About Us

In 1968, Diamond Chase Company entered and revolutionized the screen printing industry. Time and time again, they proved to be on the cutting edge of technology by creating products designed to make the screen printing process faster and more accurate. Products developed over the years have led to a wide and diverse product line. In 2004, Eino Products purchased the Diamond Chase line of products and continues to produce the high quality line of screen printing frames and products with the same great people that have been with the company for more than 20 years. We are the only aluminum screen printing frame manufacturer that makes an entire line of frames from the legendary draw bar frame to the roller frame to the stretch and glue frame.

Along with a stable, knowledgeable production crew, we are privileged to have dedicated and experienced key people. Alan Hamu, son of the original owner, continues to work with us on engineering, design, and product improvements along with providing technical support. Shilo Ammons is our hands on Chief Operating Officer who is your direct point of contact. Call him at 800-245-5283.
