What is high-frequency hardening?

Introduction to quenching using high-frequency induction heating, a technology that has been around for a long time and was also used by swordsmiths.

First, "quenching" is a heat treatment technique that involves rapidly heating steel components and then cooling them quickly in water or other mediums, making the components hard and strong. The process of quenching using high-frequency induction heating is called "high-frequency quenching." While hardening steel components can make them brittle, applying quenching only to the surface while leaving flexibility in the interior (maintaining a state where the outside is hard and the inside is soft) can enhance strength. 【Features】 ■ Hardens and strengthens components by rapidly heating steel parts and then cooling them quickly in water or other mediums. ■ Improves strength by applying quenching only to the surface and retaining flexibility in the interior. *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros was seen."

The relationship between high-frequency hardening and other heat treatments.

The relationship between high-frequency hardening and other heat treatments.

Due to the short processing time, the cycle time is also reduced! It is a quenching method that consumes less energy and has excellent controllability.

We would like to introduce the relationship between our high-frequency quenching and other heat treatment methods. High-frequency quenching can be considered an efficient heat treatment method due to its short processing time, resulting in minimal distortion. Because the processing time is short, the cycle time can also be reduced. The equipment cost is comparable to that of nitriding treatment, but it achieves a deeper hardened layer. Additionally, because it consumes less energy, running costs can be saved. 【Features】 ■ Efficient with minimal distortion due to short processing time ■ Reduced cycle time ■ Equipment cost is comparable to nitriding treatment, but achieves a deeper hardened layer ■ Lower energy consumption leads to cost savings ■ Excellent controllability *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros" for reference. Operating hours: Monday to Friday, 9 AM to 5 PM.

[Case Study 4 on Heat Treatment Challenges] A must-see for those struggling with tolerances due to distortion!

[Case Study 4 on Heat Treatment Challenges] A must-see for those struggling with tolerances due to distortion!

Control over the total process is necessary for distortion! The factors causing dimensional changes are various.

In recent years, the precision required for parts has become more advanced, and it is not uncommon for tolerances in drawings to be specified at less than a micron. Incorporating dimensional tolerances is a challenge, but when heat treatment is applied, dimensional changes will inevitably occur to some extent. There are various factors involved, but broadly speaking, two main causes can be identified: "dimensional changes due to the release of residual stress" and "dimensional changes due to structural transformation." It would be simple if we could just set a grinding allowance and achieve the dimensions in the final process, but a larger grinding allowance increases the amount of work required, and there are some features, such as knurling or surfaces with subtle angles, that are difficult to correct. Control over distortion requires a total process approach, and our company is engaged in efforts and development to minimize distortion for various parts. In particular, when changing processes from atmospheric treatment to high-frequency quenching, significant effects can be expected. If you are facing issues with distortion, please feel free to consult us. *For more details, please refer to the PDF materials or feel free to contact us.*

Why heat treatment is necessary・1

Why heat treatment is necessary・1

In the current automotive industry, where miniaturization and weight reduction of components are required, hardening is an indispensable technology!

We will introduce why heat treatment is necessary and the benefits of quenching. First, one benefit is that quenching allows for the miniaturization and weight reduction of parts. Even small components can achieve strength equivalent to larger parts by increasing their strength through heat treatment, enabling miniaturization and weight reduction. The second benefit is the reduction of material costs. By applying quenching, it is possible to obtain strength equivalent to that of expensive materials even when using common materials. 【Features】 - Enables miniaturization and weight reduction of parts - Achieves strength equivalent to larger parts when strength is increased through heat treatment - An indispensable technology in the current automotive industry, where miniaturization and weight reduction are required - Reduces material costs - Achieves strength equivalent to expensive materials even when using common materials *For more details, please refer to the PDF document or feel free to contact us.

Why heat treatment is necessary - 2

Why heat treatment is necessary - 2

Improving cutting performance, fatigue strength, and wear resistance! Introducing the purpose of heat treatment.

We will introduce the reasons why heat treatment is necessary and the purpose of quenching. The first reason is improved sharpness. By applying quenching only to the cutting edge, the strength of the cutting edge increases. Next, there is an improvement in fatigue strength. In today's demand for lightweight components and longer product lifespans, this fatigue strength is being emphasized. Finally, there is an enhancement in wear resistance. By applying high-frequency quenching to harden the surface, we can prevent wear on components and improve wear resistance. 【Objectives】 ■ Improved sharpness ■ Improved fatigue strength ■ Enhanced wear resistance *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention that you saw this on "Ipros." Operating hours: Monday to Friday, from 9 AM to 5 PM.
