SMC Automotive Parts
SMC (Sheet Molding Compound) is a type of sheet molding compound, mainly composed of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler), and various additives. It is pressed into SMC material for automotive parts through heating and pressure.

SMC Fan Casing
SMC fan housing is molded of SMC sheet mold composite materials through high temperature and high pressure molding. Its characteristics include high strength, high hardness, low noise, dimensional stability, corrosion resistance, acid and alkali resistance, aging resistance, and stability of performance without being affected by the external environment, temperature and humidity changes.

SMC Cable Bracket

Step-by-Step SMC Sheet Molding Compound Process

Preparation of Raw Materials
Polyester resin, glass fibers, and fillers are prepared. Additives like curing agents and stabilizers are mixed into the resin to improve properties.

Mixing and Compounding
The resin is mixed with the glass fibers, forming a dough-like consistency. The fiber-resin mix is compressed between two layers of polyethylene film.

Sheet Formation
The mix is rolled into thin sheets, creating the base material for molding.

Maturation
The SMC sheets are stored for 48-72 hours to cure and improve their viscosity.

Cutting
Once matured, the SMC sheets are cut into individual pieces (charges) that will fit into the molds.

Compression Molding
The charges are placed into a mold, and under heat (140-160°C) and pressure (1000-2000 psi), the resin cures and takes the shape of the mold.

Curing and Cooling
After curing, the part is cooled, solidifying its structure.

Trimming and Finishing
Excess material (flash) is trimmed, and the part undergoes finishing processes, such as sanding or painting.

Inspection and Quality Control
The final part is inspected for quality and defects before being shipped out.

FAQ

Q: What is the difference between fiberglass and sheet molding compound?

A: SMC compression molding is created using layers of chopped glass fibers bonded by a resin and polyester mixture. This compound is then shaped using a heated compression process. This product is different from traditional fiberglass products made with a woven or tangled fiberglass body that is then filled in with resin.

Q: Can you use fiberglass resin on SMC?

A: It provides superior adhesion to all types of SMC and fiberglass and part. Provides superior adhesion to SMC panels and is more effective on SMC that other fiberglass-type resins. Must be used with fiberglass mat or cloth. MIXING: Use at temperature of 60°F (16°C) or higher for proper cure.

Q: What is the pressure for SMC molding?

A: SMC molding pressure decided by the product structure, shape, size and SMC thickness. Products with simple shapes only need a molding pressure of 25-30Mpa; for products with complex shapes, the molding pressure can reach 140-210Mpa. The higher the degree of SMC thickening, the greater the molding pressure required.

Q: What is the temperature of SMC molding?

A: SMC mold design temperature is usually between 140 and 160. When designing the mold temperature system, attention should be paid to keeping the temperature of the entire surface of the mold the same. Unification of temperature can reduce deformation, increase dimensional stability and unify product surface.

Q: What are the advantages of SMC?

A: SMC offers a remarkable weight advantage, being up to 30% lighter than equivalent steel panels. This substantial weight reduction directly contributes to improved fuel efficiency and reduced emissions, aligning with stringent environmental regulations and consumer demands for more eco-friendly vehicles.
