Why must try to die?

Improper mold design tends to cause the final product. One way or the other defects. So, before the mold modification, usually need to test and evaluation, optimization of mold design and process parameters, so as to avoid unnecessary error, and achieve twice the result with half the effort, can satisfy the demands of mass production of high quality at the same time. Most of the forming defect of the products is in the plasticization and injection stage, but sometimes also is associated with improper mould design, possible influence factors include: cavity number, cold/hot runner system design, into the mouth of the type, location and size, and the structure of the product itself. Therefore, in order to avoid the defects caused by mold design products, we need at the time of making mould, the mould design and process parameters are analyzed. After get the test results, the operator usually need to assess the specific circumstances of the mould, in order to avoid in the process of modify mould increase unnecessary costs and time. In most cases, this kind of evaluation include the machine process parameters setting. That is to say, in order to make up for its deficiency in die design, the operator may be unwittingly made incorrect Settings. In this case, the equipment of the production process is not normal, because the parameters required for the production of qualified products range is very small, once the parameters set any tiny deviation, may lead to the final product quality far beyond the allowed error range, and the resulting actual production costs than mould optimization in advance the cost much higher. The purpose of test is to find out the optimized process parameters and die design. In this way, even if is to set or environmental factors such as material, the machine has changed, is still able to ensure stable and uninterrupted production environment, and not just to get a good sample. This is very important.
