Manufacturing Process

Pultrusion Process

Pultrusion is a continuous moulding process fabricating products of uniform cross section such as I Beams, Channels, Flat Bars, Rods, Hollow Section, etc, utilising glass fibre, resin, filler, peroxide and a release agent.

The glass reinforcement is drawn into a resin impregnation zone where the glass substrate is thoroughly impregnated with the resin mixture. The wet fibrous material will be pulled through a preformer into a heated die.

The shape of the end product is determined by the configuration of the die and the resin is then polymerised. This continuous and uniform method ensures consistency throughout the entire product length, therefore eliminating the possibility of weak spots.

Roving Mat

Unidirectional glass roving fibres give longtudinal reinforcement of the profile while mats give transverse strength.

Resin

Bonds with the reinforcement and provide resistance to chemicals.

Heated Die

Where polymerisation or curing takes place and product forms into the shape of the profile.

Pullers

Assures continuous drawing of the profile.

Automatic Cutter

Cuts product to the pre-set length.

Flatness & Thickness Consistency
Pultusion is pultruded from heated die, therefore flatness is consistence even cut into smaller sizes. Thickness is even and consistent.
Production of FRP hand-lay products is based on the workmanship and has a high probability of uneven surfaces due to the production process.

Impact Resistance
Continuous strand glass mat in FRP Products distributes the impact load to prevent surface damage even under sub-zero temperature and will not permanently deform and stay flat for the life of the product under closed mold pultrusion processing. High in mechanical strength.
Chopped strand mat used in FRP hand-lay products will probably deform or crack under impact without going under the closed mold processing and pultrusion system. Low in mechanical strength.
Will permanently deform under impact and take a permanent set (dishing in trench application due to overloading).High in mechanical strength.
