We all know that the quality of SMC parts depends on factors such as the press equipment, mold, technical parameters, and workforce quality. If any aspect is done poorly, it cannot produce high-quality SMC molds. At this point, it tests the enterprise, how to improve the quality of SMC products? There are definitely methods. Let's take a look together.
Superior performance of SMC molds
The production characteristics and information application status of SMC molds. SMC molds have superior corrosion resistance, light weight, easy engineering design, and flexibility. Its mechanical properties can be comparable to some metal materials. The products manufactured by SMC molds have good rigidity, deformation resistance, and a broad range of use temperatures. SMC molds are materials that have excellent electrical performance, corrosion resistance, light weight, easy engineering design, and flexibility. Its performance is similar to that of metal, so it is widely used in electric meter box molds, automobile molds, and so on.
SMC composite molded fiberglass cable tray is a new type of trough cable tray. Compared with the iron trough cable tray, the SMC composite molded fiberglass cable tray has the advantages of long service life (generally designed for 30 years), convenient installation, low cost (only 1/4 of the weight of carbon steel, without hot work during construction), no maintenance, high strength, good insulation performance, and chemical resistance. The production process of SMC composite molded fiberglass cable tray uses SMC composite material molding process for production. The main raw materials are GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler), and various auxiliaries. The SMC composite material molding process is the most efficient production process in the fiberglass composite material molding process.
Methods to improve the quality of SMC molds
To improve the quality of SMC molds products, it is necessary to focus on the press equipment. SMC products have extremely strict requirements for the press. The pressure applied to the product during molding is about 50 to 100 kg/cm². Therefore, the smaller the area of the product, the less pressure it requires. Parts with larger areas, such as waterproof trays, wall panels, bathtubs, roof panels, etc., require the press with higher pressure. The molding technology of SMC components is also critical. All aspects of the produced products must be clear. The requirements for the speed of the press slider's up-and-down movement and mold precision are also high. The pressure, temperature, and even the pressure that opens and closes the mold in each area of the produced mold must be uniform and precise.
