Round wire, flat wire, coils & special applications

Winding

Our winding technology is the ideal solution for the production of solenoid valves, relays, transformers, antenna coils and loudspeaker coils.

Due to the modular process structures, our winding technology is also optimally suited for many special winding tasks, such as centrifuge windings, hollow capillary and flyer windings.

Round wire

In the last few years, we have been increasingly approached by our customers about round wire winding. This motivated us to develop the modular HWS-3000 and HWS-4000 multi-spindle winding machines. In particular, in conjunction with further automation and processing steps, such as bending, stripping, embossing and testing processes as well as integration and interlinking with other LJU products, e.g. the robot cells and rotary indexing tables.
Here, LJU benefits from the uniform and compatible control structure and comprehensive production and manufacturing expertise.

Upright flat wire

Flat wire winding is one of our core areas of competence, which we can optimally expand with further automation and processing steps, e.g. bending, stripping, embossing and testing processes as well as integration and interlinking with other LJU products, e.g. the robot cells and rotary indexing tables.

Here, LJU benefits from the uniform and compatible control structure and comprehensive production and manufacturing expertise.

Centreless coils

The winding of centreless coils at highest precision can be carried out on our UWM, HWM etc. type winding machines.
Here, too, we offer our customers not just a winding machine, but an overall concept.
For example, special coils in the acoustic and automotive sectors are not only wound in the correct position, but also baked, glued, bent, stripped, soldered, welded, measured and/or further processed inline or offline.

But also simple centreless coils, e.g. trip coils with and without bends, can be produced efficiently with optimised cycle times on standard machines.
Here, LJU benefits from the uniform and compatible control structure and comprehensive production and manufacturing expertise.

Bi-metallic coils

For many years, LJU has been optimally positioned for the winding of bi-metallic coils with the UWM 8000-Bi. This machine can be supplied as a manual operator version or as a fully automatic version with belt system and interlinking to follow-on processes, automatic insulating jacket, as well as embossing, welding and palletising.

Here, LJU benefits from the uniform and compatible control structure and comprehensive production and manufacturing expertise.

Special applications

Special applications represent a particular strength in the field of winding technology. Here, we benefit from over 20 years of experience and a modular construction system for winding components. This has enabled us to successfully realise many new applications in the medical, automotive and consumer sectors.

LJU Sondermaschinenbau GmbH has been able to gain a lot of experience through demanding winding tasks in the field of capillaries and Bourdon springs and has thus been able to develop corresponding machines for well-known manufacturers of measuring technology.

A particular strength of our winding systems lies in their flexibility. Special windings in a wide variety of designs are possible; the customer advantage here is the internal linking of all subsequent processes, e.g. fitting of core assemblies, soldering, welding, bending and finishing as well as various testing processes including palletising.

One of our special solutions is the winding system for the medical sector, for example our system for winding and soldering copper tubes on stainless steel pots used in the production of centrifuges.  The simultaneous winding and joining of the copper tubes on the centrifuge pots without leaving annealing colouration on the inside was the special challenge here.
