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 increases, and energy-saving effects can be expected. When heat treatment is performed in a vacuum atmosphere, it facilitates the degreasing and degassing of organic substances adhered to the surface of metal materials, resulting in a surface that exhibits the inherent luster of the metal after processing. 【Features】 ■ It is possible to enhance the value of metal materials by maintaining their luster. ■ Work efficiency improves as post-processing such as acid cleaning and degreasing is no longer required. 【Examples of Products】 Common products made in a vacuum furnace ■ Bicycle gear ■ Fasteners ■ Bearings ■ Tools ■ Stainless steel gears ■ Orthodontic brackets ■ 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 Quenching 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 requirements regarding processing volume, work size, applications, and upstream and downstream processes, and proposes the optimal firing furnace or sintering furnace, including surrounding areas. 【Problem Solving】We have addressed the following issues: ■ It is wasteful 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 misalignment of the switch position occurs. The "firing 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 firing and sintering, as well as automatic transport from the degreasing process, can be designed.
