You can check the melt temperature and melt flow. This will be in accordance with the supplier's instructions. Injection molding companies check the mold temperature and flow during the injection molding process. For unfilled resin, you can change the melt flow by 30%. For filled resin, you also change the melt flow by at least 40% or more.
1.8 Injecting too much melt
This is not a direct cause of flash. It is wrong to inject too much molten material to prevent shrinkage and this must be formed by increasing the injection time or holding time (see shrinkage).
1.9 Foreign matter on the mold surface
Foreign matter on the mold clamp surface will nepal number data inevitably cause burrs. To solve this problem, the surface of the clean mold should obviously be cleaned, and the clamp surface should be tightly adhered.
1.10 Caused by form deviation
If the originality of the mold is not enough, deviation will occur due to injection pressure. If there is a hole near the center, burrs will be formed around the hole. When the center gate is used to open the side gate, burrs can also be formed around the hole and the gate. The burrs caused by this reason are caused by poor mold making, so they are difficult to correct. Reinforced molds can reduce burrs.
Excessive residence time which creates degradation
