The pultrusion process is an automated process for manufacturing fibre-reinforced plastic profiles, also known as pultrusion profiles or FRP profiles. In the continuous manufacturing process a profile is produced in a number of steps (see “The pultrusion process” graphic) through the targeted combination of fibre reinforcement and resin systems.
The pultrusion process offers a very high degree of creative freedom. The process allows profiles to be manufactured with individual properties such as mechanical, electrical, chemical or fire-retardant properties. This is governed by three factors that can each be optimised in the pultrusion process:
The careful selection of these factors enables profiles with individual properties and cross-sections to be produced for a range of applications. At Röchling, we use a variety of glass fibre, carbon fibre or basalt fibre reinforcements as well as UP, VE, EP and PUR resin systems for the manufacture of pultrusion profiles. We also manufacture our own moulds in-house, enabling us to produce profile cross-sections to your requirements. That gives us considerable latitude for creativity when it comes to pultrusion and means you get pultrusion profiles that are customised for your application.
