) lengthen the injection time to prevent the resin countercurrent before the gate solidification due to
