How to do quality inspection for plastic mould?

Plastic products to do well, all rely on the plastic mold “support.”. With the development trend of industrialization, the application of plastic mold has been everywhere. In the production process of plastic products, the quality of plastic molds determines the quality of finished products. Therefore, the practical significance of plastic molds for plastic products is of course obvious. Generally, the cost of plastic mold customization is high, and the quality of plastic mold is related to whether the mass production can be carried out smoothly. This puts forward higher technical standards for plastic mold materials. So what kind of testing index should the plastic mould achieve?
The new inspection items of plastic mould generally include specifications and dimensions, appearance design, weight, chemical composition analysis, strength, nonmetal material parameters, ultrasonic testing, process performance, grain size, unique chemical composition and other indicators. Natural different types of plastic mold, the actual test index is still different. For example, in the “chemical composition analysis” item, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and copper are key elements for non carbon steel, while carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, nickel, vanadium, copper, hydrogen and other elements are detected for pre hardened round steel, and the contents of carbon, silicon, copper, chromium, molybdenum, nickel and vanadium in corrosion-resistant steel are detected.

The machinability, machinability and quenching of plastic mould are the key properties to consider its quality. The content of residue is very harmful to the steel structure. Therefore, the new test items such as nonmetallic material parameters and grain size can reflect the processability of plastic mold. However, ultrasonic testing can detect the internal defects of plastic mold, and there is a certain connection for hardenability. For the plastic mold quenching force is of course the strength index test, the natural carbon content is also directly related to the quenching force.
