Sales Pitch

Business content
SPS joining technology
Spark Plasma Sintering (SPS) exhibits excellent characteristics even in the bonding field. We can bond not only materials of the same type but also materials of different types. For example, we can bond materials that are normally difficult to bond, such as stainless steel and aluminum alloy, copper and titanium alloy, and metal and ceramics. 
In SPS bonding (pulsed electric current bonding), a typical method is solid phase diffusion bonding, whereby solids are directly bonded together without the use of any powder, and there are various other methods such as sinter bonding using powder, thin body bonding using thin bodies, and inclined bonding using inclined composition structures.
Requests for testing/processing/production
We accept requests for testing (testing/trial manufacturing) and processing of electrical discharge plasma sintering (SPS, pulse energization pressure sintering) machines. We also offer consultations regarding production and research and development.
Equipment proposals
From the compact, desktop SPS machine for research and development use, through single-head large SPS machines, SPS production systems and dedicated machines for production use, we propose the optimal machine according to our customers’ usage and budget. We provide total support such as testing with our equipment before equipment installation, maintenance after equipment installation, and technical support.
Equipment maintenance technical service
We perform maintenance and technical servicing of SPS machines and peripheral equipment.
