We respond to various needs with the technology and know-how cultivated in the precision manufacturing area of the Suwa region!
"Quenching" is a process in which steel is heated to a temperature that transforms it into austenite and then rapidly cooled. While quenching increases hardness, it also makes the material brittle and prone to cracking, so tempering is always performed to adjust hardness and add toughness. "Tempering" refers to the process of reheating the material to a temperature lower than that used during quenching, holding it for a certain period, and then gradually cooling it. Our company is equipped with batch-type and continuous-type quenching furnaces, as well as various tempering furnaces, allowing us to meet a wide range of customer needs.

Company information
In our lives, there are many things that utilize steel materials. This is because steel materials can widely change their properties through composition and heat treatment, making them suitable for many applications. The mission of heat treatment is to create properties that match each intended use, playing a crucial role in ultimately determining the value of the product. At Marushin Manufacturing, which bears this important role, we aim to maximize the properties of metals and other materials through processing technology, which is the foundation of manufacturing. We continuously create processing, surface treatment technology, quality, and value, earning the trust of our customers and aiming to develop alongside the local community. We strive to cultivate human resources that can adapt to changing social environments, with each employee aiming to be an expert. We are committed to ongoing research and development of heat treatment technology and stability of quality, continuing our endless efforts and challenges to meet your needs.
