High-Load Shuttle Rotomolding Machine from China Suppliers | Custom Factory for Large Product Production
Product Features
Shuttle rotomolding machines feature a rail-based shuttle structure at their core, typically incorporating 2-4 mold carts. These carts traverse rails between stations such as heating and cooling zones, enabling separation of heating and cooling processes to prevent energy waste.
Offering flexible operation, it suits multi-variety, small-to-medium batch production with quick mold changeovers. Its relatively simple structure keeps initial investment and maintenance costs low, though its single-batch output falls short of tower rotary machines. This makes it more suitable for producing small-to-medium hollow products.
- The oven adopts a pure hot air circulation heating method, and the hot air can be directed to the mold at an intelligent adjustment speed to form deep cavity products;
- The oven door adopts an anti-deformation structure with good sealing performance, the frequency, conversion drive is fast and stable.
- The cylindrical oven structure is designed with space utilization rate, and the oven has a small heat-absorbing area, which is energy-saving and environmentally friendly;
- Adopt the digital wireless communication technology, so the equipment installation is more flexible, the line connection of the electrical part is simple, and support remote access to all machine software for assistance;
- Each arm is equipped with a single air line dual air line is optional.
- The fully enclosed head and arm have undergone FEA simulation with high transmission accuracy，long lifetime and good lubrication system.
- Large flow negative pressure fans, including air cooling and water cooling, are adopted to achieve fast cooling speed and high production efficiency.
- Cart is controlled independently, with frequency conversion speed regulation system adopted to balance movement.
- Up to three stations, from 2000 to 8500 mm (84" to 335") swing diameter.
- Advanced rotational molding machine with less space and high load capacity;
- Central oven and one station on each side of the oven for cooling and demolding. Consecutive cycles of the same arm possible, while the other is waiting or is loading or unloading.
- The oven has undergone FEA, heat utilization simulation analysis, with high heat utilization rate, fast heating rate, energy saving and environmental protection;
- This machine is suitable for simultaneous production of products with large time differences at each molding stage.
Burner Brands
We offer two brands of burners: Italian Riello and German Weishaupt. Customers can choose according to their actual needs. Natural gas, liquefied gas, diesel, etc. can all be used on the machine.
PLC Control Solution
Modular PLC design with Ethernet communication ensures stable signal transmission, eliminating issues caused by wiring faults. HMI system featuring touchscreen + remote control facilitates mold installation/demolding, boosting production efficiency. All motors—including major/minor shaft rotation, thermal circulation fans, cart movement, and oven door operation—are VFD-controlled (smooth operation, high efficiency).
Oven Tunnel Settings
Adjustable airflow volume/direction (different product volumes require distinct airflow control).
Heating/Cooling Functionality
Multi-stage heating and cooling settings; real-time temperature monitoring; recipe storage capability to save and recall specific product process parameters.
Remote Terminal Maintenance Module
Enables mobile device monitoring of equipment status, remote troubleshooting, and system upgrades (supports all network connections, 4G, Wi-Fi, and wired connections).
