The main raw materials are composed of SMC special yarn, unsaturated resin, low shrinkage additives, fillers and various additives. It first appeared in Europe in the early 1960s. Around 1965, the United States and Japan developed this technology one after another. In the late 1980s, my country introduced advanced foreign SMC production lines and production techniques. SMC has the advantages of superior electrical performance, corrosion resistance, light weight, easy and flexible engineering design, and its mechanical properties are comparable to some metal materials, so it is widely used in transportation vehicles, construction, electronics/electrical and other industries.
Application of SMC mold:
1. Application in the automotive industry
Suspension parts, front and rear bumpers, instrument panels, etc.;
Body and body parts, hard shell roof, non-slip floor, spoiler, sun hood, engine cover;
Lower parts of the engine cover, air guide cover, intake pipe cover, fan guide ring, engine sound insulation board;
Interior decoration parts: door handle, instrument panel, steering rod parts.
2. the application of railway cars
Seat, coffee table and countertop;
Railway vehicle window frames, carriage wall and roof panels, railway signal transponders.
3. Application in electrical and communication engineering
Electrical appliance cover: electrical switch box, electrical wiring box, cable distribution box shell, terminal distributor;
Electronic engineering application: antenna reflector, radome, printed circuit board;
Electrical components: insulators, insulating operating tools, motor commutators;
Communication equipment applications: telephone shells, cable distribution boxes, telephone booths.
4. Application in construction projects High-rise roof water tanks and purification tanks
Shower supplies: such as bathtub, sink, waterproof tray, toilet;
Building template, storage room components: such as siding, roof, door frame.
5.other

Packaging, transportation, storage
SMC series molding compound is packaged in a composite film bag, each package is about 50 kg, and packed into a carton;
The storage period is in a dry warehouse where the temperature is lower than 25°C and protected from sunlight. Three to six months from the production date, it can still be used after the storage period has passed.
