Will the injection mold be put into production immediately after completing? The answer is of course no, because there is still a very important part-trial test. The trial mold is an indispensable part, and the result of the trial mold will directly affect the follow-up production of the factory.
Why do a trial?
Whether the plastic mold is easy to inject or not can't be seen with the eyes. Generally speaking, the mold is not directly used as a product when it is designed, because it will have one or another defect after production. We need to pass the trial test, and then analyze, evaluate and optimize the samples produced by the trial test to meet high quality requirements. However, most of the defects of molded products are caused during the plasticization and injection molding stages, and may also be caused by improper manufacturing of plastic molds. Therefore, in order to avoid product defects caused by mold design, it is necessary to analyze mold design and process parameters during mold manufacturing.
What are the consequences of many trials?
Although the process parameters and mold design of the injection mold can be optimized, it will also increase the production cost of the injection mold. If the structure of the injection mold is found to be unreasonable after the mold trial, the injection mold must be improved, which will undoubtedly make the injection cost exceed the budget.
How to reduce the times of trial?The number of mold tests for a mold depends on the following points:
1. Whether the optimization of customer product structure is perfect.
2. Is the evaluation of mold drawings perfect?
3. Whether the processing arrangement of mold parts is reasonable.
4. Whether the mold processing process control is appropriate.
5. Whether the scientific trial test is effective.
6. Whether the improvement plan for the trial mold problem is strict and effective.
By doing the above 6 points, I believe we can greatly reduce the number of mold tests and the production cost of injection molds
