Top Class Plasma Nitriding Processing in Japan
CEMM has established a dominant place for its diversified heat treatment lineup in Nagoya, the center of heat treatment since 1956. This heat treatment lineup includes proprietary plasma nitriding treatment. After becoming the member of the DOWA group in 2006, CEMM plays a leading role of the DOWA heat processing business.
Address : 19-1, Ukishima-cho, Miizuho-ku, Nagoya-shi, Nagoya 467-0854
Employees : 98 (As of March 31, 2014)
Focusing on Plasma Nitriding Treatment
CEMM succeeded in developing the plasma nitriding treatment in 1974 and started to offer the treatment services to other companies using the special furnace dedicated to the treatment. As of now, DOWA THERMOTECH has the only one plasma treatment plant: CEMM treats 5 million units a year focusing on automatic transmission parts for automobiles It is the largest in Japan as a single treatment plant. CEMM deploys all-around nitriding treatment, responding to needs of the automotive industry in terms of cost and scope of treatment.
Besides the automotive industry, uses range from construction machines, industrial robots, ships and aviation. Proper systems are put in place to respond to the various needs of a wide range of industrial needs, including a variety of heat treatments for aluminum alloys as well as gas carbonizing treatment, in addition to plasma nitriding treatment.
The Renewal of the plant have improved Safety, Quality and Productivity
It has been already half a century since the establishment of CEMM. CEMM had difficulty in coping fully with the current needs from industry due to aging of its plant buildings that were constructed thirty or forty years ago. Also the layout of the plant buildings were not suitable for responding to its current expanding business. In 2011, CEMM started the three-year renewal project for major two plants (S2 plant for plasma nitriding and N2 for gas carbonization) to ensure a long lasting business base in the Chukyo metropolitan area centered on the city of Nagoya in Aichi Prefecture.
In S2 Plant, sixteen plasma nitriding furnaces used to spread over three different locations, but in the renewal project, they will be integrated into one place, to eliminate wasteful movement of operators and increase productivity through enhanced equipment management. We will stop lifting of products by cranes from the first floor to the second floor for higher safety. In N2 Plant, a layout review enabled us to eliminate wasteful in-plant transportation, separate in-process products from finished products as well as heat treatment equipment from workplace. This improved the workplace environment to a great extent and increased safety, quality and productivity.

We reconstructed the plasma nitriding treatment and the carbonizing plants and reconstructed the aging buildings in our three-year project. For smooth progressing of the reconstruction schedule, in our concerted efforts, we succeeded in constructing buildings, proposing process changes to our clients, checking quality and managing changes along with the request simultaneously.
We will take the momentum from this renewal project to further improve quality and respond to a wide range of industry needs.
Naruhiro Kono
I was mainly in charge of construction of S2 Plant in 2011 and of N2 Plant this time, for a total of three years. We had to construct a new plant while continuing operation of the plant. As a result we had to operate under a range of restrictions in terms of time and areas. The work did not progress as planned; however, we were able to complete the work successfully. I would like to thank all concerned.
I am sure all the members of CEMM who helped successful construction will be able to improve their plants even further. I would like to continue to make improvement together with all the members.
Won Gold and Silver Awards
at the QC Activity Presentation Conference in 2013
CEMM encourages employees to obtain qualifications such as heat treatment specialist certificates and the like. CEMM has three female heat treatment specialists (Class 1) and ranks No.1 in the DOWA THERMOTECH in terms of the number of employees with specialist certificates. Capitalizing on these qualifications and skills of employees, CEMM aggressively conducts improvement activities. As a result, CEMM team won the Gold and Silver awards last year at the QC activity presentation conference. CEMM also submitted the largest number of proposals for the past four years. We will promote these activities, aimed at achieving better goals.
