How to judge the mold needs to be repaired or replaced

Update: 03-12-2021

The first step is to solve the mold condition. This can be done by Cap mould visual inspection of the mold and its parts. Over time, dimensional inspection of parts is also important to consider potential wear areas, which usually vary according to the type of material being processed. Compared with other materials, the mold wear rate of glass-filled materials is much faster. Unfortunately, any place where the material flows will eventually wear out. Although it is sometimes difficult to see, the tool surface wear will be revealed by detailed dimensional inspection in the component parts. The mold you initially build will likely last long enough to meet your production needs.


If your project is becoming obsolete, it is best to perform minimal maintenance on the mold. On the other hand, if your project is growing, it is a good opportunity to re-evaluate the entire project. If your project is growing, you may want to consider building higher cavitation tools. If you start with a two-cavity mold, switching to a four-cavity mold may save a lot of cost. In some cases, the cost savings can generate a return on investment within a year. New design tools also give you the opportunity to update or optimize part designs. Design changes such as reducing wall thickness, changing gate design, and increasing cooling capacity can also save costs in the long term.


For more complex molds that use hydraulic systems, unscrewing cores, and other types of actions, it becomes more important to resolve potential failure points before the mold reaches the end of its useful life. . Your mold maker should be able to disassemble the mold, check the dimensions and inspect your mold. From there, they should be able to tell you some potential wear points and provide advice on proactive maintenance. More complex molds are unlikely to be economical to replace.


However, with proper maintenance and some planning, a well-built 101 or 102 mold can far exceed cycle expectations. At a certain stage in the life of a mold, the time required to rework the mold, replace parts, and repair damage is not worth the investment at all. Finally, injection molds are an asset of your company, which is producing the products needed to operate the business. Ensuring that the mold performs well and does not fail completely is essential to avoid downtime and keep the supply chain running. The following are some signs that molds require special attention. If you find that there are multiple or all of these problems, it may be time to consider replacing the mold completely.
