How to deal with the overflow of precision insert injection molding

Precision insert injection molding is widely used in various fields such as automobiles, electronics, and household appliances. Precision is a manufacturer that produces precision insert injection molding and precision metal stamping. In our actual production process, we will find various defects that may occur in injection molding, such as bubbles, warpage, deformation, edge overflow, and residual stress. Cracks, shrinkage pits, insufficient filling, etc. This article will tell you how to deal with overflow. The treatment point for the overflow should be mainly placed on the improvement of the mold. In terms of molding conditions, you can start to reduce fluidity. Specifically, the following methods can be used: 1. Reduce the injection pressure. 2. Lower the resin temperature. 3. Choose high-viscosity grade materials. 4. Lower the mold temperature. 5. Grind the mold surface where flashover occurs. 6. Use harder mold steel. 7. Improve the clamping force. 8. Adjust the bonding surface and other parts of the accurate mold. 9. Increase mold support column to increase rigidity. 10. Determine the size of different exhaust grooves according to different materials.
