New Material Development Equipment
Metal Heat-Treatment EquipmentFeatures
Compatible with a Wide Range of Industries and Their Target Materials
Our thermal heat treatment systems provide heating technology for use in an array of fields, including metals（ steel and non-ferrous metals）.
Clean Energy Electricity That Is Easy to Introduce
Our products use electric resistance heating, which can be controlled precisely.
From Small Lots to Mass Production
We specialize in multi-model, small-lot, low-volume production heat treatment systems for steel, and in bright heat treatment and mass-production heat treatment systems for stainless steel.
Heat Treatment of Steel
Steel heat treatment is a process to alter the properties of metal shapes by hardening or softening them according to their applications, without changing their shapes.
Target Works (Typical Examples)
| Cold work tool steel | Caulking, deep drawing, forging, dies, stamping |
|---|---|
| Hot work tool steel | Die-casting, casting molds, forging, dies |
| High-speed tool steel | Drills, end mils, taps, reamers, injection molds for plastics |
| Tools and jigs | Probes, collet chucks, punches |
| Parts | Gears, springs, clutches, bearings, screws, chains |
| Products | Latch needles, fish hooks, pocket knives, kitchen knives, saws |
Bright Heat Treatment
Generally, heat treatment heats the target work to temperatures higher than the transformation point of the metal, which causes the work’s surface to combine with moisture and oxygen in the air, resulting in oxidation.
The bright heat treatment is a process to change this surface to a bright (glittery silver white) condition.
Target Works (Typical Examples)
| Heat treatment | Products |
|---|---|
| Annealing | Flexible pipes, pipes for automobile components, watch parts, bellows, pressed parts |
| Solution heat treatment | Stainless steel pipes, tableware, stainless steel watch bands, pressed parts |
| Quenching | Kitchen knives, scissors, disc brakes, tools, cutting tools, micro-shafts for small motors |
| Brazing | Heat exchangers, automobile parts, hydraulic equipment, gas appliances, building parts, farm equipment parts, stainless steel filters |
Heat Treatment for Non-Ferrous Metals
Heat treatment of non-ferrous metals is basically the same as that of steel. The heat treatment alters the properties (hardness, softness, ductility) of non-ferrous metals without changing their shapes by a combination of heating and cooling.
Target Works (Typical Examples)
| Material | Copper alloys, aluminum alloys, titanium alloys, gold, silver |
|---|---|
| Products | onnector parts, contacting materials, automobile wheels, eyeglass frames, fashion accessories, automobile parts, aircraft parts |
