Koshin’s commitment to innovation and excellence is unwavering. Since its inception, Koshin has continually invested in cutting-edge product testing and development. In 2013, the company underwent a significant transformation, revamping its production facilities with advanced technologies such as in-house aluminum die casting and production automation. This overhaul, coupled with state-of-the-art process flow management, underscores Koshin’s dedication to delivering products of unparalleled quality. Unlike some competitors who inflate performance values, Koshin guarantees the accuracy of the performance specifications outlined in our catalog.
