Company information
We have leveraged the technology we have cultivated through boiler manufacturing to aim to become Japan's leading "clutch door" manufacturer, focusing on the production and sales of round and square clutch door-type pressure vessels. As pressure vessels for production equipment, their applications have diversified alongside the development of various industries and advancements in production technology. We consistently manufacture everything from various steel plates to industrial machinery at our factory, and we also handle OEM for various processing equipment, including our own brand of mushroom culture sterilization devices and autoclaves. By newly establishing a research and development department, we aim to enhance our technological capabilities to respond to the high added value of production equipment, while further refining our "blacksmithing skills" to continue creating valuable products in the future.
