Company information
Shinsei Shoji was established in 1974 as the overseas sales division of wire butt welding machines for Hakusan Seisakusho Co., Ltd. In 1985, it entered into a dealership agreement with Clinton Company (spark testers) in the United States and began importing equipment for wire manufacturing. Utilizing the specialized knowledge and experience accumulated as a manufacturer’s sales division for butt welding machines, it subsequently increased the number of manufacturers it represents and now handles machinery for wire, cable, and electric wire manufacturing, measuring instruments, tools, and color masterbatches for fluoropolymer PEEK, among others. Currently, as a specialized trading company for equipment used in wire, electric wire, and tube manufacturing, it conducts business with approximately 200 wire, electric wire, and tube manufacturing companies both domestically and internationally. In recent years, it has started handling load cells and web guides from Swiss company FMS, receiving positive feedback from customers in the film, sheet, and printing sectors. Additionally, it has expanded its dealings with medical device manufacturers, focusing on measuring instruments for catheter tubes.
