Introducing plastic processing, machining, and other processing technology from Yasojima.

Developed in cooperation with university research institutions, our roughness control technology digitally reproduces the conventional techniques of skilled craftsmen, allowing us to select optimal processing conditions to match the characteristics of individual plastic materials in order to achieve the desired surface finish.

Lapping: Flatness/parallelism: 5 μm Maximum diameter: 400 mm
Polishing: Surface accuracy: Ra = 0.01 μm Maximum diameter: 400 mm

Microhole machining, microfabrication, and roughness control are performed in our optimally designed and constructed Sendai Plant.

Anti-vibration floor construction
Designed and built under the academic guidance of the Tohoku University Graduate School of Engineering.
The latest in anti-vibration floor construction prevents vibration from outside and restricts the transmission of vibration.

Temperature and humidity control system
Designed and built under the academic guidance of the University of Shiga Prefecture Department of Mechanical Systems Engineering.
Our production facilities feature enhanced insulation and an air conditioning system that employs hot and cold water, and uses multiple sensors in each area to maintain a constant temperature of 21°C±1°C and humidity of 50%±10%.

Yasojima technology drastically reduces the occurrence of burrs.
We also have burr removal technology for removing burrs formed during processing.

• Flexible product sizes - Create shapes that are larger than the size of the material to be processed itself.
• Flexible design - Create shapes that are unachievable when only machining materials.
• Lower materials costs - Affordably process shapes that would ordinarily involve the creation of significant waste during the machining process.
