Fiberglass Products For Pipe Forming

We would love to hear from you.

Filament Winding Process

Traditional Filament Winding

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

Continuous Filament Winding

Multiple laminate layers, composed of resin, reinforcement glass and othermaterials are applied to a rotating mandrel, which is formed from a continuoussteel 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.

Centrifugal Casting Process

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.

Assembled Roving for Centrifugal Casting

Assembled Roving for Centrifugal Casting is coated with a silane-based sizing, compatible with UP resin and delivers excellent choppability and dispersion, low static, fast wet-out and good mechanical properties of composite products.
