1: After the mold is used for a long time, it must be sharpened. After grinding, the edge surface must be demagnetized, and it must not be magnetic, otherwise the material may be easily blocked. The mold use company needs to make detailed records, statistics its use, care (lubrication, cleaning, rust prevention) and damages. According to this, it can discover which parts and components have been damaged and the degree of wear is large enough to provide information for finding and resolving problems. And the molding process parameters of the mold, the materials used in the product, to shorten the test time of the mold, improve production efficiency. Should be in the normal operation of the injection molding machine, mold, test the various properties of the mold, and the final molded plastic part size measurement, through the information can determine the current state of the mold, find the cavity, core, cooling system and The damage of the parting surface, etc., according to the information provided by the plastic parts, can determine the mold damage status and maintenance measures.

2: Springs and other elastic parts in the use of the most vulnerable to damage to the spring, usually the phenomenon of fracture and deformation. The method adopted is replacement. During the replacement process, attention must be paid to the specification and model of the spring. The specification and model of the spring are identified by the color, outer diameter, and length. Only when all three items are the same, can they be replaced. The quality of the spring is better for the import.

3: The punch is prone to breaking, bending and smashing during the use of the die. The punching sleeve is generally damaged. Damage to punches and bushings is generally replaced with parts of the same specification. Punch parameters mainly include working part size, mounting part size, and length dimension.
