Application:
manufacturing of composite materials and constructional parts:
- granulated long fiber reinforced thermoplastics (LFT) for injection and compression moulding;
- unidirectional fiber reinforced strands and tapes, and on-line laying or winding;
- long-sized and curvilinear profiles of various cross-section, also with variable on length structure.
The process include:
- plastication by extrusion of thermoplastic polymers, including secondary, in the melt;
- impregnation by pultrusion of fibrous bundles (in particular, glass roving) with polymer melt, and also (depending on a product)
- making of granules - at manufacturing of LFT for injection or press moulding;
- making of tapes and on-line consolidation, laying or winding - at manufacturing of flat-bed parts or rotation bodies;
- consolidation of strands or tapes, on-line shaping or roll (dieless) forming - at manufacturing of profile products.
The most essential features:
- use a granules of a industry produced thermoplastic polymers and secondary polymeric raw with high melt viscosity (to 5000 Pa.s);
- use of roving with high thickness (to 5000 tex) and reduction of creels number and area, occupied by creels;
- possibility of change in a wide diapason of fiber fraction (from 10 up to 50 % of weight or more), of structure and properties of a composite material in the parts, and of a optimum fiber bundles arrangement in their sections;
- flexibility of process, quick and simple re-equipment (some minutes) on other product articles;
- high productivity (up to 3-5 kg/h x number of a 2400-5000 tex roving);
- lowered power and labor cost, decrease of a thermal destruction of a matrix polymer at the on-line operations with a molten polymer;
- use standard extruders and concerning simple impregnating, shaping and pulling devices.
Offered services:
- manufacturing of LFT with glass roving and various thermoplastic polymer matrix - polypropylene, polyamide, polyethylene terephthalate and other, including secondary;
- manufacturing of profile with glass roving and various thermoplastic polymers - polypropylene, polyamide, polyethylene terephthalate and other, including secondary;
- development of a products, equipment and devices;
- technical help in development of a products, equipment and devices, including transfer a know-how.
