Most of the defects of injection molded products are caused during the plasticizing and injection molding stages of the injection mold, but sometimes they are also related to the unreasonable design. The influencing factors include: the type of injection port, the number of mold cavities, position and size, and cold/hot flow. The design of the road system and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, we need to analyze the injection mold during production.

After obtaining the mold trial results of the injection molded part, the operator usually needs to evaluate the specific conditions of the mold to avoid unnecessary cost and time during the modification process. In most cases, in order to make up for the deficiencies in the mold design, the operator may make incorrect settings without knowing it, because the parameter setting range required to produce qualified products is very small. Once there is any deviation in the parameter setting, it may Will cause the quality of the final product to far exceed the allowable error range

The purpose of the injection mold trial is to find the optimized process parameters and mold design. Not just to get a good sample. this point is very important. Even if the materials, machine settings, or environmental factors change, a stable and uninterrupted mass production environment can still be ensured.
