Fiberglass shafts were typically sourced from Asia and produced using a traditional mandrel rolling process, which slowed production and limited Carbonerro’s design freedom. THE SOLUTION The Avient technical support team got involved early in Carbonerro’s design process of the Proglas shaft. Furthermore, by moving production of the shaft to the U.S., the company gained control of product design, ensured part consistency and shortened cycle times.

In addition, the design included more traditional features, such as four small support feet on the underside of the mouse for low-friction, easy-glide operation. Its design team determined the need for a soft-touch material with strong chemical resistance and color stability for the mouse grip. For the mouse feet, Avient formulated a special grade of LubriOne™ filled acetal as an improvement over the neat acetal found in traditional designs.

Avient uses a “systems approach” to develop the laser welding solution most adapted to your project, taking into consideration the following aspects: • Transmitting and absorbing parts • Polymer type and grade • Dispersion of the additive in the final part • Sufficient and consistent loading of the additive • Part design: attention to flow separation at the welding interface • Color and opacitiy • Quality control – e.g. establish suitable control parameters (UV Visible Spectra) • Laser wavelength and processing parameter Mevopur™ Healthcare Functional Additives formulated for laser welding are designed for use in healthcare applications. Please be aware that there are certain applications Avient’s Mevopur products have not been designed for, nor are they promoted or intended for use in: including, but not limited to long-term or permanent implants, birth control devices, or plastic surgery.
