End Finishing and Stretching Transfer Machine for Tubular Heating Elements

The end finishing and stretching transfer machine is a fully automated system designed to perform the final processing operations on tubular electric heating elements within a single continuous production process.

The machine integrates terminal pin cutting, quality inspection, end deburring, stretching to final length, and electrical testing, bringing every heating element to the required specifications before assembly.

Thanks to its modular design and automated process management, the transfer machine ensures high productivity, consistent quality, and maximum production flexibility, processing heating elements of different lengths without requiring mechanical retooling.

Advantages

The concrete advantages that make the difference

Maximum flexibility without mechanical retooling

Format changes are managed simply by adjusting the machine parameters, allowing different heating element lengths to be processed without mechanical changeovers and minimizing setup times.

Multiple operations in one automated process

Pin cutting, end finishing, stretching, electrical testing, and unloading are performed sequentially within a single machine, simplifying production flow and reducing part handling.

High productivity with continuous quality control

Integrated sensors and monitoring systems continuously supervise every stage of the process, ensuring precision, repeatability, and reliable performance even in high-volume production.

Details

The automatic end finishing and stretching transfer machine is designed to complete the final manufacturing stages of tubular electric heating elements, from terminal preparation through to electrical testing of the finished product.

The machine consists of sequential workstations, synchronized by a transfer system that automatically moves each heating element throughout the entire production process.

The stations include:

  • Manual loading: the operator loads each element into the machine
  • Pin cut-to-length unit: crops the terminal pin to the required length
  • Cut inspection unit: verifies that each pin cut meets the specified quality and dimensional standards
  • Chamfering unit: chamfers the pin end for a clean, assembly-ready profile; supplied as standard for smooth pins (roll-forming), and can also be equipped with tooling for threaded pins, which removes part of the cut pin end by machining and re-chases the thread
  • Stretching-to-length unit: stretches the element to its final calibrated length
  • Electrical testing unit: performs electrical checks on the finished element
  • Automatic unloading unit: unloads finished elements automatically at the end of the cycle
