[Company strength]
We can manufacture sputtering targets in an integrated manner throughout all the processes from machining to bonding.  We have a relationship with aerospace businesses whose requirements are difficult to achieve.  We have a good record of processing different materials ranging from aluminum to difficult-to-cut materials (such as magnesium and Ti). We can handle orders for different processes including turning and milling, of various kinds  and in small lot  or for samples.  Our department of electrical design can handle manufacturing of automatic instruments by combining machining  and can-manufacturing process es and electrical installation.

[Business description]
Manufacturing of sputtering targets, precision machining , design and manufacturing of electrical instrumentation panels,  general iron work, and maintenance

[Industry]
Manufacturer of metal products and electrical machinery and apparatus

[Strength of products/technologies]
With our thin wall cutting technologies, we can handle slicing magnesium alloy and aluminum alloy from blocks in 1 mm thickness (the materials regarded as difficult-to-cut).  This cutting technique is used mainly for aerospace parts, which require precision and lightness.  
As for sputtering targets, we are the only company in Kansai with an integrated production system.  We can handle cutting, machining, bonding, and vacuum packaging, once clients provide us with target materials.  
As for welding  of metal materials, we have many technologies.  In aluminum welding, in particular, we can handle TIG and MIG welding and electronic beam welding to targets, depending on customer needs.  We have also established a bonding technology for different materials by utilizing the bonding technology between aluminum targets and back plates.

[Representative's message]
As for cutting processing of aluminum, we have high precision techniques accumulated in manufacturing of semiconductor and aerospace related parts.  We are now trying to obtain JISQ9100 certification in order to enter the airplane industry.  
As for sputtering targets, we have an integrated production system, which covers everything from cutting, bonding, and packaging/shipping.  We are highly regarded by our clients for our performance in quality and delivery.
In recent years, we have been making joint efforts across machinery and electric departments as well as with major companies and universities, in research and development of machines and equipment, as well as improvement of our in-house facilities.
Going forward, we will further hone our technologies and improve our safety and quality, and aim to expand overseas in the future.
