In heating elements production, laminated elements can show length variations of up to 2%, affecting the accurate distribution of dimensional tolerances. Oakley Industrial Machinery’s stretching machine for heating elements is designed to compensate for these differences, optimizing the rolling mill process and ensuring maximum precision in the final product.
Built with a simple yet robust construction, the machine requires minimal maintenance while enhancing the straightness of heating elements. Ideal for heat-treated heating elements, the stretch-to-length machine supports medium to large production batches and integrates seamlessly with Oakley’s automation solutions to streamline operations.
The concrete advantages that make the difference
Intuitive controls and minimal maintenance make it ideal for continuous production.
Capable of processing a wide range of tubular heating elements efficiently.
Improves post-drawing linearity, directly benefiting the quality of annealed tubes.

ELECTROPNEUMATIC UNLOADING DEVICE
to discharge the elements after the stretching cycle.
PNEUMATIC CLAMPS
to secure the elements during stretching.
WELDED AND PAINTED STEEL FRAME
for the working units.
2 HYDRAULICALLY ACTUATED UNITS
to stretch the heating elements.
ADDITIONAL STATIONS (NOT INCLUDED)
It is possible to add one optional station to automatically perform an additional operation on the machine, such as: electrical testing, cropping terminal pins to length, cleaning terminal pins, and electropneumatic unloading of the element from the additional station.

It is possible to add a single additional station to the machine to perform an extra automated operation, such as terminal pin cropping. This is achieved using electropneumatic units with a rotating mandrel and the appropriate tooling.
It is possible to add a single additional station to the machine to perform an automated operation, such as electrical tests. This station can include an ohmic value measurement instrument (mod. 232/00), a dielectric strength tester (mod. 232/10), and a pair of pneumatically operated contacts.
