Welcome to SARNES ingenieure OHG, Ostfildern Germany - Manufacturer of industrial furnaces, ovens or kilns under controlled atmosphere since 1980.We are specialized in continuous furnaces for sintering, hardening, steam treating, debindering and annealing. Thermal solutions for powder metallurgy, ceramic and magnetic structured parts. Thermal treating of solar active films and layers, InertCoating modules for OLED and special applications under protective atmosphere.Find all about our electrical or gas-heated belt furnaces for sintering, hardening, steam-treating and annealing with temperatures up to 1350°C under various protective atmospheres (100% H2, H2/N2 mixtures, endothermic and exothermic-gases).
sintering
Our furnace size ranges from 100mm belt width labratory type up to 1000mm and 2 x 600mm twin-belt furnaces with a capacity of more than 22 tons output per day.
Controlled atmosphere with in-built endo-thermic generator, improved delube zone LED3 (US patent), quench cooling zone are availble for sintering powder metal parts. A complete sintering and anneling line for sintering aluminium parts (T6) as well as sintering solution for special applications (hollow spere structures) and sintering of carbon parts can be offered.
steam treatingHigh quality steam treating of PM parts without boiler? This is Contiblu®! Contiblu® is our continuous steam treating furnace with in-built steanm generator and post burning chamber. The Contiblu® belt-furnace saves energy costs of more than$60,000 per year*. Find out what makes this process unique and why PM parts of Audi, BMW, Danfoss, INA, Mercedes, Opel, Volkswagen and many more are Contiblu®- steam treated.hardening and annealing
Continuous hardening furnaces, gas- or electrically heated with oil quenching bath, belt furnaces for annealing magnetic parts under pure hydrogen with flamefree outlet, all with extensive security features, online atmosphere control, touch-panel and optional database implementation. A new heat treatment line for aluminium sintered parts (T6 process) under controlled atmosphere was recently installed.
special applicationsfurnaces for sinter- hardening, carbon and aluminum sintering, sintering and debinding of hollow sphere and ceramic structures, annealing of magnetic parts under 100% H2 atmosphere even drying and debindering (MIM metal injection moulding), post-burning chambers (TNV), protective-gas generators and gas burners in various sizes are "taylor-made" solutions by SARNES ingenieure OHG in Ostfildern near Stuttgart, Germany.Our development company sit sintertechnik GmbH, offers thermal experimental services, furnaces and production development for special applications.

Before designing a production line of debindering and sintering furnaces, we usually test new feedstocks and alloys, like we did here at 1270°C under protective atmosphere. |
