Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. The sheet is provided in rolls form or zig-zeg folding.

Process
Paste reservoir dispenses a measured amount of specified resin paste onto a plastic carrier film, This carrier film passes underneath a chopper which cuts the fibers onto the surface, Once these have drifted through the depth of resin paste, another sheet is added on top which sandwiches the glass. The sheets are compacted and then enter onto a take-up roll, which is used to store the product whilst it matures. The carrier film is then later removed and the material is cut into charges. Depending on what shape is required determines the shape of the charge and steel die which it is then added to. Heat and pressure act on the charge and once fully cured, this isthen removed from the mould as the finished product.

Advantages
Compared to similar methods, SMC benefits from a very high volume production ability, excellent part producibility, it is cost effective as low labor requirements per production level is very good and industry scrap is reduced substantially. Weight reduction, due to lower dimensional requirements and because of the ability to consolidate many parts into one, is also advantageous. The level of flexibility also exceeds many counterpart processes.
