Strengthen the training of scientific injection molding knowledge and try not to damage the molds during production. Improper parameters such as low-pressure protection Settings, mold closing speed, clamping force, injection speed, holding pressure, and mold temperature can all cause significant damage to the mold.

2. Production control. Incidents like the hot runner iron jamming and PIN jamming that damage the mold as shown in the table should be avoided as much as possible.

3. Problems in the womb should be avoided. The design and manufacturing process of plastic mold processing is like "gestation". At this stage, problems cannot exist; otherwise, maintenance is inevitable. For instance, the design and materials of the seven major systems of the mold will not be elaborated one by one.

4. Mold maintenance. During regular production, the first and second-level maintenance and the third-level maintenance in the mold repair department must be solid and thorough. Things like wire drawing, dust and sharp edges should be avoided, as well as spring breakage, ejector pin jamming, and punctures caused by chicken scraping. Injection mold

5. Standardization and inventory of vulnerable parts. The ejector pins, springs, bushings, guide pins, guide sleeves, etc. should be of uniform specifications as much as possible and kept in stock.

6. Standardization of operation processes, personnel training and performance assessment.
