When the mold is damaged, whether to choose to scrap it directly or repair the mold, this needs to be carefully selected!

First of all, we need to take into account the high cost of molds produced by injection molding. Usually mold costs account for about a quarter of the total cost of the parts, mainly because mold manufacturing is difficult and costly, and mold repair and maintenance after weapons are put into production. The cost should not be underestimated, and the cost of the mold may only account for about 40% of the entire mold cost. Therefore, if the mold can be repaired in time, the mold cost for injection molding can be greatly reduced to a certain extent.

After the mold is damaged, it faces the problem of repair or scrap. The unnatural wear and tear of the plastic mold fails, such as the destruction of non-critical parts. And failures such as damage to small parts. Most of them can be completely restored to a producible state through maintenance and re-invested in injection molding production. However, when the key parts of the mold are severely damaged, the front mold and the back mold are damaged at the same time. The one-time repair cost exceeds 70% of the original cost of the mold or the mold life is near. Then such maintenance is of little significance. It should be considered to scrap this set of molds.

Except for large molds, molds with complex structures. When the mold repair technology is too complicated, the repair cost is too large, and the difficulty will inevitably make the repair cycle too long, which will seriously affect the normal production of injection molding. At this time, it is necessary to increase the selection of failure and scrap, and re-manufacture the mold.

Injection molding production efficiency and cost are highly dependent on the mold. In the production process, the failure of the mold should be analyzed in detail and the correct maintenance plan should be formulated. Solve problems such as mold damage, card mold and product quality defects in time. Dealing with the relationship between mold maintenance and scrapping can reduce the shutdown time for maintenance, shorten the production cycle, and ensure the normal progress of injection molding production.
