The Carousel Rotomolding Machine is a tower-type, multi-station system designed for high-volume, energy-efficient production of hollow plastic products. With simultaneous heating, cooling, and demoulding operations, the carousel design ensures continuous production without waiting time, delivering excellent output efficiency and consistent product quality.
Key Advantages:
- Multi-station carousel design (3 to 6 stations) enables simultaneous heating, cooling, and demoulding
- Continuous mould cycle with no waiting time for maximum productivity
- Independent temperature control per station for precise process optimisation
- Hot-air circulation or infrared heating options for uniform and efficient heat transfer
- Low energy consumption per product due to optimized oven and airflow design
- Ideal for deep-cavity products such as tanks, containers, and large hollow parts
- Suitable for small to very large products, from toys to industrial tanks
Oven & Heating Technology:
- Cylindrical oven structure for high space utilisation and minimal heat loss
- Pure hot-air circulation heating (no open flame in oven) – safe and energy efficient
- Adjustable airflow volume and direction to match different product geometries
- FEA-optimised oven design for high heat utilisation and fast heating speed
- Patented anti-deformation oven door with excellent sealing performance
- Automatic oven door closing reduces heat loss and improves workshop conditions
Cooling & Production Environment:
- Large-flow negative-pressure cooling fans (air and water cooling options)
- Fast cooling cycles for increased production efficiency
- Hot air exhaust system reduces workshop temperature and improves operator comfort
Rotational Arms & Mechanical Design:
- Up to six working stations, swing diameter from 1000–5000 mm
- 3 or 4 rotational arms operating synchronously in a carousel cycle
- Independent control of moulding temperature and rotational speed (biaxial rotation)
- Straight, L, C, O and U arm configurations available for different product types
- Fully enclosed head and arm design, FEA-simulated for strength, accuracy, and long service life
- High-precision transmission and advanced lubrication system for durability
Automation & Control System:
- Modular PLC control system with Ethernet communication for stable signal transmission
- Touchscreen HMI + remote control for easier mould installation and demoulding
- All motors VFD-controlled (rotation, fans, cart movement, oven doors) for smooth, efficient operation
- Recipe storage function to save and recall product-specific process parameters
- Multi-stage heating and cooling control with real-time temperature monitoring
Smart Connectivity & Remote Support:
- Digital wireless communication technology simplifies installation and wiring
- Remote terminal maintenance module for:
- Mobile device monitoring
- Remote troubleshooting
- System upgrades
- Supports 4G, Wi-Fi, and wired network connections
Burner Options:
- Choice of Italian Riello or German Weishaupt burners
- Compatible with natural gas, LPG, diesel, and other fuels
- Customers can select based on local availability and operating preference
Typical Applications:
- Water and chemical storage tanks
- Industrial containers and bins
