Why Do Injection Molds Need To Be Tested
Apr 24, 2022
Most of the defects of injection molding products are caused in the plasticizing and injection molding stage of the injection mold, but sometimes it is also related to the unreasonable design. The influencing factors include: the type of injection port, the number of mold cavities, the location and size, and the cold/hot runner system. design 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 getting the test results of the injection mold, the operator usually needs to re-evaluate the specific conditions of the mold, so as not to increase the 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 incorrect settings without knowing it, because the parameter setting range required to produce a qualified product is very small, once any deviation in the parameter settings may occur. Will result in the quality of the final product far beyond the allowable error range.
The purpose of injection mold tryout is to find out the optimized process parameters and mold design, not just to get a good sample, which is very important.
