GLS™ TPEs - Injection Molding Guide Injection molding parameters, startup and shutdown, mold design and troubleshooting recommendations for LubriOne™ Internally Lubricated Formulations Maxxam™ FR Injection Molding

The use of 2K (two-component) molding – in which the base resin is injected and allowed to set up for a short time, and then is overmolded by injecting the TPE – streamlines the manufacturing process. It required a high temperature and a strong injection pressure to bond to the acrylonitrile-butadienestyrene (ABS) substrate, which caused the resin to deform. High-end product line = competitive advantage: With Avient’s OnFlex-S TPE, developers successfully designed and produced a new, high-end product line that compares favorably with all-plastic sprayers in terms of appearance, performance and durability.

Design and materials are intrinsically connected in the best products. It follows, then, that starting the design process with an exploration into candidate materials could legitimately be referred to as intrinsic design. And isn’t this the promise of good design at its core?

The Brooks design team knew it was up to the challenge, and they were confident they could create a breakthrough running shoe. The components and materials were carefully designed and engineered to work together properly and optimized for geometry, thickness, flexibility and performance.” Switching to Avient's GLS™ TPEs enabled Brooks to move to a single injection molding process, yielding a 30-40 percent reduction in energy usage and a projected savings of $80,000 to $100,000 annually. 

Replacing metal with PolyOne Therma-Tech™ conductive polymer enables Sylumis to manufacture the lamps more efficiently and with even more innovative designs. Transitioning from metal to specialty engineered polymer solutions helps our customers meet their goals for efficient manufacturing, innovative design and weight savings.” The specialty polymer solution from PolyOne meets relevant safety standards, including a UL94-V0 flame class rating at 3mm thickness, and offers Sylumis significant production efficiencies via injection molding in place of metal forming.

Stat-Tech TPEs can be both injection molded and extruded, giving great design freedom and enabling more complex geometries. Technical information, design guides, processing information and more. The design and lightweighting benefits of thermoplastics with the conductive performance of metal
