Quality Control And Inspection Methods for Mold Processing

The quality control and inspection method of mold processing is an important link to ensure mold accuracy and product quality. In the mold processing process, quality control and testing throughout, from the selection of raw materials, the control of the processing process to the detection of the final product, all need to carry out strict quality management.

In terms of quality control, we must first ensure that the quality of raw materials meets the requirements. In the procurement process, the supplier's materials should be strictly screened and inspected to ensure that the quality, performance and specifications of the materials meet the design requirements. At the same time, in the process of processing, processing equipment and tools should be regularly maintained and checked to ensure its accuracy and stability. In addition, the process parameters should be strictly controlled during the processing, such as cutting speed, feed rate, cutting depth, etc., to ensure processing accuracy and surface quality.

In terms of inspection, a variety of methods can be used to ensure the accuracy and quality of the mold. Among them, coordinate measurement is one of the most commonly used detection methods. The CMM can accurately measure the size, shape and position of each part of the mold, and has the advantages of high precision and fast efficiency. In addition, the appearance inspection is also one of the important detection means, mainly to check the mold surface defects and damage, such as cracks, oxidation, scratches and so on. Appearance inspection can intuitively determine whether the mold surface meets the requirements, for high requirements of the mold, but also need to use magnifying glass and other equipment for detailed observation.

In addition to the above two detection methods, there are dimensional measurement, material performance testing and other methods. Dimensional measurement includes the use of measuring tools (such as micrometers, vernier calipers, etc.) to measure the external dimensions and internal dimensions of the mold to ensure that it meets the design requirements. The material performance test mainly tests the mechanical properties of the mold material, such as hardness, strength, toughness, etc., to ensure that the material meets the requirements of use.

In summary, the quality control and inspection method of mold processing is the key link to ensure mold accuracy and product quality. Through strict quality control, reasonable processing technology and effective testing methods, high-quality molds can be manufactured to provide a strong guarantee for the manufacture of products.
