Spuitgietmatrijzen en schroeven voor de verwerking van met glasvezel versterkte kunststoffen
Injection moulds and screws for processing glass fiber reinforced plastics (GFRP) are exposed to exceptionally demanding operating conditions. Abrasive glass fibers, elevated processing temperatures, high injection pressures, and chemically aggressive additives can cause severe wear, erosion, and corrosion in critical tooling components. Material requirements therefore focus on outstanding wear resistance, high compressive strength, excellent toughness, corrosion resistance, and dimensional stability under continuous production conditions. Maintaining tight tolerances and consistent surface quality is essential to ensure part accuracy, process reliability, and long tool life.
BÖHLER high-performance steels are specifically engineered to meet the challenges of GFRP processing. Advanced tool steels, ESR and powder metallurgical grades provide an optimized balance of hardness, toughness, and wear resistance. Depending on component requirements, corrosion-resistant stainless tool steels and high-alloy wear-resistant materials are used for mould cavities, screws, barrels, and non-return valve components. Produced using advanced melting and remelting technologies, BÖHLER materials offer exceptional cleanliness, low inclusion content, and homogeneous microstructures, significantly improving resistance to abrasive fiber wear. Key quality features include strict chemical composition control, certified traceability, validated heat treatment processes, and consistent hardness profiles. Comprehensive quality assurance through wear testing, microstructural analysis, surface integrity verification, and non-destructive inspection ensures reliable performance. BÖHLER materials help mould makers and processors increase productivity, extend maintenance intervals, and reduce total operating costs in demanding glass fiber reinforced plastic applications.
