About plastic mold repair and maintenance About the maintenance of plastic molds can improve the service life and accuracy of plastic molds, and generally do not take maintenance. In the factors affecting the service life of the mold, the use and maintenance accounted for 15%-20%, the service life of the injection mold can reach 800,000 times under normal circumstances, and those well-maintained molds can be extended by 2-3 times. Not paying attention to maintenance, the service life of injection molds is generally short, so it is very important to maintain the mold. Maintenance and repair of plastic molds We have to do the following requirements: standardize cap mould/mold factory the production of molding.

The molding production personnel must have a full understanding of the characteristics of the plastic and the structure of the mold, so that the molding machine corresponding to it can be correctly selected and the low-pressure closed mold, high-pressure mold clamping and molding process conditions can be reasonably adjusted, and the molding die and molding can be performed. The equipment and the molding operation process are subject to necessary management; the maintenance and repair of the mold must be timely, correct and standardized. Once the plastic mold is found to be faulty, it should be repaired in time. If the small problem is not solved, it will often cause big problems. First, we should find the cause of the failure, and then develop a correct repair plan after considering this comprehensively. In the selection of the repair plan, a comprehensive, high-quality, efficient and economical solution should be selected for the maintenance and repair of the mold.

For the daily maintenance of plastic molds. In the ordinary production process, the maintenance of the mold should also be done well. In the maintenance process of the plastic mold, the surface of the cavity is the most important, and the roughness requirement of the surface of the cavity must be ensured, while the need for demoulding is satisfied. It is also not possible to have scratches. It should be cleaned regularly and rust-proofed. A certain amount of lubricating grease should be added to the sliding parts in the mold to ensure flexible starting, and the wearing parts of the mold should be replaced at the right time.
