Company information
Total products, that is our concept. In-house integrated production of metal design panels throughout all processes. Eliminating waste in logistics, contributing to delivery times, costs, and the environment.
This year marks the 57th anniversary since our predecessor, Daiwa Name Manufacturing Co., Ltd. (a limited partnership), was established. While primarily engaged in metal processing and anodizing surface treatment, our biggest feature is our integrated in-house production, which includes design and planning. We handle all processes in-house, including machining with milling, machining, and lathes, precision sheet metal processing with turret punches and benders, anodizing surface treatment, various types of powder coating, DTP plate production, silk screen printing, etching methods, and engraving with NC milling machines, all within our small factory of 15 employees. We also widely accommodate requests for standalone processes, such as anodizing treatment only.
