the test mold reason of injection plastic mold
Defects in most injection molding products are caused during the injection molding and injection stages, but are sometimes related to design irregularities. Factors include: type of injection port, number of mold cavities, location and size, design of cold/hot runner 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 test results of the injection mold, the operator usually needs to re-evaluate the specific conditions of the mold to avoid adding unnecessary cost and time in the process of modification.
In most cases, in order to make up for its deficiency in die design, the operator may be unwittingly made incorrect Settings, because the parameters required for the production of qualified products range is very small, once there's any deviation in parameter Settings, may lead to the final product quality far beyond the allowed error range
The purpose of injection mold testing is to find out the optimized process parameters and mold design.
Not just to get a good sample. A stable and continuous mass production environment can be ensured even when material, machine Settings or environmental factors change.
