During the use of tens of thousands of injection molds, problems will inevitably occur. However, the problem is that the number of mold repairs should be shortened as much as possible, which can greatly reduce maintenance costs and improve production efficiency.
During the use of tens of thousands of injection molds, problems will inevitably occur. However, the problem is that the number of mold repairs should be shortened as much as possible, which can greatly reduce maintenance costs and improve production efficiency. Ideally, mold has a design life of 300,000 beer, and large maintenance of 50,000 beer. During the production cycle, except for the spring thimble rubber ring of the consumables, other components do not need to be replaced. But in fact, the general mold is repaired and repaired, and even a set of production molds will be repaired 2-3 times a month. In fact, most repairs to the mold can be avoided, with maintenance issues and production process control issues. The following table is an analysis of the mold maintenance history of a company.
