1. The processing enterprise should first equip each pair of injection molds with a resume card to record and count its use, care (lubrication, cleaning, rust prevention) and damage in detail. Based on this, it can be found which parts and components are damaged and the degree of wear and tear. In order to provide information on finding and solving problems, as well as the molding process parameters of the injection mold and the materials used in the product, in order to shorten the test run time of the mold and improve production efficiency.

2. The processing enterprise should test the various properties of the injection mold under the normal operation of the injection molding machine and the mold, and measure the size of the later molded plastic part. Through this information, the existing state of the mold can be determined, and the cavity, The damage of the core, cooling system and parting surface, etc., can be judged according to the information provided by the plastic parts, and the damage status and maintenance measures of the mold can be judged.
3. Pay attention to the surface maintenance of the injection mold, which directly affects the surface quality of the product, and the focus is on preventing rust. Therefore, it is particularly important to choose a suitable, high-quality and professional anti-rust oil. When the mold completes the production task, different methods should be used to carefully remove the residual injection molding according to different injection molding methods. Copper rods, copper wires and injection mold cleaning agents can be used to remove residual injection molding and other deposits in the mold, and then air dry.
