AVK GUMMI

What AVK GUMMI does

AVK GUMMI A/S is a Danish private limited company founded in 1975 in Låsby, Denmark, that develops, manufactures, and sells high-performance custom rubber components for safety-critical industrial applications. The company serves five primary segments: drinking water, energy, food, healthcare, and technical products, supplying customers that include valve manufacturers (INOXPA, STÜBBE, Kieselmann), rescue equipment makers (Holmatro), concrete industry equipment producers (Haarup Maskinfabrik), pharmaceutical processors (DEFINOX), and urban water infrastructure projects (URBAN WATER RETENTION). It is largely an engineering-led custom compound and moulding business, not a commodity rubber supplier.

The technical platform centres on in-house custom rubber compound development (EPDM, FKM, HNBR, silicone, fluoro-silicone, polyisoprene, butyl, NBR, SBR/NR), proprietary rubber-to-metal, rubber-to-PTFE and rubber-to-fabric bonding, and moulding via injection, transfer and compression processes from micro-parts to items up to 2x2x0.8 metres. Manufacturing is anchored by one of the world's most advanced fully automatic mixing plants (4 mixing lines and 150+ moulding machines in Denmark) and an advanced pilot plant with cleanroom post-treatment for medico and healthcare production. Recent additions include a chlorine-resistant EPDM compound (ECW-70) and a PFAS-free transition programme for fluoroelastomers.

Commercially, AVK GUMMI runs a direct B2B field-sales motion with territory-based Key Account and Area Sales Managers covering Denmark/Sweden, the German-speaking region, the Benelux, France/Italy/Austria, and increasingly North America and Asia. Pricing is entirely quote-based, driven by annual consumption forecasts and tool investment. The company holds an unusually broad set of global certifications (WRAS, KTW-BWGL, ACS, AS/NZ 4020, NSF 61, FDA 21 CFR 177.2600, EC 1935/2004, BfR, 3-A Sanitary, EHEDG membership, EN 681-1, EN 682, EN 549, USP Class VI, ISO 10993, ISO 13485, ISO 9001, IATF 16949, ISO 14001, ISO 45001, ISO 50001) and produces from wholly-owned subsidiaries in Kunshan (China, since 2004), Waalwijk (Netherlands, since 2019) and Minden, Nevada (USA, since 2020), with a new US factory scheduled to open in 2026 and a majority stake acquired in Danish peer Gravlund Rubber Solutions in June 2026. Revenue, customers, and ownership are not publicly disclosed.
