Operating a highly unique business devoted to manufacturing chains using all methods

We operate the sole business in Japan capable of manufacturing chains by all methods: flash-butt welding, forging, and casting. Sumitomo Heavy Industries Himatex Co., Ltd. as it exists today builds on the lengthy histories and traditions of predecessors Nippon Chain & Machinery Co., Ltd. and Osaka Chain & Machinery Co., Ltd. We have built a record of demonstrating unique originality, leveraging the technologies and experience we have accumulated over the years to offer as our principal line of products anchor chains for naval vessels (solid-stud type), steel chains for navigation beacons (thickened long open-type), chains for general merchant ships (ordinary welded-type), and related accessories.
