Process confirmation

What is process verification?

Our "Sales/Web System" allows our customers to check our internal heat treatment schedule and the process progress of products entrusted to us in real time via the Internet.

The current progress status can be viewed by selecting the following items from the "Process Check" menu on our website.

We hope that this system will be of help to you when you plan your pre- and post-processing of our heat treatment process.
