Low Pressure Carburizing with Oil quench
Low Pressure Carburizing with Oil quench
- Low Pressure Carburizing (LPC) with Oil quench is very popular in Japan. This is the technology for Zero CO₂ emission instead of gas carburizing furnace without changing material from low alloy to high alloy. We have been provided this solution as a pioneer.
LPC Feature
- Zero CO₂ emission
- Without IGO
- Good uniform carburizing capability for narrow gap/aperture and deep blind hole
- Ability to carburizing stainless steel
- For low alloy material treated by atmospheric furnace, switching to LPC without changing material.
Test Center
Sample tests are available in Europe and in Japan.
- Carbide-Dispersion Carburizing test is also available in Japan.

Vacuum Hot Press for Diffusion Bonding
Diffusion Bonding Technology
- “Diffusion bonding,” which enables precision bonding, direct, and dissimilar material bonding, has been attracting attention. Diffusion bonding is a method of joining by bringing the components into close contact that cause as little plastic deformation as possible, thereby achieving a metallic bond between the bonded surfaces.

Vacuum Hot Press
- Diffusion bonding is performed using this vacuum hot press. The vacuum furnace has a heating chamber consisting of a heater and heat insulator inside a vacuum vessel made of steel, and a vacuum pump is used to create a vacuum inside the furnace vessel to raise the temperature to over 1000°C to perform heat treatment of steel materials such as quenching and tempering. The vacuum hot press is a vacuum furnace with a press mechanism, and has the structure.

Test Center in Japan
IHI has started a diffusion bonding test service. In order to respond to customer requests for the best bonding method. Based on its accumulated know-how, IMS provides services for each customer development stage, from trial testing to Research and Development (R&D), business studies, and mass production launch.
