Pullwinding Machinery

Pullwinding is a unique manufacturing process that is an advanced version of pultrusion. The primary distinction between the two is that pullwinding incorporates winders that wind fiber in the crosswise direction during the pultrusion process. This technique results in profiles with enhanced strength and stiffness, especially when compared to traditional pultruded profiles.

The pullwinding process consists of four main steps:

  1. Reinforcement Alignment and Resin Impregnation: This step ensures that the fibers are correctly aligned and thoroughly impregnated with resin.
  2. Shaping and Heating in a Die: The impregnated fibers are shaped and heated within a die to give them the desired form.
  3. The Pulling Process: The shaped and heated fibers are then pulled through the die.
  4. Final Product Formation: The pulled fibers solidify to form the final composite product.

Pullwinding technology allows for the production of strong, lightweight, and extremely thin-walled composite tubes and profiles. These products are designed to meet demanding mechanical requirements, making them suitable for various applications.

Key Points:

  • Pullwinding offers a unique approach to manufacturing composite profiles and tubes, setting it apart from traditional pultrusion methods.
  • The incorporation of winders during the pultrusion process enhances the strength and stiffness of the resulting profiles.
  • The versatility of pullwinding machinery makes it a valuable asset in the production of high-quality composite materials.
