There are very few reasons why plastic mold maintenance actually comes from the mold itself. Although it is a small probability, we also need to pay attention to the root cause of mold maintenance from the source.

1. Strengthen scientific and reasonable injection molding knowledge training, try not to damage the mold during production, and set low-voltage protection. Improper parameters such as mold clamping speed, clamping force, injection speed, holding pressure, and temperature will greatly damage the mold, which requires great attention.

2. In production control, the glue inlet and hot runner plugging should be avoided.

3. Mold maintenance, thimble card, spring breakage, and wire drawing dust should be avoided.

4. The corresponding quantity of wearing parts must be prepared in the warehouse, such as: thimbles, springs, cylinders, guide posts, etc., should be of uniform specifications and kept in stock.

5. Operation specifications for injection molding production personnel.

When the above points are done well, the maintenance of the mold can be greatly reduced, so these points are also the premise of making a set of molds.
