About Us


We aim to manufacture products that will surely satisfy our customers!
We introduced advanced technologies such as CNC machine tools and focus chucks early on, and further developed them into System 24 to improve work efficiency and reduce labor, enabling us to machine difficult-to-machine materials and high-precision parts. In 2002, we obtained ISO9001 certification, and in 2004, we were designated as a factory to be visited by the Asia Lean Production System Inspection Group. Currently, in addition to the conventional cutting process, we have started manufacturing and selling custom-made equipment and devices, making the most of our experience in unmanned and labor-saving processes. We are also expanding into new areas such as aluminum parts processing, glass epoxy processing, and overseas wastewater treatment business.
