1: After long-term use of the mold, the cutting edge must be ground, and the cutting edge surface must be demagnetized to avoid magnetism, otherwise it is prone to material blockage.

2: Elastic components such as springs are most susceptible to damage during use, often resulting in breakage and deformation. The method adopted is replacement. During the replacement process, it is necessary to pay attention to the specifications and models of the spring. The specifications and models of the spring are confirmed by three items: color, outer diameter, and length. Only when all three items are the same can it be replaced.

3: During the use of molds, the punch is prone to breakage, bending, and gnawing, and the punching sleeve is generally gnawed. The damage to the punch and punch sleeve is usually replaced with parts of the same specifications. The parameters of the punch mainly include the working part size, installation part size, length size, etc.

4: Tighten the parts and check if they are loose or damaged. The solution is to replace them with parts of the same specifications.

5: Pressing parts such as pressing plates, Yuli glue, etc., unloading parts such as stripping plates, pneumatic top material, etc. During maintenance, check the relationship between the accessories in each part and whether there is any damage. Repair the damaged parts, check for air leakage in the pneumatic top material, and take measures for specific situations. Replace if the trachea is damaged.
