Pelletizing System for Engineered Resins and Recycled Materials for Optical Molding

Matsui America is introducing the Raptor22 pelletizing system. According to Matsui, the system enables the reuse of engineered resins in critical molding applications — a use case which has not been possible with currently available technology.

The Raptor22 has a proprietary screw design that prevents carbonization and eliminates material shear heat. It also has a carbide rotating blade that cuts the hot material strands at high speed, producing round, teardrop-shaped pellets. Finally, a vacuum-based conveying system cools the material as it is being transported to a cyclone receiver.

The use of a Raptor 22 pelletizing system makes it possible to process and reuse highly engineered recycled materials like LCP, COC, COP, PC, PA46 and PEEK, among others. A system configuration including the integration of Matsui’s recently introduced molding defect elimination products with the Raptor enables the use of recycled materials, even for optical or cosmetically critical molding applications. Matsui’s static eliminator, for example, removes material in powder form, eliminating black and white spots, burning and uneven blending and weighting.

“The Raptor 22 pelletizing system helps our customers to save significant material and operating costs with the ability to recycle and reuse extremely expensive materials like LCP, PEEK, among others. Additionally, our technology contributes to sustainable plastics use by reusing some of these materials instead of sending them to a landfill,” says Mike Kott, GM of business development at Matsui America.

The Raptor 22 produces clean and uniform pellets, with very little deterioration of physical material properties. It also features intuitive control technology and HMI, as well as an energy-efficient design.
