Lack Of Materials In The Plastic injection molding
2023-12-07
Plastic injection molding products are very common in life, but when using injection molding machines to produce these injection parts, they often encounter defective products. Today, it is simple to say if there is a lack of Materials in the mold products. Consider the following solutions: 
1. Check mold design and manufacturing: First of all, check whether the design and manufacturing of the mold meet the product requirements. Ensure that the mold has a suitable runner track design, the correct size and shape to ensure that the plastic material can fully fill the mold cavity. 2. Adjust the injection molding process parameters: check the injection molding process parameters, such as injection pressure, injection speed, pressure holding time, etc. According to the material characteristics of the product and the mold structure, these parameters are appropriately adjusted to promote the full filling of the plastic material and reduce the occurrence of the lack of materials. 
3. Check the properties of the plastic material: ensure that the selected runner meets the product requirements and has good fluidity. If the viscosity of the compound is too high or the fluidity is poor, it may lead to a lack of glue. When selecting the compound, consider its melting temperature, viscosity range and flow properties to ensure that it is suitable for the mold and injection molding process used. 4. Repair mold problems: If the mold has problems such as damage, wear or fatigue, it may cause the plastic material to be unable to fully fill the mold cavity, resulting in a lack of glue. When mold problems are found, timely repair or replace the mold to ensure its normal operation. 5. Optimize product design: By optimizing product design, such as increasing channels, changing product size or shape, etc., the plastic material can flow more smoothly and fill the mold cavity, reducing the possibility of lack of material. 6. Strengthen quality control: Establish a sound quality control system, including strict raw material inspection, injection process monitoring and product testing. Ensure that each process complies with the requirements to reduce the occurrence of material shortage problems. If the above methods still cannot solve the problem of lack of material, it is recommended to consult a professional injection molding engineer or technical personnel. They can conduct detailed analysis and evaluation and provide targeted solutions.
