1. Pultrusion technology
While in all cases pultrusion remains a continuous composite material transformation process capable of generating profiles of constant cross-section, there are several "technological filiations" within this large family.
The pultrusion of thermosetting resins and thermoplastics first of all, but also 2 or 3 derivative technologies: pullwinding, pullforming and pullpress.
1.1 Pultrusion of thermosetting resins
This is by far the most widespread family of composites today (over 99% of the market). Figure 1 shows the main stages in the transformation of the basic constituents of composites, which, in just a few meters, go from the...

Industrial organization
The vast majority of companies have 2 or 3 pultrusion lines, while the European market leaders have between 15 and 20.
Their organizations all operate in continuous production (3 x 8 shifts) to avoid laborious tool assembly operations, which can take from 3.4 hours for very simple, small profiles... to almost a week for complex, large-scale tooling......
