The main advantage of SMC / BMC process is that it can produce the very complex shapes and large size profile by easy way and lower cost.
Different from pultruded profiles, when designing the SMC molded products, not only take the quality requirement and work under maximum load into account, but also make sure the structure meets the requirements according to the analysis of process and factors in the actual production.
Compression molding is the most common choice for high-volume composite parts and is often associated with SMC (sheet molding composite) and BMC (bulk molding composite) materials.
We supply various fiberglass products made from SMC and BMC materials: enclosures, insulators, boxes, nuts/bolts, seats/chairs, various parts for machinery and electrical, etc.
The technology processing
This process produces high strength, complex parts in a wide variety of sizes. Matched metal dies are mounted in a hydraulic molding press. The material charge is manually or robotically placed in the mold, heated mold halves are closed, and up to 2,000psi of pressure is applied. Cycle time ranges from 1-5 minutes depending on part size and thickness. Features such as ribs, bosses and inserts can be molded in.
Compression molded parts are characterized by net size and shape, two excellent finished surfaces and outstanding part-to-part repeatability. Trimming and finishing costs are minimal.
