Automatic Rotary PU Curing Oven for Air Filters
Industrial-grade automatic rotary PU curing oven designed for high-efficiency thermal curing of polyurethane filter end caps and frames. Features 60 stations, variable-frequency rotation speeds, and precise digital temperature control. Once the PU adhesive is precisely cast using our Automatic Polyurethane PU Gluing Machine, the filters are transferred to this circular line to complete a highly uniform, automated curing cycle before final inspection.
This high-efficiency Automatic Rotary PU Curing Oven is a specialized thermal processing system engineered for the rapid, uniform curing of polyurethane (PU) foam adhesives after they are cast onto air filter end caps, panel frames, or industrial cabin filter elements. By circulating heated air along a continuous closed-loop turntable conveyor, it accelerates the chemical cross-linking and polymerization of PU resins, significantly shortening the manufacturing cycle.
Equipped with a 60-station circular turntable, digital multi-zone heating controls, and stepless variable-frequency speed regulation, this curing oven eliminates the bottleneck of manual filter handling and drying. It is the ideal auxiliary equipment for medium-to-large-scale air filter assembly lines, ensuring that every finished polyurethane air filter achieves a perfect hermetic seal, consistent elasticity, and high structural durability.

Key Features & Mechanical Advantages
1. Fully Automated 60-Station Closed-Loop Workflow
The machine features a continuous, heavy-duty circular turntable conveyor equipped with 60 independent processing stations. Operators only need to load the uncured, freshly glued filters at the loading station. After completing one full rotational cycle through the heated chamber, the fully cured, ready-to-pack filters return automatically to the same operator, eliminating labor bottlenecks.
2. Rapid Curing and Uniform Heat Distribution
Built with a highly insulated thermal curing chamber and a precise air-forced circulation system. By providing constant, uniform heat distribution (ambient up to 150°C) across the circular path, it reduces the PU adhesive curing time from the standard 30+ minutes at room temperature down to under 10 minutes.
3. Stepless Variable-Frequency Speed Regulation
Driven by a high-torque motor managed by a variable frequency drive (6–20 min/rotation), the rotation speed can be adjusted infinitely. This allows workshop managers to synchronize the curing cycle perfectly with the cycle speed of the preceding PU glue injection machinery.
4. Intelligent PLC & Centralized HMI
The centralized control panel enables real-time adjustments of conveyor rotation speeds, precise multi-zone heating temperatures, and pneumatic positioning pressures. Built-in alarms and temperature fluctuation monitors ensure high-repeatability and maximum operational safety.
