Terminal pins are critical components of tubular heating elements, requiring precision, consistency, and material integrity.
OAKLEY INDUSTRIAL MACHINERY manufactures high-precision terminal pins using an advanced cold-forming process that ensures tight tolerances, superior nickel retention, and dependable weld performance for high-volume production.
The first step in heating element production is precision tube cutting, which determines the final tube length and prepares it to house internal components. We offer flexible tube-cutting solutions that accommodate a wide range of production needs, supporting various cutting technologies and processing tubes from both straight lengths and coils with consistent accuracy and quality.
At the core of every electric heating element is the resistive coil, which must be manufactured with precise control over length and resistance to ensure uniform heating. OIM designs fully autonomous coil production systems featuring continuous ohmic measurement for accurate resistivity control, eliminating defects, manual corrections, and material waste. The result is a reliable, efficient process that ensures consistent quality and compliance with safety and regulatory standards.
After the coil is formed, an accurate welding process connects the coil to the terminal pins. OAKLEY INDUSTRIAL MACHINERY develops advanced coil welding systems featuring coil-pin-plug assembly units, available in manual, semi-automatic, or fully automatic configurations to meet different production demands. Powered by inverter welding technology, our solutions deliver high-quality welds, reduced cycle times, and consistent performance across a variety of industrial applications.
During the MgO filling phase, magnesium oxide is precisely introduced into the tube to provide effective insulation and thermal performance. We engineer advanced MgO filling systems designed for high filling speeds, uniform compaction, and minimal material waste. Featuring a patented three-tube flow control system and an intuitive user interface, our machines deliver consistent fill quality, optimized production efficiency, and reliable performance tailored to specific manufacturing needs.
To further increase efficiency during the MgO filling stage, the process can be fully automated through the integration of dedicated systems. OIM offers advanced automation solutions that boost production speed, reduce cycle times, and optimize resource usage. By automating the filling process, manufacturers achieve consistent, accurate results while improving overall productivity across the heating element production line.
To ensure a uniform tube diameter and further compact the magnesium oxide, the heating element undergoes a diameter reduction process. OAKLEY INDUSTRIAL MACHINERY provides advanced roll-reducing solutions engineered for precise diameter control, enhancing both thermal and electrical performance. Available with manual or fully automatic loading and unloading options, these robust systems can integrate marking, straightening, and optional electrical testing units, ensuring reliable quality control and flexibility for various production needs.
Following diameter reduction, correcting length variations requires precise dimensional control. We provide dedicated cropping, trimming, or stretching solutions to ensure accurate heating element lengths and proper terminal pin exposure, preparing each element for subsequent production stages.
Annealing is a critical heat-treatment step that relieves internal stresses and enhances the mechanical properties of the heating element. OIM offers advanced annealing systems that deliver uniform, controlled heat treatment for a wide range of materials and dimensions. Our solutions optimize the metal’s microstructure to improve ductility, strength, and formability—ensuring consistent performance and dependable results.
Automation solutions integrate multiple production stages into a streamlined workflow, boosting productivity and process consistency. OAKLEY INDUSTRIAL MACHINERY designs advanced automation systems for heating element production that reduce operational costs, maximize space efficiency, and deliver reliable, repeatable outcomes. From fully automated lines to intelligent control systems, our solutions are built for seamless integration, long-term durability, and maximum manufacturing efficiency.
Bending allows to shape electric heating elements into their final form and requires precise control over angles, geometries and single segment length tolerances. We offer advanced bending solutions for plain and finned heating elements, for 2-D, 3-D or coiled shapes, supporting both small-batch and high-volume production. From flexible semi-automatic machines to fully automated systems, our solutions ensure consistent accuracy, high throughput, and intuitive operation across diverse applications.
Finning increases the heat exchange surface of electric heating elements, enhancing heat dissipation and efficiency in air and gas heating systems. OAKLEY INDUSTRIAL MACHINERY develops state-of-the-art finning solutions for producing finned elements used in HVAC systems, industrial ovens, drying tunnels, and more. With CNC winding technology and integrated safety systems , our machines ensure consistent quality, high productivity, and dependable performance throughout the finning process.
Electrical testing ensures the safety, functionality, and regulatory compliance of each electric heating element before market release. OIM offers cutting-edge testing systems capable of performing resistance, insulation, dielectric strength, and ground continuity checks in line with CEI EN 60335-1 standards. Featuring programmable test cycles and accurate data acquisition, our systems provide reliable quality control and consistent product certification.
