GFRP processing combines glass fibres with thermoset or thermoplastic resins using lay‑up, infusion, RTM (Resin Transfer Molding), or pultrusion (pull-through composit process). With steel or composite tooling, it produces lightweight, corrosion‑resistant parts for automotive, marine, wind energy, and industrial applications.
Glass fibre reinforced plastic (GFRP) processing involves combining thermoset or thermoplastic resin systems with glass fibres to produce lightweight, high‑strength composite components. Common processes include hand lay‑up, spray‑up, vacuum infusion, resin transfer molding (RTM), pultrusion, and compression molding. Glass fibres—typically E‑glass or S‑glass—are supplied as mats, woven fabrics, rovings, or preforms and are impregnated with polyester, vinyl ester, epoxy, or thermoplastic resins. Tooling requirements depend on the chosen process: open molds made from gel‑coated composite structures are used for manual lay‑up, while closed molds in aluminum or alloyed tool steel enable dimensional accuracy in RTM and compression molding. Heating systems, vacuum equipment, and release agents ensure proper curing and surface quality. GFRP parts offer high stiffness‑to‑weight ratios, corrosion resistance, and design flexibility, making them widely used in automotive exterior panels, wind‑turbine blades, electrical housings, infrastructure reinforcements, sports equipment, and marine structures.
BÖHLER K390 MICROCLEAN is a high-alloyed, high-performance cold work tool steel manufactured using powder metallurgy. This material has the highest alloy content in the group of cold work tool steels with high vanadium content. The high alloy content gives this material outstanding wear resistance. At the same time, the powder metallurgical manufacturing process creates a uniform matrix with finely distributed primary carbides. Among other things, this leads to good material toughness. BÖHLER K390 MICROCLEAN is a problem solver for applications requiring extremely high wear resistance and compressive strength.

Read MoreUddeholm Tyrax ESR combines best in class toughness, corrosion and wear resistance. This grade was developed for molding of high performance plastics often filled with glass fiber reinforcements and additives like flame retardants. This matrix- based microstructure is designed to achieve a high-gloss surface by only a few polishing steps, dramatically reducing the tool lead time and enabling production of top quality plastic parts. Uddeholm Tyrax ESR can achieve a high hardness (up to 58 HRC) and is a suitable upgrade from AISI 420 ESR, AISI S7 and AISI 440C. Benefits good dimensional stability at heat treatment and in service even microstructure and small grain size good hardenability Uddeholm Tyrax is also available for Additive Manufacturing, powder for processing Laser Powder Bed Fusion (LPBF) and Laser Metal Deposition (LMD).
