What kind of plastic furniture molds can be called high-quality molds? In fact, it is not difficult to find the answer. The value of the mold is to achieve efficient mass production of high-quality products. High efficiency and high quality are the key factors for inspecting the mold. We cannot see the quality of plastic molds with our eyes. For example, improper mold design of plastic furniture products often causes one or another defect in the final product. These problems cannot be completely avoided before manufacturing; in the manufacturing process Inevitably, some sizes are not processed locally or some functions are omitted.

According to the movement of mold and injection parts, analyze, evaluate, modify and optimize the mold to meet the high quality requirements of mass production. Most of the defects of mold products are caused in the plasticizing and injection stage, but sometimes it is also related to the improper mold design of plastic furniture products. Possible influencing factors include: the number of molds, the design of the cold/hot runner system, the type, location and size of the injection port and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, it is necessary to analyze the mold design and process parameters when manufacturing the mold.

After obtaining the test results, the operator usually needs to evaluate the specific conditions of the plastic furniture product mold to avoid unnecessary cost and time in the process of modifying the mold. In most cases, the evaluation also includes the setting of machine process parameters. In other words, in order to make up for the shortcomings in the mold design, the operator may make incorrect settings without knowing it. In this case, since the range of parameters required to produce qualified products is very small, the production and operation of the equipment is abnormal. When there is a slight deviation in the parameter setting, the quality of the final product may far exceed the allowable range of the error, and the actual production cost resulting from this is higher than the preset cost. The cost of plastic furniture mold optimization is much higher.

The purpose of the plastic furniture product mold test is to find out the optimized process parameters and mold design. In this way, even if factors such as material, machine settings or environment change, a stable and continuous mass production environment can be guaranteed, not just to obtain a good sample. This is important.
