It is necessary to test mold for mold manufacturing. Operators usually need to evaluate the specific situation of the mold, so as to avoid unnecessary cost and time in the process of modification of the mold. The evaluation also includes the setting of machine process parameters. In order to make up for the shortcomings in the mold design, the operator may make incorrect settings without knowing it. The production process of the equipment is abnormal because the parameter setting range required to produce qualified products is very small. Once any slight deviation in the parameter setting may cause the quality of the final product to far exceed the allowable error range, The actual cost of production is often much higher than the cost of optimizing the mold in advance.
Defects of molded products are caused during the plasticization and injection molding stages, but are sometimes related to improper mold design. Possible factors include the number of mold cavities. The design of the cold / hot runner system, the type, location and size of the injection port, and the structure of the product itself. In order to avoid product defects caused by the mold design, we need to make mold design and mold process parameters when making the mold. Perform analysis.
The purpose of the mold test is to find the optimized process parameters and mold design. Even if there are changes in materials, machine settings or the environment, a stable and uninterrupted mass production environment can still be achieved, not only to obtain a good sample. this point is very important.
Basic steps of mold test: set the temperature of the bucket. The initial tank temperature setting must be based on the recommendations of the material supplier. The same material from different manufacturers and different brands may have considerable differences, and the material supplier often has a deep research and understanding of their own materials. Users can make basic settings based on their recommendations, and then fine-tune them appropriately according to specific production conditions.
