Electric Heating Rotomolding Machine (Oven) from China Suppliers - Safe, Eco-Friendly Factory Solution
Product Features
Electric-heated rotomolding machines utilize electrical energy as their heat source, with precise temperature control as their core feature. Through electric heating elements, temperatures can be maintained with an accuracy of ±5°C, accommodating diverse plastic melting requirements. Operating without open flames or exhaust emissions, they are suitable for indoor production without requiring ventilation systems. The equipment features a streamlined structure for easy operation and maintenance, and incorporates over-temperature and leakage protection for enhanced safety.
- Energy saving and environmental protection, no waste gas emission.
- Can accurately control the mold temperature and control the product molding quality;
- High degree of automation, access to smart factories;
- Operation is convenient, and covers a small area of land;
- Suitable for the production of high value-added products.
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) optimizes temperature distribution inside the heating chamber.
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).
