what is thermoset moulding? Thermoset molding is an irreversible molding process through which plastic forms of plastics are pressed into heated molds and form their final shape. Thermosetting materials are usually stronger than thermoforming materials and are also more suitable for high-temperature applications. This is because the catalyst added to the base compound causes chemical reactions at the molecular level to form a hard, irreversible final product. Thermoset plastics can not be remelted and can only be ground and recycled as fillers for different applications.
Thermoset molds are mainly used for forming thermoset plastic products, that is, processing and forming powdered thermoset plastics. Types include thermoset compression mold, thermoset transfer mold and thermoset injection mold. Among them, compression molds are the most used, and injection molds are less. There is no gating system in the thermoset mold, and there is a cavity or feeding chamber as the space to accommodate the forming material, and the material is preheated. The forming pressure is directly applied to plastic parts by die, which is suitable for plastics with poor forming fluidity or various fillers. And the orientation of the plastic parts is less, the orientation degree is low, and the performance of each direction is more uniform.
As a custom thermoset mold supplier, MDC Mould provide thermoset molds manufacturing and thermoset molding services such as phenolic resins, BMC, DMC, SMC and epoxy resins. Large, multi-cavity, high-quality thermoset molds are one of our unique core competencies.
MDC have 500 to 4000 tons of thermoset molding machine that enable us to make various thermoset parts. MDC thermoset molding parts are used in various products that need to protect them from high temperature, corrosion, and electrical environment, as well as exposure to chemicals or fluids, to achieve lightweight requirements, and to reduce costs and save time for product assembly.
