[Proposal / Solution Case] Product Distortion

[Proposal / Solution Case] Product Distortion

Case Study 2: "Improving mechanical properties leads to strain."

We would like to introduce a case study of metal heat treatment that our company proposed. The inquiry was about preventing significant "distortion" in parts with uneven wall thickness, which was causing residual scale during subsequent machining processes. The greater the temperature difference within the product during heating and cooling, the more significant the "distortion" that occurs after heat treatment. Our company ensures that the entire product is uniformly heated and cooled by aligning and setting the products for heat treatment, whether in continuous furnace processing or batch furnace processing. [Case Study] ■ Issue Significant "distortion" in parts, leading to residual scale during subsequent machining processes. ■ Solution Conducting heat treatment by aligning and setting the products to ensure uniform heating and cooling of the entire product. *For more details, please feel free to 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.*

Introduction to Heat Treatment: A Beginner's Guide from the Basics

Introduction to Heat Treatment: A Beginner's Guide from the Basics

[Functional and Property Improvement] Basic Knowledge of Heat Treatment Used in Automotive Parts and Aircraft Parts

Heat treatment refers to a metal processing technique aimed at improving the properties of metallic materials. The heat treatment process involves heating, holding, and cooling components or materials, which changes their characteristics. Why is heat treatment necessary? Metallic materials have the property of being brittle as they become harder. They are strong against deformation, but when a certain amount of force is applied, they can suddenly break or crack. It is common to apply heat treatment to improve the properties of metallic materials. We are currently offering a beginner's booklet that provides basic knowledge about heat treatment as a gift. *For more details, please refer to the PDF document or feel free to contact us.*

[Metal Heat Treatment Guide] What is Annealing?

[Metal Heat Treatment Guide] What is Annealing?

Introducing "tempering," which increases strength and ductility and is also used as a preliminary treatment for quenching.

"Annealing" is a heat treatment that removes internal stresses caused by processing, restores the structure to a standard state, and refines it. By performing annealing, strength and ductility are increased, making it useful as a preliminary treatment for quenching. Additionally, steel is held in the austenite structure for a sufficient period and then cooled adequately in air. 【What is Annealing】 ■ Removes internal stresses caused by processing ■ Restores the structure to a standard state or refines it ■ Steel is held in the austenite structure for a sufficient period and then adequately cooled in air *For more details, please refer to the PDF document or feel free to contact us.

Electric heating elements for industrial furnaces, used in metal heat treatment, electronic components, and chemical industry applications!

Manufacturing heaters suitable for electric furnaces with an internal temperature of up to 1200℃!

A metal heating element refers to a type of resistance heating element among general heating sources. 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.
