Shenzhen top mold factory: injection mold production and processing manufacturing process, the color dark and poor gloss how to solve？
1. Poor finish of the injection mold, rust on the surface of the cavity, etc., poor mold exhaust;
2. Using too much recycled material, poor quality of plastic or colorant, mixed with water vapor or other impurities, using poor quality lubricants;
3. injection mold casting system is defective, should increase the cold material well, increase the runner, polishing the main flow channel, manifold and gate;
4. The material temperature and mold temperature is low, if necessary, the gate can be used to local heating methods;
5. Plastic should be fully plasticized, but to prevent material degradation, heat should be stable, cooling should be sufficient, especially thick-walled;
6. injection mold manufacturing process clamping force should be sufficient;
7. injection mold processing pressure is too low, too slow, insufficient injection time, insufficient back pressure, resulting in poor compactness and make the surface dark;
8. Prevent cold material into the parts, if necessary, change to self-locking spring or reduce the nozzle temperature;
Do the above 8 points can be very good to avoid the injection molds appear amount of fish dark and poor luster phenomenon, even in the production process of such phenomena can also be very good to do a good job of remedial measures to minimize the impact on the production schedule of enterprises, improve the production efficiency of enterprises.
