SMC & DMC Moulding

SMC (Sheet Moulding Compound) and DMC (Dough Moulding Compound) are two prominent materials used in the process of composite moulding, each boasting unique properties and applications that cater to a variety of industrial needs. SMC is a pre-impregnated thermosetting material that is typically composed of a resin system, reinforcing fibers, and various additives, all of which are layered onto sheets for ease of handling and processing.

This material is particularly valued for its ability to be molded into complex shapes with excellent surface finishes, making it ideal for a range of applications such as automotive parts, electrical housings, and aesthetic components. On the other hand, DMC, characterized by its putty-like consistency, is formed by mixing resin with glass fibers and fillers in a malleable dough form. This allows for a high degree of customization and is well-suited for high-strength applications where durability is essential, such as in manufacturing industrial components, appliances, and even in the energy sector for producing items like wind turbine blades.

Both SMC and DMC undergo a thermosetting reaction during the moulding process, which culminates in a robust final product that exhibits excellent mechanical properties, dimensional stability, and resistance to various environmental factors.
