HEAT TREATMENT

METAL HEAT TREATMENT

  • Heat treatment

    Hardening is a treatment to increase hardness and strength of steel. Steel is heated until austenitized, then cooled rapidly (or quenched) in water, oil, or gas. Hardening makes steel drastically harder, but lowers toughness. Tempering equilibrates the steel for hardness and toughness that are ideal for intended use.

  • Heat treatment

    Normalizing and annealing process are intended to soften a steel, to improve machinability. In addition, it is able to reduce residual stress and improve the structure of the components that has been formed.

  • Heat treatment

    Vacuum heat treatment process is performed under vacuum atmospheres. It maintains high luminance with little surface deterioration of the treated material, and can be used for die and various metal components.

  • Heat treatment

    Austempering is an isothermal heat treatment, ideal for small components such as springs, clips and retainers. Compared with normal hardening and tempering, there are many positive characteristics such as significantly higher improvement of toughness and durability, and less contortion due to hardening. It is expected to greatly improve the quality of mechanical components for automobiles, office automation equipment, etc., which are continuously becoming lighter, thinner, shorter and smaller.

    The technical capabilities of metal heat treatment that realizes mass production while still providing "advanced and precise processing"

    Tohken Thermotech specializes in high-quality heat treatment processing that requires precision, such as for automobile engine parts.
    This is because it is a field in which we can best utilize the abundant know-how, technology, and human resources that we have accumulated over the years.
    We do not offer high prices just because we have advanced technology. We review materials and processing methods to realize applications and requests, and produce high-added-value products while achieving production at reasonable prices.
    In recent years, an increasing number of companies have come to appreciate our expertise and outsource advanced heat treatment processing to us. We are also happy to consult with you on whether in-house production or outsourcing is better, so please feel free to contact us.

    Our technical capabilities, which have been accumulated over more than 100 years since our founding, are unmatched in the metal heat treatment industry. It is no exaggeration to say that there is no heat treatment processing method currently in existence in the world that we cannot handle. We
    not only maintain high quality with already established technology, but we are also actively working on developing completely new material combinations and processing methods.
    We have participated in many manufacturers’ new product development projects and have realized the development of parts with new strength and functionality.
    Tohken Thermotech boasts world-class facilities, production capacity, and technical capabilities, as well as new technology development.

    Our company has received many awards from designated and certified companies. This is due to our
    efforts to mass-produce even difficult heat treatment processes by developing our own jigs and equipment, and to help manufacturers develop products with reduced costs and high added value. The fact
    that we maintain high quality even on mass production lines is perhaps the biggest point of praise.
    In addition to complex and advanced technical capabilities, we believe that the most important thing is the trust that allows customers to trust us with their products, and so we focus on our quality control system.

    Our greatest strength is technical consulting by a group of metal heat treatment specialists.
    Our proposals are wide-ranging and include material development, improvements to processing methods, line improvements and design, equipment design and installation, and outsourcing proposals, all tailored to your needs.
    We have a specialized equipment department separate from our manufacturing department, which allows us to propose optimal plans in one stop for all processes related to metal heat treatment, including not only processing methods, but also equipment selection and line design.
    We aim to coexist and prosper with our customers by providing higher added value from every angle, rather than simply providing processing on a contract basis.

    OUR BUSINESS

    General Heat Treatment

    Quenching and tempering
    This is a common treatment method in which steel is heated until it turns austenitic, then quenched in oil. We also have sub-zero equipment to suppress deterioration over time.

    Surface hardening heat treatment

    Carburizing/Carbonitriding
    This is a treatment method that involves permeating the material with carbon/nitrogen. We will make optimal proposals by utilizing our extensive lineup of equipment and accumulated experience.

    Special Heat Treatment

    Brazing
    This is a method in which the metal filler is melted and joined by capillary action. By processing in a vacuum furnace, stable quality can be maintained.
