Heatecx Limited
Built on an integral cast iron bed, the HTR-210 Rolling Machine undergoes a 72-hour high-temperature tempering treatment to relieve stress, granting it exceptional rigidity and resistance. This robustness guarantees stable, deformation-free operation, which is fundamental for maintaining rolling precision over time. The pressure roller spindle head, a unified structure, incorporates sliding blocks and an adjustment body cut with thread, achieving a diameter adjustment precision of 0.03 mm. It features a fine adjustment dial and a return-to-zero capability for simple calibration. The gearbox of the rolling mill motor offers differential and constant speeds, adapting to specific tube and customer requirements. The HTR-210 is compatible with a wide range of metallic tube materials and can process square, flat, rectangular, and round shapes via mold changes, offering unmatched versatility in the production of industrial electric heaters.
The HTR-210 Rolling Machine represents a significant advancement in the manufacturing of flat heaters and special-shaped oven tubes. Designed to overcome the efficiency limitations of traditional methods, this machine employs a multi-stage continuous rolling process. This approach guarantees a gradual and uniform diameter reduction, resulting in superior MgO powder compaction. The outcome is a flat heater with exceptionally high insulator density, impeccable straightness, and superior dimensional stability. The HTR-210 is the ideal tool for manufacturers seeking to maximize magnesium oxide density in their tubular heating elements, ensuring optimal heat transfer and an extended lifespan for the final product.

To adapt the HTR-210 Rolling Machine to your specific production requirements, we offer various customization options and accessories:
Interchangeable Die Materials: Availability of rolling dies manufactured from high-strength steel and cemented tungsten carbide, allowing the selection of the optimal material based on tube hardness and desired lifespan.
Advanced Control Systems: Integration of PLC with HMI touch screen for intuitive programming of rolling parameters, real-time monitoring, and storage of production recipes, optimizing the production of flat electric heaters.
Loading/Unloading Automation: Options to incorporate automatic tube feeding and unloading systems, increasing efficiency and reducing manual intervention in high-volume production lines.
Enhanced Cooling Systems: Possibility of forced-air or liquid cooling systems for applications requiring stricter thermal control during the rolling process.
Voltage and Frequency Configurations: Adaptation of the electrical system to different international standards (e.g., 220V/60Hz, 440V/60Hz) for global implementation.
Special Shape Molds: Development of custom molds to process tubes with non-standard geometries, such as oval, square, or rectangular shapes, expanding the machine's versatility and its application in industrial heaters.
Dimensional precision is the most critical factor in the manufacture of flat heaters, as it determines contact heat transfer. Our HTR-210 machine guarantees:
±0.03 mm Tolerance: Thanks to its spindle head with high-precision wire-cut sliding blocks, a constant thickness is achieved along the entire length of the tube.
Fine Dial Adjustment: Allows millimeter-level calibration to adapt to each client's exact specifications, ensuring the heater fits perfectly into grooves of thermal presses or heating plates.
Surface Uniformity: By maintaining precise thickness, "hot spots" caused by poor thermal contact are eliminated, extending the life of the heating element.
