Why do plastic molds for injection molded parts have to be tested?

The disadvantages of injection molded products are caused during the plasticization and injection molding stages of injection molds, but sometimes they are also related to unreasonable design. Influencing factors include: type of injection port, number of plastic mold cavities, location and size, cold/warm runner system design and the structure of the product itself. Therefore, in order to avoid product defects caused by plastic mold design, mold manufacturers need to analyze the plastic mold during manufacturing. After obtaining the mold trial results of injection molded parts, the operator usually needs to re-evaluate the specific conditions of the mold, so as to avoid adding unnecessary costs and time during the correction process.

In most cases, in order to compensate 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, maybe It will cause the quality of the final product to far exceed the allowable error range. The purpose of plastic mold trial for injection molded parts is to find out the optimized process parameters and mold design. And not just to get a good sample. This is very important.

Even if factors such as materials, machine settings, or the environment change, a stable and uninterrupted mass production environment can still be guaranteed.
