The mould-making system from Büfa Composite Systems is being extended with the new VE 6699 Tooling Infusion resin. The material enables emission-free production in a closed infusion process and offers improved mechanical and thermal resistance for demanding GRP applications.

The system consists of the conductive Büfa-Tooling Conductive Gelcoat, the 1.-Layer Resin Büfa-Resin VE 0910 and the low-profile tooling resin Büfa-Resin VE 7100.

Büfa Composite Systems presents an expansion of its mould-making system: the newly developed mould-making resin Büfa-Resin VE 6699 Tooling Infusion now completes the already highly established system and specifically addresses the growing requirements of the GRP industry. Mould making is essential for GRP components, as almost every part is created in a negative mould. As a result, high quality standards and process reliability are required.

Back in 2018, Büfa was awarded a prize by AVK — the German Industrial Association for Reinforced Plastics — for the first electrically conductive moulding system. The reason for this was the use of nano-carbon materials, which create electrostatically conductive mould surfaces — resulting in increased safety (TÜV-tested) and durability of the moulds. The system consists of the conductive Büfa-Tooling Conductive Gelcoat, the 1.-Layer Resin Büfa-Resin VE 0910 and the low-profile tooling resin Büfa-Resin VE 7100. Since then, Büfa’s mould construction system has proven itself successfully in various applications in industries such as automotive, wind energy and marine.

With the new innovative Büfa-Resin VE 6699 Tooling Infusion resin, it is now possible to manufacture the mould in a virtually closed, emission-free system. This enables Büfa to fulfil its guiding principle of ‘protecting people and the environment’ and provides further advantages in terms of the process: increased mechanical and thermal resilience and expanded application possibilities in demanding applications. For this reason, the resin is part of the future-oriented Büfa-future range.

“Büfa-Resin VE 6699 Tooling Infusion is a logical innovation step for modern mould making. It combines high-performance material properties with the advantages of the closed infusion process — while reducing emissions and material usage,” explains Peter Kornas, Innovation and Sustainability Manager at Büfa Composite Systems. “Of course, the hand laminating process remains an important technology — depending on the project and requirements. Our customers benefit from the fact that Büfa offers the right solution for both classic and automated processes.” Together with Büfa Tec’s specialised machine technology for processing the products, Büfa offers customers a comprehensive system tailored to their individual applications.
