PNK: The heat treatment specialists creating that perfect finish

Article - February 25, 2023

A member of the Nihon Parkerizing Group, which consists of more than 30 companies, PNK has set in stone a policy to sell their products globally.


Established in 1956, Parker Netsushori Kogyo (PNK) forms part of the wider Nihon Parkerizing Group and is striving forward on a mission of growing global sales through increased new development of its heat-treating technologies. Company president Masataka Watanabe explains some of the elements behind the growth.

“Controlling CO2 emissions is stringent, with vacuum heat treatment now an international trend, so we are focusing on selling modern vacuum furnaces that contribute to the reduction of emissions. In addition to this, we continue to promote sales of the nitrogen control system (NITRONAVITM ) for our nitriding treatment process, which was created based on the needs of our customers. We have high expectations for this technology,” says Mr. Watanabe.

“We are also pursuing recycled technology for chemical waste reduction and we expect further synergistic effects with our heat treatment business. Meanwhile, with ambitions to become a more globalized company, we are developing a cloud-based remote monitoring system. In order to be successful, we continue to look for further tie-ups and alliances with foreign heat treatment companies.”

As the company looks to go global, Mr. Watanabe wants clients to know they can rely on PNK to provide what they need and respond effectively. “In the heat treatment field, people will be rushing to us for their needs to be solved,” he says, “If we can successfully achieve that, we can satisfy our customers as well as contribute to our society.”
