The international RAMPF Group based in Grafenberg, Germany, stands for engineering and chemical solutions and caters to the economic and ecological needs of industry. The family-owned company specializes in the development and manufacture of reactive resin systems, machine systems, and lightweight construction with composites.
RAMPF cultivates a global network of partners and has established production facilities in Germany, the United States, Canada, China, Japan, and Korea. This global presence ensures a high level of flexibility in production and short delivery times – crucial success factors for the group’s customers, who operate in the most dynamic international industries.
RAMPF places great emphasis on a proactive innovation culture. Every employee has the opportunity to develop new products and processes and bring these to fruition. This exceptional thirst for innovation, together with trusting relationships with customers, suppliers, and partners, are the cornerstone of the long-standing success story of RAMPF.
With its new speed-dependent dispensing technology, RAMPF is setting new standards in the processing of reactive resin systems. Slow and precise around corners, ultra-fast in a straight line – dispensing robots can now achieve “lap times” like never before, more than halving lead times in series production. The new technology is based on volumetric forced dispensing, the direct coupling of dispensing capacity and axial feed, which makes the dispensing system extremely flexible and responsive.
The performance and complexity of electrical/electronic components are rapidly increasing – and so is the importance of control cabinets. They serve as control centers in which electronic components of machines and systems are protected from moisture, dirt, heat, and cold. For this challenging task, RAMPF Polymer Solutions has developed high-performance sealing foams consisting of PU and SIL systems. The two component materials are UL50 and UL 508 listed and meet the IP ratings (IP 67 and IP68).
RAMPF's pending technology RAKU® Microwave Curing increases the reactivity of 1- and 2-component polymer systems based on polyurethane, epoxy, and silicone by up to fourfold. The material is thermally activated directly after the discharge nozzle via electromagnetic waves and then applied to the component. Radiation is transmitted by waveguide to the activation zone only for a fraction of a second.

RAMPF's pending technology RAKU® Microwave Curing increases the reactivity of 1- and 2-component polymer systems based on polyurethane, epoxy, and silicone by up to fourfold. The material is thermally activated directly after the discharge nozzle via electromagnetic waves and then applied to the component. Radiation is transmitted by waveguide to the activation zone only for a fraction of a second. Viscosity and reactivity are thus continuously adjustable and can be regulated quickly, flexibly, and directly in the production process. Shorter curing and processing times reduce Work In Process and thus improve production efficiency.
Manufacturers also benefit from time and cost savings as well as a reduction in process steps and negative environmental influences. Handling stability is achieved at a much earlier stage. The annealing cycle can be significantly reduced; ideally, a curing oven is no longer needed. Moreover, reduced operator maintenance improves productivity as well as operating costs, as contamination in the mixing head is decreased, which in turn reduces the frequency of mixer cleaning.
