We are a comprehensive manufacturer of metal heat treatment capable of meeting all heat treatment needs.
Marushin Heat Treatment Co., Ltd. is a comprehensive manufacturer of metal heat treatment that can meet all heat treatment needs, from mass production of products using large-scale heat treatment equipment for carburizing, quenching, and tempering batch processing, to individual heat treatment of molds using vacuum furnaces. We can provide heat treatment tailored to your requirements, from large items and mass production capable of 1,000 kg/batch for carburizing, quenching, and tempering, to precision parts using continuous furnaces. Additionally, to support researchers and developers who are conducting daily research, testing, and prototyping to create mass-produced products, we have established the "Prototyping Convenience Workshop" to offer suggestions and cooperation in heat treatment. If you are a development manager facing challenges such as having too small a quantity or too many conditions to receive heat treatment, please feel free to consult with us. 【Sales Items】 ○ Metal Heat Treatment → Vacuum Heat Treatment → Atmosphere Heat Treatment → High-Frequency Quenching and Tempering, Gas Nitriding → μ High-Frequency Quenching and Tempering ○ Prototyping Convenience Workshop → The concept is "We respond casually to anything, no matter how many."

Company information
Marushin Heat Treatment Co., Ltd. possesses one of the largest heat treatment facilities for batch processing of carburizing, quenching, and tempering. In our vacuum furnaces, we cater to all heat treatment needs, from mass-produced items to single pieces, including heat treatment of stainless steel and mold materials, as well as ferrous and non-ferrous metals. Steel materials are utilized in various ways in our daily lives. The mission of heat treatment is to create the performance and properties suited to each specific purpose of these steel materials, playing an important role in adding value to individual products. By bringing out the characteristics of steel materials through heat treatment, we aim to contribute to the advancement of manufacturing. In today's society of mass production and consumption, we have aspired to grow together with the local community since our establishment, placing great importance on "individual customers." This philosophy will remain unchanged as we continue to provide heat treatment that ensures customer satisfaction, while consistently focusing on "stable quality" and "shortest delivery times," striving to build a company that can accurately respond to requests.
