Only one Sendzimir mills specialized manufacturer in Japan
Contributing to society through the production of high-quality rolling materials
Aiming to be a niche top company
The Sendzimir mill was invented by Dr. Tadeusz Sendzimir and is an excellent rolling mill that was once said to be one of the 20 major inventions in the United States.
Sendzimir Japan, Ltd. (abbreviated as “SEJAL”) is a company in charge of the engineering, delivery and commissioning of Sendzimir mills and was established in 1962 as a joint venture between T. Sendzimir Inc., USA, Sojitz Corporation (formerly Iwai Sangyo Co., Ltd.) and Hitachi, Ltd.. Sendzimir mills are famous for their ability to realize efficient rolling result by the high rigid mill housing with small diameter work rolls. The functions of AS-U and lateral shifting of intermediate roll result in the achievement of accurate shape control.
SEJAL supplies a number of rolling mills to the field of cold rolling such as stainless steel, special steel, copper and copper alloys, silicon steel, etc. and the Sendzimir mills supplied by SEJAL have been in operation in a number of countries in the world.
Sendzimir mill is one of the few rolling mills that can roll hard and thin strips such as stainless steel, special steel, copper and copper alloys, silicon steel, etc. with high accuracy.
In recent years, in an era of digital transformation (DX), electric automobiles (EV)/ weight reduction, clean energy for decarbonization and energy efficiency improvement, demands for harder, thinner, and higher precision rolling materials are increasing.
Sendzimir mills contribute to the technologies and production of materials that support technological innovation in various industries such as EV, semiconductor lead frames, electronic devices, connector terminals for smartphones, and IT etc.
