Improper mold design often leads to defects of one kind or another in the final product. Before modifying the mold, try out the mold and evaluate it first, optimize the mold design and process parameters, usually can achieve twice the result with half the effort, and at the same time meet the high-quality requirements of mass production.
Why do you have to try out the model?
Most of the defects of molded products are caused during the plasticization and injection molding stages, but sometimes they are also related to improper mold design. Possible influencing factors include: number of mold cavities, design of cold/hot runner system, type, location and location of injection ports. size, and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, we need to analyze the design and process parameters of the mold when making the mold.
After obtaining the results of the mold trial, the operator usually needs to evaluate the specific conditions of the mold to avoid unnecessary cost and time in the process of modifying the mold. In most cases, this evaluation also includes setting the process parameters of the machine. That is to say, in order to compensate for the deficiencies in the mold design, the operator may make incorrect settings without knowing it.
In this case, the production operation process of the equipment is not normal, because the parameter setting range required to produce a qualified product is very small, and any slight deviation in the parameter setting may cause the quality of the final product to far exceed the allowable The error range, and the resulting actual production cost is much higher than the cost of mold optimization in advance.
The purpose of mold trial is to find out the optimized process parameters and mold design. This ensures a stable and uninterrupted mass production environment, not just for a good sample, even if factors such as materials, machine settings, or the environment change. this point is very important.
