The advantages of Pultrusion

1.The pultrusion process is a proven manufacturing method for obtaining high quality FRP profiles with consistently repeatable mechanical properties.

2.Some of the features of the pultrusion process are:

  • Complex shape and length capabilities

  • Precise positioning of reinforcements

  • Low scrap rates

  • Wide choice of reinforcements and resins

3.Pultrusion successfully combines a number of elements which can provide a wide variety and combination of properties and characteristics required by the final application of the product.

4.Pultrusion is a method of manufacturing either discrete or continuous lengths of fibre reinforced composites by pulling resin impregnated fibres through a series of forming guides.

5.They then pass through a heated die to cure the resin system, thus producing a rigid cured composite as it exits the die. The shape and dimensions of the end product are determined by the die cross section.

6.Pultrusion is an ideal process for the production of either solid or hollow constant cross section profiles.

Frp profile pultrusion machine Production Flow
 Pultrusion is an automated process for manufacturing reinforced materials into continuous, constant cross-sectional profiles. In virtually every case, a continuous reinforcing fibre is integral to the process and the finished product. The basic operation consists of pulling a reinforcement through a resin impregnation bath or other facility, and then through a die to produce the finished profile.
