What are the consequences of having more injection mold trials?
- 1. The design of the injection mold has not undergone sufficient collective review, and the structure of the injection mold is unreasonable, so that the injection mold has to be improved many times after the trial, so that the cost of the injection mold exceeds the budget.
If it can be done after several improvements, it is fortunate that there are many cases that are unsatisfactory, and even the injection molds have to be scrapped and redone, this cost cannot be controlled. In some cases, the injection mold is well designed, but the processing of the injection mold is not in place, which makes the number of trial molds increase unreasonably and directly increases the cost of the injection mold. There is no objection to this problem, so many injection mold manufacturers have increased their investment in measuring equipment. - 2. The best molding process and injection molding machine model were not selected during the trial mold. The injection molds were well done, but the products injected were not ideal. Unnecessarily increased the number of trial molds, directly increasing the cost of injection molds. This is a common problem of some small injection mold factories.
- 3. The physical properties of plastics are not fully understood, and even the shrinkage rate is not accurate. Such a situation occurs from time to time. Therefore, before designing the injection mold, it is necessary to understand the physical properties of the plastic in order to effectively reduce the number of mold trials.
Dongguan Injection Mold Factory PTJ Precision is a one-stop plastic injection mold manufacturer with professional injection mold opening, injection, and spraying services.
