Mitsui High-tec, Inc. – We have been producing the industrial machineries and tools since 1949

Mitsui High-tec, Inc. has been contributing to development of the electronics, automobile and industrial machinery. We produce, exports, and sells IC leadframes, motor cores, mold dies, trim and form dies, IC assemblies, precision tooling and parts, stamping dies, precision machine tools, and other type of stamping tools in Japan and internationally. The company was founded by Takaaki Mitsui in 1949 and is headquartered in Kitakyushu, Japan.

Products:

• Precision Tooling / Precision Parts
  Since its foundation, Mitsui High-tec, Inc. has produced a wide range of tooling (kanagata), specializing in those for motor cores and IC leadframes. Electric motor cores (rotors and stators), automobile components, coins, IC leadframes, resin injection molding and so on: Mitsui’s stamped products and precision tooling are used all over the world.
  Precision tooling for motor core is cost efficient as well as helps environment by conserving energy and natural resources. Our mission is to provide products useful to people all over the world.
  In fact you will find Mitsui motors in various products such as air conditioning systems compressor, hybrid vehicle drive motors. We also newly built a precision tooling factory as an effort for improving product quality under clean, controlled environment.

• Leadframe
  A leadframe is a thin layer of metal that connects the wiring from tiny electrical terminals on the semiconductor surface to the large-scale circuitry on electrical devices and circuit boards. Leadframes are used in almost all semiconductor packages.
  Mitsui High-tec accomplished the production of IC leadframes by precision-die-stamping for the first time in the world and, at present, we are producing leadframes not only by stamping but also by chemical etching.

• IC Assembly
  Mitsui High-tec Inc. is tackling the development and mass production of IC package and has prepared abundant product lineup backed up by our ultra-precision technology base having been polished since its foundation in order to respond to customers’ demand.
  We are internally producing IC leadframes that are the most important components among IC Assembly materials. In addition, by own development of dies, machine tools and jigs, based on our long-accumulated manufacturing technology, we can flexibly respond to the diversified needs arising form development to mass production and supply products in a short delivery term and at a low price.

• Motor Core
  A large motor is used in a hybrid car as a driver. The motors of this type are for driving a large device but they are manufactured in full consideration of efficiency and economy so as to be ecological and to ensure the performance of comfortable drive.
  Furthermore motors are used in many places where electricity works such as personal computers, household electrical appliances, electrical equipment and robots.
  We are producing many products deeply related to our daily life such as the parts constituting a motor and the dies for producing rotors and stators, and also offering stamping service as a comprehensive supplier of dies.
