Pultrusion Process

Pultrusion is a manufacturing process for producing continuous length of reinforced plastic structural shapes with constant cross-sections.
Raw materials are a liquid resin mixture (containing resin, fillers and specialized additives) and flexible textile reinforcing fibers, the process involves pulling these raw materials (rather than pushing, as is the case in extrusion) through a heated steel forming die using a continuous pulling device.

The reinforcement materials are in continuous forms such as rolls of fiberglass met and doffs of fiberglass roving, as the reinforcements are saturated with the resin mixture (‘wet-out”) in the resin bath and pulled through the die, the gelatin, or hardening of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.

International Trends

Pultruded sections are well-established alternative to steel, wood and aluminum in developed counties and are fast catching up in other parts of the world, Structural sections have ready markets in oil exploration rigs, chemical industries etc.

Advantages of Pultrusion

Pultrusion is the most cost-effective method to overcome problems which conventional materials often can not fulfill and offering the architect, fabricator, athlete, and maintenance person a structural material for solving many design and engineering problems
