What kind of Chair Mould can be called a high-quality mould? In fact, it is not difficult to find the answer. The existence value of the mould lies in realizing high-efficiency mass production of high-quality products. High efficiency and high quality are the key factors for inspecting mould. We can't see the quality of the chair mould with our eyes. For example, improper design of the chair mould will often cause one or another defect in the final product. These problems cannot be completely avoided before manufacturing. In the manufacturing process, it is inevitable that some sizes are not processed in situ or some functions are omitted. According to the movement of the mould and injection moulded parts, the mould is analyzed, evaluated, modified and optimized to meet the high-quality requirements of mass production. The defects of most mould products are caused during plasticization and injection, but sometimes they are also related to the improper design of chair mould. Possible influencing factors include the number of moulds, the design of cold/hot runner systems, the type, location and size of injection ports, and the structure of the product itself. Therefore, in order to avoid product defects caused by mould design, mould design and process parameters need to be analyzed when manufacturing the mould.

After obtaining the test results, the operator usually needs to evaluate the specific situation of the chair mould to avoid adding unnecessary cost and time in the process of modifying the mould. In most cases, the evaluation also includes the setting of machine process parameters. In other words, in order to make up for the deficiencies in mould design, the operator may make the wrong settings without knowing. In this case, the production and operation of the equipment are abnormal due to the small range of parameters required to produce qualified products. When there is a slight deviation in the parameter setting, the quality of the final product may far exceed the allowable error range, resulting in higher actual production cost than the present cost. The cost of chair mould optimization is much higher.

The purpose of testing the chair mould is to find out the optimized process parameters and mould design. In this way, even if factors such as materials, machine settings or environment change, it is very important to ensure a stable and continuous batch production environment, not just to obtain a good sample.
