Advantages of Continue Filament Winding Machine

The resin system of both liner and structure is no-cleaning type which is the international initiative technique.
The steel tape heating and heat preservation system will make the production much easier in winter (used for pipes over DN1500mm when room temperature is rather low).
Mandrel is whole forged, thermal treated and drilled with stepped holes in the center adopting material of 42CrMo. The mandrel diameter is increased from 360mm to 400mm. The stepped type can avoid the mandrel breaking problem resulting from welding technique.
The membrane pumps in resin dosing system are of LEWA (GERMANY); the resin will not generate heat in the output process and not be cured after short suspend production.
We'll offer full CFW pipe design and layup process.

Components of Continue Filament Winding Machine

Mandrel

The mandrel serves as the base on which the fibers are wound. It can be removable, in cases where the final piece is hollow, or remain as part of the structure.

Fiber Feeding System

This system controls the continuous supply of fibers to the process, maintaining adequate tension and preventing breaks or improper overlap.

Impregnation System

The fibers pass through a resin bath before being wound on the mandrel. This system must ensure correct fiber impregnation without excess or lack of resin.

Winding Head

Controls the angle and pattern of fiber winding around the mandrel, which can be programmed for different geometries and types of parts.

CNC Control

Modern filament winding machines are equipped with CNC controls that allow precise programming of winding parameters, ensuring repeatability and accuracy.

FAQ

Q: What is a filament winding machine?

A: A continuous filament winding machine (CFW Machine / CW Machine) is a machine for laying filament windings continuously over a cylindrical steel band. The steel band is carried on a forward moving mandrel which is able to collapse and return to the beginning of the travel.

Q: What are the steps in the filament winding process?

A: Winding: The impregnated fibers are wound onto the rotating mandrel in a predetermined pattern. Consolidation: The wound fibers are compacted onto the mandrel surface. Curing: The wound structure is cured, often involving heat application. Mandrel removal: Once cured, the part is removed from the mandrel.

Q: What is the difference between filament winding and braiding?

A: Filament winding is commonly used for pipes, tubes, and cylinders but braiding can be used for more complex geometries for more structurally demanding applications, such as I-beams, automotive crash cans (energy absorbers), car chassis components, and aerospace box spars.

Q: What is the working principle of winding machine?

A: The working principle of winding machine is to take the yarn or silk from the tube yarn down, introduce the guide yarn and the silk plate through the guide yarn and the screw rod, then pass through the gap between the clearing yarn and the silk plate through the disc tensioner, then through the groove of the guide yarn ...

Q: How do you maintain a winding machine?

A: Establish a routine maintenance schedule.
Keep the machine clean and free of debris.
Lubricate moving parts regularly.
Monitor electrical components and connections.
Inspect and maintain belts and tensioning systems.
