-Challenge Accepted-

At Randcastle Complete Extrusion Systems, we manufacture bench and floor model single screw extruders for laboratory, R&D, and lower output production applications. Unique features include patented compounding technology elements (The Recirculator) with twin like performance. Studies show nanopowders compounded at 50,000 x, wood sheet in one step up to 40% incorporation and more. Surge suppression, a patented Randcastle process has shown gear pump pressures (plus/minus 10 psi) without the expense and trouble.

Randcastle features unique interchangeable feed sections, discharge driven screws for small extruders and conventional horizontal extruders, and a host of downstream products. We lead the industry in product turn around time, receptibility, reliability, and quality. Randcastle is proud to be an active research facility. Keith Luker leads our laboratory team and they love a good challenge. Contact us with your projects and we will help you sort it out. We love making science happen and are passionate about pushing the boundaries of extrusion technology.
