What are the common problems and solutions of Small Plastic Fitting Injection Molding Mould Machine?
● During the processing of Small Plastic Fitting Injection Molding Mould Machine, the mold can not be filled. At the beginning of the operation of the injection molding machine, due to the low mold temperature, the heat loss of PVC molten material is large, which is easy to solidify, the resistance of the mold cavity is large, and the material can not fill the mold cavity. This phenomenon is normal, but it will disappear automatically after continuous injection.
● The ZOWEITE® Small Plastic Fitting Injection Molding Mould Machine causes of shrinkage mark have something in common with the causes of insufficient injection, specifically:
1. The set injection pressure is low, so the injection pressure can be increased appropriately.
2. If the set pressure holding time is not enough, the pressure holding time can be increased appropriately.
3. If the set cooling time is not enough, the cooling time can be appropriately increased.
4. If the amount of sol is insufficient, increase the amount of sol appropriately.
5. If the water transportation of the die is uneven, the cooling circuit can be adjusted to make the cooling of all parts of the die uniform.
6. The structural size of the mold gating system is too small. You can increase the gate or the section size of the main, sub and runner.
● When white pipe fittings are processed by Small Plastic Fitting Injection Molding Mould Machine, red or blue stripes are easy to appear. This phenomenon is also related to the gating system in the mold. The gate is a very important part of the mold. Because the gate is the gateway for the melt to enter the mold, the material flow resistance is the largest and the temperature is the highest. It is easy to cause discoloration on the surface of the product. Therefore, the resistance and temperature change that can reduce the material flow must be considered in the gate design. This is why we should follow the principles of large gate size rather than small, short gate channel rather than long, thick rather than thin in pouring design. Also, the design of die cold charging well is very important. In addition, excessive melt temperature, too fast injection speed and poor mold exhaust will also produce product surface discoloration, which can be solved by adjusting process temperature and parameters.
● The surface gloss difference of PVC Small Plastic Fitting Injection Molding Mould Machine molded products is largely related to the fluidity of PVC materials. Therefore, improving the fluidity of materials is an important measure to improve the quality of products. Specifically:
1. Due to the low temperature of the molten material, the fluidity of the material is poor. The heating temperature of the material can be appropriately increased, especially at the nozzle.
2. If the formula is unreasonable, so that the plasticization of materials cannot be in place or there are too many fillers, the formula shall be adjusted, the plasticization quality and fluidity of materials shall be improved through the reasonable cooperation of processing additives, and the dosage of fillers shall be controlled.
3. ZOWEITE® Small Plastic Fitting Injection Molding Mould Machine Insufficient mold cooling to improve mold cooling effect.
4. If the gate size is too small or the channel section is too small and the resistance is too large, the channel section can be appropriately increased, the gate can be increased and the resistance can be reduced.
5. If the content of water or other volatiles in the raw materials is too high, the raw materials can be fully dried, or the water or volatiles can be removed by making materials.
6. If the exhaust is poor, an exhaust slot can be added or the gate position can be changed.
