Dongguan Hengrong Machinery Co., Ltd. is a professional manufacturer specializing in peripheral equipment for plastic machinery. With years of experience and in-depth technical knowledge, the company's engineers have developed practical solutions to common issues faced in plastic processing. Below are some key factors that may lead to material shortages during the molding process, along with recommended adjustments:
**Underlined: "Lack of Material"**
1. **Melt temperature is too low**: Increasing the temperature of the barrel and nozzle can help improve melt flow and ensure sufficient material is available during injection.
2. **Short molding cycle**: Extending the overall cycle time allows more material to be fed into the mold, reducing the risk of underfilling.
3. **Slow injection speed**: Adjusting the injection speed to an appropriate level can enhance material flow and reduce the chance of incomplete filling.
4. **Short holding time**: Increasing the holding time ensures that the mold remains properly filled until the material solidifies.
5. **Insufficient material supply**: Increasing the amount of material being fed into the system can help avoid shortages during the molding process.
6. **Low screw back pressure**: Properly increasing the back pressure helps improve the mixing and compaction of the material, ensuring better consistency.
7. **Small gate or runner size**: Enlarging the gate and runner sections can improve material flow and reduce resistance during injection.
8. **Poor mold venting**: Enhancing the mold’s ventilation by adding more vent holes can prevent air entrapment and improve the quality of the final product.
9. **Inadequate mold strength**: Ensuring the mold has sufficient rigidity prevents deformation during high-pressure injection, maintaining consistent part quality.
By addressing these factors, manufacturers can significantly reduce the occurrence of material shortages and improve overall production efficiency. Dongguan Hengrong Machinery Co., Ltd. continues to support its clients with innovative solutions and expert advice to optimize their plastic manufacturing processes.
