What impact will the number of injection mold trials have?

1. The design of the injection mold did not go through a full collective review. The structure of the injection mold was unreasonable, which caused the injection mold to undergo multiple improvements after the test, which caused the injection mold cost to exceed the budget.


If it can be solved after several improvements, it is relatively fortunate. In many cases, it is unsatisfactory. Even if the injection mold is to be scrapped and redone, this cost cannot be controlled. There are also cases where the design of the injection mold is good, but the processing of the injection mold is not in place, which makes the number of trials increase unreasonably, directly increasing 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 optimal molding process and model of the injection molding machine were not selected during the mold test. The injection mold is obviously very good, but the injection molded product is not ideal. The number of trials is increased for no reason, which directly increases the cost of injection molds. This is a common problem in some small injection mold factories.


3, do not fully understand the physical properties of plastics, and even the shrinkage rate is not accurate, such situations often occur. Therefore, before designing the injection mold, it is necessary to understand the physical properties of the plastic to effectively reduce the number of trials.
