Miyashita Spring Manufacturing Co., Ltd. Business Introduction

We will always pursue the accuracy and robustness that users demand at a microscopic level.

Miyashita Spring Manufacturing Co., Ltd. designs materials suitable for springs, such as piano wire, stainless steel wire, and phosphor bronze wire, and processes them according to user requests. Furthermore, our developed ultra-fine compression springs have made it possible to achieve the ultra-miniaturization of advanced IC circuit boards. We constantly pursue the accuracy and durability required by users at the micro level. In the field of ultra-precision springs, we have successfully achieved winding processing of extremely fine wire with a diameter of 0.016 mm and an outer diameter of 0.066 mm through our unique machine development and manufacturing processes. In the corporate member award system, we were recognized for developing the world's smallest spring, contributing to the miniaturization of electronic devices, and received an award from the Nihon Keizai Shimbun in March 1990.
