SMC is sheet moulding compound.

 

SMC is a mixture of polymer resin, inert fillers, fiber reinforcement, catalysts, pigments, stabilizers, release agents, and thickeners. Manufacturing of SMC is a continuous in-line process. The base components of liquids and solids (paste) are bulk mixed and continuously metered onto to the surface of a carrier/barrier film, coating the film surface. Two mirror imaged metering stations operate simultaneously. One of the paste-coated carrier films are then layered with chopped fibers. The 2 carrier webs, paste & fiber are then brought together in the compaction section, where the sandwich-like layered components are kneaded into one homogenous compound sheet. The sheet is then fan folded into a container and stored in a controlled environment where maturation takes place, on its way to a specified viscosity.

 

In recent years, MDC devoted to research and develop processing SMC moulds of various products, such as auto front& rear bumper, front&rear door panels, electrical appliance, bathtub, container and dishware and so on.

 

The advantage of SMC molding parts is as follows:

• Good dimensional stability, including excellent thermal resistance.
• Pigmentable for molded-in color; best appearance with mold texture.
• Excellent property retention in cold and hot environments.
• Suitable for outdoor use in applications involving UV exposure and water.

 

Now SMC moulds has become our core business and our customers are Mercedes Benz, Audi, GM, etc.
