KING ROTO PLASTIC EXTRUDER
Powerful Processing. Consistent Output. Smarter Recycling.
Turn production scrap and post-industrial plastic into high-grade reusable pellets for rotational moulding.
Engineered for Precision. Built for Performance.

The King Roto Plastic Extruder is engineered for efficient processing, recycling and re-granulation of thermoplastic materials for rotomoulding and other plastic-processing applications. Designed with a heavy-duty structure, precision screw and barrel assembly, controlled heating zones and reliable drive technology, the King Roto Extruder provides stable material flow, uniform melting and consistent output for demanding industrial production. The machine can be configured according to raw material, required production capacity, screw design, filtration requirement and downstream pelletizing system.
Why Choose King Roto Extruder?
Recover material value and slash virgin resin dependency with an integrated recycling cell.
Robust Engineering
Designed for stable industrial operation, high-torque plasticizing, and dependable long-term continuous performance.
Consistent Processing
Controlled screw speed, uniform heating, and steady material feeding provide total command over melt viscosity and throughput.
Recycling Focus
An ideal addition to rotomoulding plants looking to establish an in-house closed-loop scrap recovery and regranulation system.
Flexible Configuration
Extruder size, screw geometry, drive system, heating zones, filtration, and pelletizer engineered to client requirements.
Easy Operation
Operator-friendly controls simplify zone temperature settings, motor current monitoring, and line speed synchronization.
Complete Plant Solution
King Roto can integrate extrusion, pelletizing, and pulverizing equipment into a single coordinated material-preparation line.
Rotomoulding Material Recycling Process
Zero-waste circular economy: converting mould trimming flash and scrap back into certified rotomoulding powder.
Engineered for High-Performance Polymers
Efficient Polymer Processing
Precision Screw & Barrel
Custom screw flight geometries deliver controlled conveying, compression, degassing, and thorough homogenization.
Multi-Zone Temperature Control
Independent heating zones allow operators to establish precise thermal profiles tailored to varied melt flow indexes (MFI).
Variable-Speed Operation
Heavy-duty geared drive with VFD speed control allows easy tuning for dense granules, flakes, or shredded flash.
Melt Filtration
Manual or hydraulic screen changers capture un-melted impurities, foreign debris, and carbon particles before die extrusion.
Degassing / Venting
Optional vacuum vent removes entrapped moisture and volatile gases, eliminating porosity and bubbles in reprocessed pellets.
Consistent Pellet Production
Precision strand die head and rotary pelletizer produce uniform granules ready for immediate pulverizing or masterbatch blending.
The Engineering Behind The Machine.
Exact dimensions, arm loads, motor ratings, burner capacities, cycle times, and output specifications are tailored to customer factory layout, mould sizes, and throughput targets.
Standard, semi-automatic, and fully automated configurations are available based on project scope and regional plant requirements.
