Common Materials List for Molding

Compression molding can be categorized based on the type of material used: sheet molding compound (SMC), bulk molding compound (BMC), thick molding compound (TMC), and wet lay-up compression molding. The process utilizes heated metal molds mounted in large hydraulic presses and can be automated for improved efficiency.

Compression molding offers design flexibility, allowing for features such as inserts, ribs, bosses, and attachments. It also achieves good surface finishes, reducing the need for extensive post-processing and lowering finishing costs. Additionally, compression molding minimizes trimming and machining operations, further reducing labor expenses.
