The choice and requirements of materials, for the Laboratory Plastic Ware Mould , is related to the quality of the product, so Yuhuan Shengjiu Mould Co , Ltd. is engaged in the topic of plastic mold materials, 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.
