After the mold is used for a long time, the cutting edge must be sharpened. After grinding, the cutting edge surface must be demagnetized, and it must not be magnetic, otherwise it will easily block the material. The mold manufacturer must make detailed records, count its use, care (lubrication, cleaning, rust prevention) and damage, and thus find out which parts and components have been damaged and the degree of wear and tear to provide information for discovering and solving problems. And the molding process parameters of the mold, the materials used in the product, in order to shorten the test time of the mold and improve the production efficiency. The various properties of the mold should be tested under the normal operation of the injection molding machine and the mold, and the size of the final molded plastic part should be measured. Through this information, the existing state of the mold can be determined, and the cavity, the core, the cooling system and the cavity can be found. The damage of the parting surface, etc., according to the information provided by the plastic parts, can determine the damage state of the mold and maintenance measures.
 Springs, such as springs, are most susceptible to damage during use, and are often broken and deformed. The method adopted is to replace. In the process of replacement, we must pay attention to the specifications and models of the spring. The specifications and models of the spring are confirmed by the color, outer diameter and length. Only when all three items are the same can be replaced. The spring is made of imported quality, and the famous brand has Raymond mold spring.
