The defects of most injection molded parts are caused by plasticizing and molding of injection molded parts, but sometimes they are also related to unreasonable design. The influencing factors include: type of injection port, number of mold cavities, position and size, cold/heat flow The design of the 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 at the time of production.
After obtaining the results of the mold test of the injection molded parts, the operator usually needs to evaluate the specific conditions of the mold to avoid unnecessary cost and time in the process of modification. In most cases, in order to make up for the deficiencies in the mold design, the operator may make an incorrect setting without knowing it, because the parameter setting range required to produce a qualified product is very small, and if there is any deviation in the parameter setting, it may be Will result in the quality of the final product far exceeding the allowable error range.
The purpose of mold testing of injection molded parts is to find optimized process parameters and mold design. Not just to get a good sample. this point is very important. Even if factors such as materials, machine settings or the environment change, a stable and uninterrupted mass production environment can be ensured.
