In the filament winding process, continuous strands of resin-impregnated glass fiber are wound under tension onto a mandrel in precise geometric patterns to build up the part which is then cured to form the finished parts.

Multiple laminate layers, composed of resin, reinforcement glass and other materials are applied to a rotating mandrel, which is formed from a continuous steel band continuously traveling in a cork-screw motion. The composite part is heated and cured in place as the mandrel travels through the line and then cut into a specific length with a traveling cut-off saw.

The raw materials, including resin, chopped reinforcement (fiberglass), and filler, are fed into the interior of a rotating mould according to a specific proportion. Due to centrifugal force the materials are pressed against the wall of the mould under pressure, and the compound materials are compacted and deaired. After curing the composite part is removed from the mould.
