Tokyo South Plant
The South Plant is a 10-minute walk from the head office in Musashimurayama City. This plant features a state-of-the-art heat treatment furnace that enables heat treatment with low distortion and high sliding properties. It is also possible to carburize even hard-to-carburize parts.
With the mission of "supporting the foundation of the machinery industry," we will continue to meet various needs in the future.

Tokyo South Plant
The South Plant is a 10-minute walk from the head office in Musashimurayama City. This plant features a state-of-the-art heat treatment furnace that enables heat treatment with low distortion and high sliding properties. It is also possible to carburize even hard-to-carburize parts. With the mission of "supporting the foundation of the machinery industry," we will continue to meet various needs in the future.
State-of-the-art
heat treatment
The South Plant is a plant that is 20 years ahead of its time, utilizing state-of-the-art technology and capable of meeting the needs for higher precision. Like the main plant, it will handle small-lot production of a wide variety of products as well as mass production. In addition, machining and tool design and manufacturing are also planned.
We will propose the construction of a supply chain for integrated production of parts and process improvement.
Heat Treatment at Tama Metallurgy
Asphyxiation quenching
Less distortion reduction and polishing allowance
A process in which nitrogen is solidly dissolved in place of carbon before quenching, which allows quenching at a lower strain than carburizing or carbonitriding.
Characteristics of Nitrocarburizing and Quenching
I want to harden with less distortion, but
Nitriding is not applicable without alloy steel.
By quenching with nitrogen infiltration
hardening can be performed with the same degree of strain control as nitriding.
Oscillatory hardening
Increase hardness with less distortion
Aiming for low distortion by controlling the optimum quenching rate with varying oscillation conditions.
Characteristics of Oscillatory Hardening
Any air bubbles between the oil and the product
can be a source of distortion.
Vibration is applied to
Cooling while removing air bubbles.
Vacuum carburization
Carburizes even hard-to-carburize areas
A process that allows acetylene gas to adhere to the surface of a product and diffuse through osmosis the carbon in the acetylene gas on the surface of the product.
Features of Vacuum Carburization
Gas carburization.
Some areas could not be carburized.
Vacuum carburizing
Deep pore carburization is possible.
Sulfur dioxide nitriding
improve sliding properties
A treatment in which a sulfurized layer is formed over a nitrided layer. The formation of a lubricating nitrocarburizing layer improves wear resistance, seizure resistance, galling resistance, fatigue resistance, corrosion resistance, and other properties.
Characteristics of immersion nitriding
Conventional gas nitrocarburizing
Low sliding properties.
A sulfide layer is formed on top of the
nitride compound layer
on top of the nitride layerto
enhance solid lubricity.
Low temperature carburizing
and nitriding
Low distortion
Can be carburized/nitrided
Low temperature allows nitriding at a low temperature range that does not form chromium carbides and hardens without affecting the passive film and maintaining corrosion resistance.
Features of low-temperature carburizing and nitriding
I want to carburize/nitride but
I want to distort.
In low-temperature carburizing and nitriding
Carburizing and nitriding without distortion.
Features of Tokyo South Plant
Non-stop from machining
Machining and tool design and manufacturing will be implemented. We will propose the establishment of a supply chain for integrated production of parts and process improvement.
Suitable for mass production
The South Plant is equipped with facilities for mass production. We can meet various needs for automotive parts, aircraft parts, precision equipment, etc.
State-of-the-art technology for low distortion
We can heat treat to low distortion with state-of-the-art technologies such as nitrocarburizing quenching, carburizing-nitrocarburizing, vacuum carburizing, low-temperature carburizing, and low-temperature nitriding.Tokyo South Plant
