吉川ハイプレシジョン君津工場 Company Profile

Our factory has accumulated technology in precision press processing over many years. We will continue to challenge ourselves towards innovations in press processing technology.

Since its founding in 1920, Yoshikawa Industries has been advancing its management based on the principles of respect, trust, and love, with a belief in the spirit of "respect for humanity." Building on the foundational technologies developed in the steel-related fields, such as safety, production management, and quality control, we continue to challenge new technologies with a spirit of daily improvement and creativity. We have expanded our diversified management into areas such as engineering, electronics, system engineering, and new materials, steadily accumulating results. The Yoshikawa High Precision Kimitsu Plant specializes in precision press processing within our electronics division, one of our business areas. This plant began operations in 1988 with the precision press and mold business. Based on the knowledge and technology cultivated there, we now supply domestic and international companies as a manufacturer of pressed components for applications in electronic parts, electronic devices, home appliances, and automotive parts. In particular, we have achieved the world's No. 1 market share for LIDs used in quartz and SAW devices for mobile phones.
