What Randcastle Extrusion Systems does
Randcastle Extrusion Systems is a privately held New Jersey-based manufacturer founded in 1987 by Keith Luker that designs, builds, and services bench and floor-model single screw extruders and downstream processing lines targeted at laboratory, R&D, and low-output production applications. The company's core technological proposition rests on patented mixing elements — the Recirculator (AFEM) and Elongator (SFEM) — that produce elongational, 3D flow fields in a single screw architecture, achieving dispersity reportedly 1,000x better than standard single screws and 8x better than twin screws (validated in collaborative research with Rutgers University and Dow Chemical). Supporting proprietary technologies include Surge Suppression (gear pump-class pressure stability without a gear pump), a vertical discharge-driven Microtruder design, interchangeable smooth bore feed sections, and a patent-pending Molecular Homogenizer.
The product portfolio spans Microtruders (quarter-inch to 1.25-inch screw range), cast film, sheet, blown film (up to 15-layer coextrusion), tube/wire coating, fiber and monofilament, 3D compounding and pelletizing lines, and a Micro-Batch Mixer (RM-1000-4) for 1–100 gram sample compounding. Revenue is generated through three streams: hardware sales of extruders and complete extrusion lines (quote-based), laboratory services where customers book bench time to work directly with Keith Luker on trials, and licensing of patented mixing elements as aftermarket compounding screws rated for over 1,000 lb/hr. Go-to-market is direct, founder-led sales with no dealer network; demand generation relies on peer-reviewed publications, conference presentations (SPE ANTEC, SME), and industry press. The company maintains a single headquarters, warehouse, and laboratory in Cedar Grove, NJ and operates with a very small team centered on the founder and his son Erik Luker.

Randcastle Extrusion Systems product offering
Product offeringCore offering
Randcastle Extrusion Systems manufactures bench and floor model single screw extruders (Microtruders) and complete downstream extrusion lines (cast film, sheet, blown film, tube/wire coating, fiber, and 3D compounding/pelletizing) for laboratory, R&D, and lower-volume production applications. Its equipment incorporates patented mixing elements—the Recirculator (AFEM), Elongator (SFEM), and Surge Suppression—that enable single-screw machines to deliver twin-screw-class compounding performance, with the company also offering paid laboratory trial services.
Product overview
Randcastle Extrusion Systems is a technology-driven manufacturer offering a comprehensive portfolio of bench and floor model single screw extruders and downstream processing equipment for laboratory, R&D, and lower-volume production applications. The core product line centers on Microtruders (RCP Series) — vertical discharge-driven extruders available from quarter-inch to 1.25-inch screw sizes — paired with downstream product lines including Cast Film/Coating Lines, Sheet Lines, Blown Film Lines, Tube and Wire Coating Lines, Fiber and Monofilament Lines, and 3D Compounding and Pelletizing Systems. The company's proprietary technology includes Recirculator and Elongator mixing elements that deliver twin-screw-like compounding performance from single screw designs, patented Surge Suppression for pressure stability, and interchangeable smooth bore feed sections. Supporting products include Micro Batch Mixers for small-sample compounding, Laboratory Services for customer trials, Technical Papers documenting peer-reviewed research, and Quality Control services. The product architecture is modular, allowing customers to configure systems with specific dies, downstream equipment, and patented technology elements based on their application requirements.
