The choice and requirements of materials, for plastic molds, is related to the quality of the product, so today, we are focusing on the materials of plastic molds, bringing you detailed analysis.
The material requires that the working condition of the plastic mold is different from that of the cold die. Generally, it must be operated at 150 °C-200 °C. In addition to being subjected to a certain pressure, it must also withstand the temperature influence. According to the different conditions and processing methods of plastic molding dies, the basic performance requirements of steel for plastic molds are roughly summarized as follows:
With the development of the plastics industry, the complexity and precision of plastic products are becoming more and more demanding, and higher requirements are also placed on the mold materials. For the production of complex, precise and corrosion-resistant plastic molds, pre-hardened steel (such as PMS), corrosion-resistant steel (such as PCR) and low-carbon maraging steel (such as 18Ni-250) can be used. Machining, heat treatment and polishing performance and high strength.
In addition, when selecting materials, it is necessary to consider preventing scratches and gluing. If there is relative motion between the two surfaces, try to avoid selecting materials with the same structure. In special cases, one side may be plated or nitrided to make the two sides different. Surface structure.
