Dongguan Hengrong Machinery Co., Ltd. is a professional manufacturer specializing in peripheral equipment for plastic machinery. With years of experience and deep technical knowledge, the engineering team has gained valuable insights into common issues faced in plastic molding processes. One of the most frequently encountered problems is "material shortage" during production. Below are some effective solutions to address this issue:
**Underlined: "Lack of Material"**
1. **Melt temperature is too low** – Increasing the temperature of the barrel and nozzle can help improve material flow and reduce the risk of underfilling.
2. **Short molding cycle** – Extending the cycle time allows more time for the material to fill the mold completely, ensuring better part quality.
3. **Injection speed is too slow** – Adjusting the injection speed to an appropriate level can enhance the filling process and prevent material shortages.
4. **Short holding time** – Increasing the holding time helps maintain pressure in the mold, which ensures proper packing of the material.
5. **Insufficient material supply** – Increasing the amount of raw material fed into the Machine can resolve the issue of insufficient supply.
6. **Low screw back pressure** – Raising the back pressure improves the mixing and compaction of the material, leading to better consistency and flow.
7. **Small gate or runner size** – Enlarging the gate and runner sections can improve material flow and reduce resistance during injection.
8. **Poor mold ventilation** – Adding more vent holes in the mold can help release trapped air, preventing voids and improving overall part quality.
9. **Inadequate mold strength** – Ensuring the mold has sufficient rigidity prevents deformation during high-pressure injection, maintaining consistent part dimensions.
By addressing these factors, manufacturers can significantly reduce the occurrence of material shortages and improve the efficiency and quality of their plastic injection molding processes. Dongguan Hengrong Machinery Co., Ltd. continues to support customers with expert advice and advanced solutions tailored to their specific needs.
