When manufacturing detection accessory A, what factors should be considered in the selection of injection mold materials?

When manufacturing detection accessory A, the selection of injection mold materials is an important link, which is directly related to the quality of the product, production efficiency and the service life of the mold. As a detection plastic part, detection accessory A needs to have a certain strength and hardness to ensure that it is not easily deformed or damaged during the detection process. Therefore, the mold material should have the corresponding strength and hardness to produce plastic parts that meet the requirements. PC/ABS materials have certain chemical stability, but the mold material still needs to consider the compatibility with the injection molding material to avoid chemical reactions under high temperature and high pressure, resulting in mold surface corrosion or plastic performance degradation.
The mold hardness determines its ability to resist deformation and scratches. For materials such as PC/ABS, insufficient mold hardness can easily cause surface scratches, so a mold material with higher hardness needs to be selected. The mold needs to remain stable during high-pressure injection molding, so the material needs to have sufficient strength. When the mold is impacted, good toughness can prevent it from cracking or breaking.
The mold needs to have a certain corrosion resistance to resist corrosive substances that may be generated during the injection molding process. In the high temperature and high pressure injection molding environment, the mold material should maintain good oxidation resistance to avoid performance degradation.
The machinability, polishability, weldability and heat treatment performance of the mold material all affect its processing efficiency and cost. Easy-to-process materials can shorten the mold manufacturing cycle and reduce processing costs. When selecting mold materials, it is necessary to comprehensively consider the balance between performance and cost. High-performance materials are often accompanied by higher costs, but in the long run, high-durability materials can reduce the frequency of mold replacement and maintenance costs.
Complex mold structures require materials with good toughness and fatigue resistance to cope with complex stress conditions. The service life of the mold directly affects production efficiency and cost. Therefore, it is necessary to select materials with high durability to reduce the frequency of mold replacement and maintenance.
With the increase of environmental awareness, the selection of mold materials also needs to consider their environmental protection and sustainability. Giving priority to recyclable, degradable or environmentally friendly materials is not only in line with corporate social responsibility, but also conducive to the long-term development of the enterprise.
