Explore our top-tier shuttle rotomolding systems, eco-friendly electric ovens, lab polymer test units, and CNC-machined steel moulds designed to meet strict European CE standards.
Shuttle type rotational molding machines represent the global standard for industrial versatility, modular scalability, and complex hollow-part polymer fabrication. Unlike fixed-cycle carousel systems where every arm is inextricably synchronized to a single cycle tempo, the shuttle architecture functions via independent linear carts that shuttle on high-precision ground rail systems into a centralized, high-efficiency thermal chamber. This decoupling allows concurrent processing of vastly divergent parts—such as a 20,000-liter multi-layer cross-linked polyethylene (XLPE) chemical tank on Arm A requiring a 45-minute heating cycle, alongside an intricate automotive ventilation duct or insulated cooler box on Arm B requiring only 14 minutes.
Core Thermodynamic Advantage: StarWayRoto shuttle machines integrate forced-convection hot air circulation matrices driven by balanced centrifugal blowers and modulating burners (natural gas, LPG, diesel, or zero-carbon electric ceramic elements). This achieves internal chamber thermal equilibrium within ±2.5°C, radically diminishing part warpage, uneven wall thicknesses, and ungelled resin residual stress.
Every shuttle frame fabricated at StarWay Roto undergoes stress-relieved thermal annealing to prevent long-term structural fatigue under continuous cyclic loads exceeding 15,000 kg. High-torque biaxial transmission gearboxes utilize hardened helical gearing with variable frequency drives (VFD), allowing minor and major rotation speeds to be adjusted dynamically between 1.0 to 20.0 RPM at ratios ranging from 1:1 to 1:8. This precise kinematic control enables optimized resin flow vectors across intricate mold cavities, undercuts, and molded-in structural inserts.
Featuring rock wool high-density insulation panels (150mm to 200mm thickness), stainless steel internal ducting, and top/bottom adjustable damper air nozzles for uniform aerodynamic hot gas envelopes.
Equipped with Siemens S7-1500 / Schneider PLC architectures, intuitive HMI touchscreens, remote telemetry modules, and real-time internal mold temperature (K-KORE) integration.
Built in uncompromising compliance with the European Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and EMC Directive 2014/30/EU.

Our shuttle rotomolding machines are fully certified under the European Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and Electromagnetic Compatibility Directive (2014/30/EU). Gas combustion trains adhere rigorously to EN 746-2 standards for industrial thermo-processing safety, including double solenoid shut-off valves, gas pressure monitoring switches, and certified burner management relays.
A shuttle machine provides 100% operational independence between the two carts. In a job-shop environment where mold sizes, wall thicknesses, and resin types vary widely, Arm A can run a thick 20,000L tank (45 min heating) while Arm B runs smaller parts (15 min heating) without either arm forcing downtime on the other. Shuttle machines also feature a lower initial investment and smaller linear layout footprint.
Our machines process the full spectrum of rotomolding-grade polymers: Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE), Cross-Linked Polyethylene (XLPE), Polypropylene (PP), Polyamide (Nylon PA6/PA11/PA12), Ethylene Vinyl Acetate (EVA), and specialty fluoropolymer compounds. Precise multi-stage recipe temperature control prevents polymer degradation.
We configure ovens for Natural Gas, Liquefied Petroleum Gas (LPG), Diesel, or Zero-Emission Ceramic Electric Heating. Thermal efficiency is maximized via 150–200mm high-density rock wool thermal insulation, high-velocity recirculating airflow ducting with balanced draft nozzles, and automated pneumatic chamber door compression seals.
