Thermal's heat treatment

Thermal’s heat treatment equipment is widely used in the metal (steel and nonferrous metal) industry and other fields.
The heating source of the equipment uses an electrical resistance heating system that enables accurate control. Our strength lies in small-lot production in heat treatment of steel, as well as bright treatment and large-volume production in heat treatment of stainless steel and nonferrous metals.

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)
Heat treatment of steel
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)
Bright heat treatment
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 of nonferrous metals

Heat treatment of nonferrous metals is basically the same as that of steel. The heat treatment alters the properties (hardness, softness, ductility) of nonferrous metals without changing their shapes by a combination of heating and cooling.

Target works (typical examples)
Heat treatment of nonferrous metals
Material Copper alloys, aluminum alloys, titanium alloys, gold, silver
Products Connector parts, contacting materials, automobile wheels, eyeglass frames, fashion accessories, automobile parts, aircraft parts
