  • Design Fan Gate In Injection Mold

    What is fan gate? Fat gate, namely ,the shape of the gate looks like a fan.Fan gate is usually used on multi-cavity molds or two-plate molds. It is a common edge gate located located in the sidewalll of the part to prevent restriction of resin flow. Since the gate could distribute melt resin into the cavity more evenly, thus it is normally applicable to parts that require a high degree of flatness and absence of flow lines. It also minimizes the possibility of part warpage and helps to maintain dimensional stability.     From above pictures we could see that the fan gate has shortcomings as well. Since the gate is too wide and it may increase labor cost  to degate after molding. Besides the gate is long leaving visible trimming mark, it may affect cosmetic look as well. And there is high potentiality for air entrapment if not carefully…

  • How to Troubleshoot Flash Defect on Two Shot Injection Molding 

    What is flash in two shot injection molding? Description  2nd material penetrating between 1st material and its cavity. It is observed frequently where 1st material shrinkage is big and cooling time for 1  material is too long. It is mainly due to too fast shrinking of 1st material.   How to trouble shoot the flash? 1.Optimizing holding pressure & Cooling time to get min shrinking of 1st material till before 2nd shot molding. 2.Select less shrinkage rate material for 1st shot. 3.Changing design as preventive action. We’ve spent the past 15 years accumulating rich practical experience in solving the flash of two-shot injection molding. HS Mold has the design, engineering, and in-house tooling capabilities you need to streamline your project 2k injection molding project from conception to production.
