Faster crimping of machined contacts

Currently, automatic crimping machines can be supplied with contacts in two main ways: either by separating them in vibrating bowls or by using specially prepared contact strips that are fed from a reel. The latter approach offers higher efficiency; however, until recently, only stamped contact strips were available for this method.

To address this, HARTING has developed a change unit designed for both semi-automatic and fully automatic crimping machines, enabling the processing of high-quality turned Han® industrial connector contacts on reels. A plastic belt ensures the contacts are securely held and precisely positioned during processing. Manual work steps can be eliminated, which not only significantly shortens throughput times but also increases process reliability.

Vibration feeder or vibration bowls are no longer needed to process machined contacts quickly and safely. The HARTING tool is compatible with widely used semi-automatic and fully automatic crimping machines from manufacturers such as Schäfer, Komax, and Schleuniger.

The investment in a semi-automatic or fully automatic crimping machine is especially beneficial when operations require a substantial annual volume of crimp connections. The return on investment (ROI) of acquiring the HARTING crimp change unit depends on the demand of machined contacts as well whether automatic crimping machines are already in place. HARTING experts can provide the necessary data to support your individual cost-effectiveness analysis.

The HARTING tool is capable of handling up to 34 different contact variants with cross-sections from 0.14 to 6 mm². Both the crimping tool and contact rollers are supplied by HARTING, enabling fully automated systems to achieve cycle times as short as one second including stripping and crimping. Users can not only save process costs but also personnel costs to face the challenge of the demographic change.

The new combination of high-quality machined contacts and the new crimp change unit can optimize the total cost of ownership (TCO) for all cable assemblers and manufacturers who process large quantities of crimp connections - for example, in the wind energy, mechanical engineering, automation, and railway sectors. This also benefits all other companies that already use semi-automatic or fully automatic crimping machines.
