Sheet Molding Compound

Flex composites, as a company with 20 years of experience in producing and using composite materials, take pride in being a composite materials professor, using cutting-edge technology in materials and manufacturing processes to provide our customers with a competitive advantage in their industry.

Fiberglass & Resin

The Chopped Fiberglass are synchronously transferred on the layer of pre-formulated resin.

laminating process

The Chopped Fiberglass, Fiberglass Fabric Layer, Polymer Resin layers, and Plastic film layers are undergoing the process of laminating to shape a sheet.

Mechanical Stretching

The mechanical stretching process of sheet molding compound prevents dimensional change of resin when temperature changes.

Viscosity Testing

The test used a specific geometry and a motor to apply a force on the polymer resin sample.under certain conditions, correlations can be made between dilute-solution viscosity and molecular parameters such as molecular weight or polymer chain length

SMC Gathering

The yield out sheet molding compounds are gathered in a box and ready for pakaging

Packaging

The wooden packaged composite materials allow challenging transportation conditions.

Advantages of SMC & BMC



Weight reduction

Composites can be up to 70 percent lighter than steel, which help to easily replace a large number of metal parts.



Strength and stiffness

The resin provides ductility, durability and system cohesion. The fibers are largely contributing to strength and stiffness.



Electrical performance

Excellent electrical properties, particularly electrical strength, water absorption, and surface resistivity.



Fire retardance

Great fire retardance and low smoke generation is important for many applications and markets.



Precision Dimensions

The ability to compensate for shrinkage with special additives makes even the most challenging designs & engineering parts feasible.
