Mitsui High-tec provides high quality and low cost motor core products with complete global service from die design, fabrication and stamping manufacturing.

High Quality and Low Cost

High Quality and Low Cost

Proven technology accumulated since our company foundation guarantees high quality and low cost for precision stamping dies and the MAC system which was developed in-house. MAC is a system that fuses motor core layers to complete each core product inside the stamping tool as they are stamped, eliminating the need for a separate process after stamping.
Mitsui's motor cores are used in a variety of applications from the high-precision 2.7 mm diameter micro motors of vibrators in portable phones, to the high efficiency and high output 300 mm diameter motor cores required by hybrid automobiles.
