Winding Technology

Winding technologies are suitable for producing items “precisely,” uniformly, “quickly,” ”efficiently,” and “in a large amount” and used for turning thin and long materials into small pieces in various industries.

In particular, the simple winding structures that reduce the number of winding parts (materials) have been employed in electronic parts such as Capacitors and Batteries.

What is required for winding structural electronic parts is a capability to precisely and continuously “process” “several” “sheet materials” “in layers. ” We have been pursuing to meet this requirement through the development of our technologies.

Since our foundation, we have been meeting requests of electronics parts manufacturers and laboratories in Japan and abroad, building experience and achievements for 50 years, by the use of which we now continue to develop research and mass production equipment to support our customers.
