When engineering devices with medical applications, it’s critical to keep patient safety at the center of all design choices. Fortunately for the engineers working on medical components, polymers combine the favorable properties of glass and metal with unique properties that create better, safer components. As a result, increased use of polymers in medical applications –…

When a project calls for optically clear or smooth components, it’s simple to turn to glass or quartz as a material solution. However, while either material will produce an optically clear or smooth product, polished plastic may be the better choice. Polished plastic offers all the benefits of plastic polymers. It offers durability, lightness, or…

When your manifold or precision component project is in its early stages, material selection is just as critical to success as the design itself.  Unfortunately, narrowing down your options to the ideal choice can be challenging.
