Thank you for visiting the website of Edison Hard Co., Ltd.

Edison Hard Co., Ltd. began as a surface treatment division of Licht Seiko Co., Ltd. in 1979, and has grown for over 40 years thanks to the support of its many customers.
The molds that account for our main business are the cornerstones of Japanese manufacturing.
We cannot disclose the molds that we handle. This is because these molds are linked to the know-how and confidentiality of unreleased products and automotive, home appliance, and electronic parts companies.
We have been exploring heat treatment conditions together with our customers for various issues through the manufacture of these products, and have solved many problems and achieved results.
We will continue to refine our technology and work as one to help reduce costs, aim for even more precise surface treatments, listen sincerely to the opinions of our customers, and tackle even more advanced issues.
