The SMC insulator is a high-strength, high-insulation, lightweight insulating material. It is primarily composed of quartz, glass fiber, and other materials combined with resin. It finds extensive app...
SMC molds are one of the main tools for producing SMC products. SMC has various uses and can be used in residences, workplaces, and roads, among other fields. If the glass fiber material is combined correctly with resin under suitable conditions and at a sufficient temperature, it has high plasticity, i.e., the kind of fluidity required for mold production. When the temperature of the resin and fiber decreases, it becomes exceptionally sturdy. The strength of the glass fiber and resin composite is high because of the high-strength characteristics of the glass fibers, making it ideal for doors, ships, and storage of heavy materials.
To produce SMC molds, a master mold, i.e., a sample product, is required. The master mold is an accurate replica of the desired product. The rubber layer made on the mold can be used on the master mold, and it is essential to apply a layer of lubricant when finishing the production, which can help the mold smoothly release from the master mold. Usually, these lubricants are some waxy substances and sometimes other materials are also used as lubricants. After the mold is released, wax-like lubricants pose minimal harm to it.
Modern technology for SMC mold testing
The SMC molding process is an advanced composite material forming technology, and the mold is the foundation of producing a product. The same goes for the SMC process, and the quality of the product is provided by reliable molds. Therefore, in the design of the SMC molding process, the design of the SMC mould is critical. Starting from the best aspects of the mold's slope design, trimming edge design, ejection system, corner design, and heating mode determination, it basically covers the key control points of the SMC mold's design for non-mold manufacturers. In addition, the appropriate materials should be determined according to the product's requirements for surface quality and required quantity. The development of precision molds has raised the requirements for the testing level of SMC molds. For a long time, the most accurate three-coordinate measuring machine has rarely been used in production due to the limitations and impact of the environment. The latest three-coordinate measuring machines mostly have temperature compensation and adopt anti-seismic materials, which improves dust resistance and environmental adaptation and reliability, making it possible to install them in workshops and achieve on-site measurement.
Surface treatment of oil heater mold for SMC mold
In addition to requiring the mold body to have a reasonable match of sufficient strength and toughness in work, its surface performance is essential to the mold's working performance and service life. These surface performance probably includes wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc. The improvement of most performance solely depends on the improvement and enhancement of the substrate material, which is very limited and uneconomical. Moreover, through the surface treatment technology, often they can achieve twice the result with half the effort. The SMC mould's surface treatment technology changes the surface of the mold through surface coating, surface modification, or composite treatment technology, to obtain the desired surface performance's systematic engineering, including chemical methods, physical methods, physicochemical methods, and mechanical methods.
