Union Tube™ is a product made completely from photo etching. Kyosei is dedicated to improving and advancing traditional photo etching techniques. Our research has led us to develop a unique method in order to apply photo etching towards 3D material such as tubes. This allows for us to make various slits, holes, tapers and more on a rounded surface. Finished products include catheters, stents, spiral tubes and much more depending on the customer's requirements.
