We can prototype various types of steel starting from just one piece.
That "small important part" becomes the heart of the machine. We provide consistent support from material selection to finishing after heat treatment.
Key parts that control the "movement" of automatic machines and specialized equipment. Shinwa Koki specializes in medium to small-sized steel components that require such functionality. We accommodate the processing of steel materials (carbon steel, alloy steel, tool steel) tailored to applications such as movable parts that require wear resistance and connection parts that require strength. We also excel in handling precision parts that require jigs for irregular shapes or multiple processes.
