Prepreg manufacturing

Fabric impregnation with polymer resin in order to obtain semi-finished products (prepreg products), which serve as initial material for press-moulding or autoclave molding extrusion shaping.

Press-moulding

Moulding of products from prepreg in a closed two-sided mould set under high pressure and high temperature.

Injection moulding

Product moulding from thermoplastic (as a rule, granulated) material by its melting and subsequent injection into closed mould and its cooling up to curing.

Dry package impregnation in a closed mould by injection of polymer resin (RTM)

Manufacturing of composite products by pressure or vacuum delivery of the polymer resin into the cavity of a two-sided mould, prefilled with dry fibrefill.

Pultrusion

Continuous pulling of constant cross-section profile by feeding reinforcing glass-fiber materials impregnated with resin through a heated steel die.

Hand lay-up

Moulding of composite material, where reinforced component and resin are put on the mould, and a half-finished product is condensed by packing.

Assembling

Assembling of structures from glass-fiber profiles including their prior mechanical treatment (cutting, drilling, milling and turning), painting, forming sub-assemblies (spans etc.), preparation for transportation.

Vacuum infusion

Vacuum infusion It is the process when in the work space of the mould is made a discharging with the use of vacuum film (bag) and due to the pressure difference you can observe pulling-in of the resin and impregnation of reinforced materials. In comparison with hand lay-up, the method of vacuum infusion allows to get glass fiber with a higher reinforcement ratio and with lower content of pores. One more advantage of this method – is decrease of harmful agents (Example: Sterol) which are released within the production process
