What performance factors drive your preference for aluminum or steel in part design? Engineered polymers and specialty composites are gaining popularity because they can achieve metal-like performance while providing design flexibility through injection molding. The outstanding performance-to-weight ratio combined with the ease of injection molding, fewer secondary processing steps, and complete design freedom can aid automotive engineers in many applications.

Homepage // News Center // Comfort Meets Design Freedom in New Overmolding Solution from Versaflex™ VDT Vibration Damping TPE Portfolio Customers familiar with our Versaflex VDT material have asked for an overmolding variation that allows them to leverage the design freedom of two-shot and insert injection molding,” said Charles Page, director, global marketing, PolyOne GLS Thermoplastic Elastomers. Versaflex VDT overmolding grades deliver the same great vibration and impact damping performance as the original Versaflex VDT technology, exceeding most thermoset solutions while offering the advantage of thermoplastic design flexibility.

HVAC doors are typically produced by injection molding two parts that provide structural strength and air sealing performance. However, in this case, designers wanted to reduce the thickness of the part wall significantly to achieve a relative weight saving of 90 percent. Designers were able to achieve a relative weight saving of 90 percent without compromising performance.

When PolyCase Ammunition was getting ready to produce its new line of high performance ammunition, the project team knew they needed a material that would be easily enable them to produce their patent-pending, injection molded projectile designs that function as well or better than conventional lead-core projectiles.  The designs were unique. The Avient team used their extensive knowledge and experience working with high-density polymers to develop a specialized Gravi-Tech™ high-density polymer composite that met PolyCase’s needs and fit the profile of their proprietary injection molding process.

Reusable concentrates significantly reduce time spent cleaning extrusion and injection molding equipment. Technical information, design guides, processing information and more. Reusable concentrates significantly reduce time spent cleaning extrusion and injection molding equipment.

Their flowability, combined with injection and impact strength, make them a good fit for complex thin-wall moldings while also providing design and processing freedom. We identified a growing need for high-density injection molding solutions that will help brand owners, designers, and manufacturers create weighted premium products with more complex designs than possible when using metals, while simultaneously meeting higher demands on impact strength,” says Matt Mitchell, director of global marketing, Specialty Engineered Materials at Avient. As injection molding materials with good flowability, they deliver finished components in one single process step, helping to facilitate easy assembly.”

PolyOne proudly accepted this challenge and collaborated with the nonprofit's founder, Kevin White, to design a simple and effective device specially designed for use in under-resourced communities. Designers Brian Everett, Jane Spikowski, and John Church of PolyOne’s IQ Design team donated design time and expertise to help White, executive director of GV2020, develop his invention, a diagnostic device called the U-See™. PHOTO CAPTION: PolyOne’s IQ Design team assisted with the design, moldfilling analysis, and production of the injection-molded USee device, which includes a copolyester frame, medical-grade polycarbonate lenses, and acetal for the dials and gears.
