Feature 1<Microfabrication technology for medical equipment>
・We have delivered processed parts for medical equipment
for more than 20 years.
"If it's a palm-sized one, we will process any material"
・We are good at microfabrication of various materials
regardless of metal and nonferrous metals such as SUS,titanium alloy (6-4 titanium), magnesium, resin with glass(noryl, radel, ultem).
