Cologne, Germany -- Seal equipment and material specialist Sonderhoff group hopes to make 400 million seals per year by 2020, marketing director Peter Fischer told European Plastics News.
Sonderhoff, based in Cologne, Germany, develops and produces equipment and materials for application, encapsulation and gluing of single and two-component polyurethane and silicone seals.
Its main focus isformed-in-place-foam gaskets (FIPG) based on Fermapor PU and FermasilRTV silicone foam.
Automotive uses account for 25 percent of the FIPG applications, while electrical/electronics account for 35 percent and packaging for 20 percent. Fischer says Sonderhoff has more than 1000 material formulations, used to make more than 200 million seals each year.
FIPFG systems are used either as complete production cells, developed by moulding machinery producers, or as standalone downline systems. For example, Dräxlmaier uses the process to make engine-compartment components for luxury car maker BMW. Automotive applications include air ducts, fan-belt housings, brake lights, oil sumps and door modules.
Other applications include HEPA (high-efficiency particulate air) filter-housing seals, made using microbial-inert Fermapor K31 A-9020-17F and A-9308-5-VP5-F grades. And companies such as Mauser and Demmel use Fermapor K31 to make large-diameter food packaging covers.
