A series of technological innovations have made Mitsui High-tec a leader in the die industry. Manufacturers worldwide use our dies to stamp items: rotors and stators for electric motors, components for automobiles, appliances, and communications gear, leadframes for ICs, and transfer molds. Mitsui High-tec engineers got the company off to a solid start in 1949 by perfecting a new technique for grinding dies after heat treatment. This advanced die precision to within microns and established Mitsui High-tec's reputation for technological excellence. In the late 1950s, we were internationally recognized for our improvement of U.S. technology for producing tungsten carbide dies. These were harder than conventional steel dies, less affected by heat, and durable enough to do an one million continuous stampings for each of up to 100 sharpenings which was unprecedented at the time. In the 80's we greatly enhanced our ability to serve customers when we upgraded the software in our computer-aided design (CAD) system for precision dies. Tied into an automated production system, this improvement helps us get needed dies quickly to customers. Mitsui High-tec has been a pioneer in the industry for more than 50years. Today we still strive for excellence and stay as a precursor in the 21st century.
