Technical Introduction: "Heat Treatment of Large Products"

Technical Introduction: "Heat Treatment of Large Products"

We have multiple facilities capable of handling large components, and we possess a top-class equipment system in the country.

Large components are designed to withstand greater forces compared to small components. Therefore, the required carburizing depth in heat treatment is also deeper. Additionally, as the components themselves become larger, the time taken for heating, cooling, and tempering, aside from processing time, increases. Our company enables a reduction in carburizing time by performing high-temperature, high-concentration carburizing. We have extensive experience in carburizing large components and possess technical know-how. We have multiple facilities capable of processing large components, and we have a top-class equipment system in Japan. In terms of processing capacity, we can handle outer diameters of up to 2200 mm and lengths of up to 6000 mm.

Electric heating elements for industrial furnaces that include this metal heating element are used in various industries such as metal heat treatment, electronic components, ceramics, and chemical industries. Our company manufactures electric furnace heaters suitable for furnace temperatures up to 1200°C using iron-chromium-aluminum alloy (FeCrAl), which is a type of metal heating element. The shapes of metal heating elements vary. Here, we introduce some of the products we handle. 1. Round wire coil heating element This is a heating element made by spirally winding round wire. The wire diameter and outer coil diameter are set according to the heater's capacity and temperature. 2. Strip heating element A zigzag-shaped circuit is formed by alternately slitting plate-like material. By adjusting the slit width, the resistance value of the heating element is changed, allowing for precise design of heater output. Additionally, we perform concave processing calculated to suppress deformation due to thermal expansion of the heating element. This technology has been developed uniquely by our company.

Technical Introduction: "Heat Treatment of Aluminum Alloys"

Technical Introduction: "Heat Treatment of Aluminum Alloys"

From large products to small items, we accommodate a variety of products!

Aluminum alloys are strengthened by heat treatment processes. Below are some representative treatments. 1. Solution Treatment and Natural Aging (T-4) This heat treatment involves rapidly cooling (water cooling) the aluminum alloy while maintaining a state where magnesium (Mg), copper (Cu), silicon (Si), and other elements are dissolved in the aluminum base (supersaturated solid solution). 2. Solution Treatment and Artificial Aging (T-6) This treatment improves hardness and mechanical strength by precipitating compounds of magnesium (Mg), copper (Cu), silicon (Si), etc., that were dissolved during the solution treatment, and is accelerated by raising the temperature to a certain level. 3. Stabilization Treatment (T-5) For some aluminum parts, to prevent changes in properties due to temperature rise during use, this process stabilizes the characteristics of the parts at a temperature slightly higher than the operating temperature. 4. Annealing Treatment (O Treatment) Annealing may be performed at around 350°C to improve workability. This is done when reprocessing parts that have already undergone T-6 treatment, particularly to reduce deformation in parts that are likely to deform. ● For more details, please contact us.

LODIC (Logic) processing

LODIC (Logic) processing

Lower distortion than carburizing nitriding, higher strength than soft nitriding! Ultra-low temperature carburizing nitriding hardening treatment.

LODIQ (Low Distortion Quenching) is our unique surface heat treatment method that fills the gap between "soft nitriding" and "carburizing hardening (carburizing nitriding)." It addresses issues such as "normal soft nitriding does not provide sufficient strength" and "normal carburizing (carburizing nitriding) results in excessive thermal distortion." Additionally, while maintaining the low distortion characteristics of LODIQ, we have achieved an increase in the strength of alloy steel with "LODIQ-AS," and we also offer "LODIQ-N," which allows for arbitrary changes in the compound layer composition to enable strengthening according to specific objectives. **Characteristics of LODIQ-AS** - Significantly reduces heating distortion and hardening distortion through ultra-low temperature treatment. - Increases resistance to temper softening of the re-surface, improving anti-seizing and anti-pitting properties. - Enhances effective hardened layer depth, internal hardness, and fatigue strength for low carbon steel LODIQ. - Enables the omission of finishing processes due to the suppression of abnormal grain boundary oxidation layers and the low distortion effect. *For more details, please download the PDF or feel free to contact us.*

What is heat treatment?

What is heat treatment?

Technology that gives life to steel components! Extracting various characteristics according to purpose.

"Heat treatment" breathes life into processed steel components, providing them with the hardness and strength necessary to withstand practical use as machine parts. By performing various heat treatments such as quenching and tempering, annealing, and normalizing, we can achieve a range of characteristics tailored to specific purposes, whether softening, hardening, or toughening the material. In other words, heat treatment involves improving the properties of metals by accurately controlling the application and removal of heat, as well as the temperature and time. 【Sales Items (Partial)】 ■ Gas carburizing ■ Carburizing and nitriding ■ LODIQ ■ LODIQ-AS ■ LODIQ-N *For more details, please download the PDF or feel free to contact us.

Vacuum heat treatment

Vacuum heat treatment

It is suitable for heat treatment of materials such as Ti, Inconel, and SUS thin plates, where oxidation prevention is difficult!

We would like to introduce our "Vacuum Heat Treatment." We adopt a method where all processes from heating to cooling are conducted in a heating chamber, preventing oxidation during cooling. Since vacuum is inert to metals, it is used as an ideal atmosphere, resulting in a good surface condition with excellent luster that requires little to no finishing. Additionally, the vacuum heat treatment heating is conducted solely by radiant heat, resulting in a very gentle temperature rise. This leads to a small temperature difference between the surface and the center of the treated item, allowing for uniform expansion and contraction, and enabling heat treatment with minimal distortion. 【Features】 - A vacuum pressure corresponding to 1×10−1 Pa retains 1 ppm of impurity gas. - Conducted solely by radiant heat. - The surface maintains its luster, and deformation is minimal, allowing for significant reduction in post-treatment processing. - No quenching oil is used, and there is no intrusion of oil into the chamber or vacuum furnace. *For more details, please refer to the PDF document or feel free to contact us.
