Description
Few years back we also started working on the machines for FRP pipe industry and one of the successful one
is Filament Winding Machine. The machine is mainly used for manufacturing open (cylinders) or closed end
structures (pressure vessels or tanks). It involves winding filaments under tension over a rotating mandrel.
The mandrel rotates around the spindle (X-axis) while a delivery eye on a carriage (Y-axis) traverses
horizontally in line with the axis of the rotating mandrel, laying down fibers in the desired pattern or angle to
the rotational axis. The most common filaments are glass or carbon and are impregnated with resin by
passing through a bath as they are wound onto the mandrel. Once the mandrel is completely covered to the
desired thickness, the resin is cured. The mandrel is heated in an oven and once the resin has cured, the
mandrel is removed or extracted, leaving the hollow final product.
Our standard filament winding machines can be operated stand-alone but are also prepared for integration in
a semi-automatic or automated composite production line as customer’s requirement.
