What is Sheet Molding Compound (SMC)?
Sheet Molding Compound (SMC) is a ready-to-mold composite material in sheet form. It consists of SMC resin (unsaturated polyester resin), fillers, thickening agents, low-profile additives, and glass fiber reinforcement. This combination results in a high-strength, lightweight thermoset material ideal for producing complex and durable components through compression molding.
Our Sheet Molding Compound Process: Precision and Consistency
At RealLand, we ensure excellence at every stage of the sheet molding compound process:
Raw Material Preparation
Precisely measured resins, fillers, initiators, and additives are mixed to form a homogeneous paste.
Impregnation
The paste is applied onto a film, and continuous glass fiber strands or chopped fibers are embedded into the mixture, ensuring full saturation and uniform distribution.
Maturation / Thickening
The material is stored under controlled temperature and humidity to chemically thicken, achieving optimal viscosity for handling and molding.
Molding
SMC sheets are cut, placed into a mold, and compressed under high temperature and pressure. This triggers cross-linking of the resin, forming rigid, high-performance parts with exceptional surface quality.
We maintain strict process controls and advanced monitoring systems to guarantee batch-to-batch consistency, dimensional accuracy, and superior mechanical properties in every product.
