2. Profile production processes
2.1 Pultrusion
It's a process resulting from the English verb "to pull", and the end of the term "extrusion", a process used in the thermoplastics industry.
Both pultrusion and extrusion are designed to produce profiles, and use in-line equipment whose main components are the dies and the drawing bench.
Extrusion is the pushing of a material through a die, while pultrusion is the pulling of a resin-preimpregnated fibrous support through a die using a powerful traction bench (500 to 1,000 daN).
TDA pultrusion began in the 1960s and now accounts for 4% of the total European TDA market.
The various studies begun in the 1980s on thermoplastic pultrusion (TP) by impregnating fibrous reinforcements...
