A Series

This series consists of representative models of small-scale heat treatment furnaces used for non-oxidation quenching of small-lot parts. Models best suited for machinery structural steels (carbon steels, alloy steels) and tool steels (cold work die steels, hot work die steels, plastic mold steels) are available. Since heat treatment is performed in a non-oxidation atmosphere, oxidation and decarburization can be restricted.

R-L Series

Models in this series are widely used for tempering, annealing, age hardening, shrink fitting, baking, and various types of drying in a low temperature range.

R-H Series

This series uses a surface hardening method, which improves wear resistance by hardening the work surface while retaining softness within the work to allow energy loaded on the surface to be absorbed internally. This method is used in carburizing and quenching, carbonitriding and gas soft nitriding.

SH Series

This series includes heat treatment furnaces for non-ferrous metal materials including copper, aluminum, magnesium and titanium alloys. Hydrogen, nitrogen, argon and other gas atmospheres are used. The hot gas circulation method ensures excellent temperature distribution.

N Series

This series includes heat treatment furnaces for non-ferrous metal materials including copper, aluminum, magnesium and titanium alloys. Hydrogen, nitrogen, argon and other gas atmospheres are used. The hot gas circulation method ensures excellent temperature distribution.

C Series

Various types of continuous heat treatment furnaces for volume production of pressed and machined parts are available according to the material and shape of the target work Hundreds of Thermal's continuous furnaces have been installed at sites in Japan and overseas, and are used in a wide range of areas. Upon request, we can also test and prototype your product samples to propose the optimum conditions.
