The HTC-12 Rolling Machine is a state-of-the-art engineering solution for the manufacturing of cartridge heaters and other tubular electric heaters. Its primary function is to compress the tube diameter to increase the density of the MgO powder, a crucial step that significantly enhances the thermal conductivity and dielectric strength of the heating element. This MgO densification process ensures more efficient heat transfer from the resistive wire to the metal sheath, extending the heater’s lifespan and optimizing its energy performance. Built on an integral cast iron bed, the HTC-12 guarantees exceptional stability and durability, having undergone a 72-hour high-temperature tempering treatment to eliminate internal stresses and ensure reliable long-term operation. It is an indispensable tool for manufacturers seeking maximum quality and efficiency in their industrial heaters.
The design of the HTC-12 Rolling Machine focuses on precision and ease of use. Its pressure roller spindle head, an integral structure, incorporates sliding blocks and an adjustment box body cut with threads to achieve a rolling precision of up to 0.03 mm. It includes a fine tube diameter adjustment dial, allowing for simple calibration and a return-to-zero function for future adjustments. Furthermore, the rolling die's R-groove is equipped with an automatic scrap removal device and an oil drip cooling system, ensuring clean operation and prolonging tool life. The gearbox of the rolling mill motor allows for constant speeds adapted to the tube diameter and customer needs, guaranteeing excellent extensibility of the rolled tube. This machine is compatible with a wide range of metallic tube materials and can process round, flat, and other shapes via mold changes, offering unparalleled versatility in electric heater production.

The HTC-12 Rolling Machine is fundamental in the manufacturing of a wide variety of heating elements where insulator compaction is critical for performance and durability. Its main applications include:
Cartridge Heaters: Essential for the production of cartridge heaters used in injection molds, plastic extrusion, hot plates, and packaging machinery, where high power density and efficient heat transfer are required.
Tubular Heaters: Used in the manufacturing of tubular heaters for liquid, air, and surface heating, guaranteeing optimal insulation and a long lifespan in demanding industrial environments.
Immersion Heaters: Contributes to the quality of immersion heating elements employed in tanks, water heating resistors, boilers, and chemical processes, where moisture resistance and efficiency are paramount.
Appliance Heating Components: Ideal for the production of high-quality heating elements for appliances, such as ovens, stoves, and water heaters, where safety and energy efficiency are key.
To adapt the HTC-12 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.
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.
It is a physical rule in metal forming: "the smaller the diameter, the greater the length." Because the volume of the tube material and MgO remains constant, the reduction in diameter causes a displacement of the material towards the ends.
Predictable Elongation: In a precision machine like the HTC-12, this elongation is uniform. Manufacturers must calculate a "stretching factor" to cut the initial tube shorter than the final desired measurement.
Density Control: If elongation is not controlled, MgO density could become uneven. The HTC-12 roller system ensures that stretching is constant along the entire length, maintaining uniform power density in every centimeter of the heater.
