THE PULTRUSION

PULTRUSION is a continuous process for

producing composite constant section

profiles made with structural fibers suitably

oriented, bonded with a polymeric matrix.

By varying the fibers type or direction, or the

used matrix, noticeable variations can be

achieved in the chemical and or physical

properties of the product, so making it

suitable to the request.

The PULTRUSION process starts when the

reinforcing fibers pass through an impregnating

bath where they come in contact with the fluid

resin.

Following this, the impregnated fibers are

carefully guided through appropriate stations to

the die entrance, where the polymerisation

process is activated by high temperature.

It's important to underline that the

polymerisation process is fully completed

before the exit of the die, making the

process a 'closed-mould' process, so

reducing any volatile emission and assuring a

very elevated grade of curing. This permits

to obtain high chemical and physical

properties and a very limited ambient impact.

The relatively low cost of the dies (moulds )

necessary to realize a pultrused profile let to

size and realize the same profile in function of

the specific scope.

Is possible optimize the weight of the profile

and so reduce the costs, eventually

integrating more functions and let possible a

good cost/benefit ratio.

Can be pultruded also complex profile section

objects to maximize the benefits of a 'custom

tailored' project.

The profiles are done in continuous and in

every length compatible with transportation

( some profiles of small dimensions can be

rolled up).

PULLCOM has several lines of pultrusion and

some hundred dies.

For its lines dimensions, it can produce big

structural profiles, which drawing is in a

rectangle of about 100x30 cm.

It has several equipments for special

productions and post-production on request by

the customer
