Designs that perform.

Fusion™ Screw. New barrier screw delivers higher throughput at lower melt temperatures than earlier barrier designs. Has proven its benefits in processing polyolefins, PET, ABS and PLA in various extrusion and blow molding processes. Efficient™ Screw. This barrier screw has proven its value in more than 30 years of field experience. StrataBlend® II Mixer. Low-shear distributive mixer produces a melt of uniform temperature. It’s highly suitable for processing shear-sensitive engineering resins such as polycarbonate or ABS as well as polyolefins and materials containing high levels of colorants, fillers or glass fibers. Nano™ Mixer. Breaks up and disperses color and filler agglomerates, including nanoclays. Ideal for processing shear-tolerant materials.
