Since post-processing steps such as acid cleaning and degreasing are unnecessary, work efficiency improves, and energy-saving effects can be expected. 【Features】 ■ It is possible to enhance the value of metal materials by maintaining luster. ■ Work efficiency increases as post-processing steps such as acid cleaning and degreasing are no longer required. 【Problem-Solving Examples】 We have addressed the following challenges: ■ Necessary hardness cannot be achieved due to heat escape during oil quenching. ■ We want to automate the process of pre-cleaning → carburizing → oil quenching → oil cleaning → tempering. ■ We want to digitize the results of heat treatment and the history of the process. 【Implementation Examples】 ■ We want to anneal copper without oxidation → "Vacuum Annealing Furnace." ■ We want to achieve a clean finish on the surface of processed items → "Vacuum Quenching Furnace." ■ We want to improve the wettability of brazing → "Vacuum Brazing Furnace." ■ We want to improve the hot working environment around the furnace → "Vacuum Furnace." *For more details, please contact us or download the PDF.

A "vacuum furnace" maintains luster and enhances the value of metal materials. Since post-processing such as acid cleaning and degreasing is unnecessary, work efficiency improves, and energy-saving effects can be expected. When heat treatment is performed in a vacuum atmosphere, it has the effect of degreasing and de-gassing organic substances adhering to the surface of metal materials, resulting in a surface with the original luster of the metal material after processing. 【Features】 ■ It is possible to enhance the value of metal materials by maintaining luster. ■ Work efficiency improves as post-processing such as acid cleaning and degreasing is no longer necessary. 【Examples of Products】 Common products made in a vacuum furnace ■ Bicycle gear ■ Fasteners ■ Bearings ■ Tools ■ Stainless steel gears ■ Dental braces ■ Chain components ■ Hinges for laptops 【Case Studies】 ■ Want to anneal copper without oxidation → "Vacuum Annealing Furnace" ■ Want to achieve a clean finish on processed items → "Vacuum Hardening Furnace" ■ Want to improve wettability for brazing → "Vacuum Brazing Furnace" ■ Want to improve the hot working environment around the furnace → "Vacuum Furnace" *For more details, please contact us or download the PDF.

The atmosphere gas used in the furnace can be reused as preheating in the space before heating without being discarded. As a result, the energy consumption is lower and more energy-efficient compared to heating from room temperature. Customization is also possible for degreasing and adjusting the purity of the atmosphere gas. San Furnace listens to your requests regarding processing volume, work size, applications, and upstream and downstream processes, and proposes the optimal sintering furnace or sintering furnace, including surrounding areas. 【Problem Solving】 We have solved the following issues: ■ It's a waste to discard hydrogen exhaust gas. ■ Manual changes to processing temperatures are being made in the pusher furnace. ■ Speed switching was done with limit switches, but there are issues with switch misalignment. The 'sintering and sintering furnace' can mass-produce high-precision parts and is used in the manufacturing of various mechanical components, including automotive parts. Continuous processing from degreasing to sintering is possible, and automatic transport from the degreasing process can also be designed.
