Cable processing - Import export

Metzner has a clear understanding of the future and transforms existing processes into fully automated system solutions. Workstations that were previously operated separately are now combined into fully automatic production lines. The starting point of an automatic processing line is the cable that is wound on a reel. The end result is a finished cable with a completely assembled plug system

The EM 600 can integrate up to six successive process tools in one single station. After insertion, the cable remains in a fixed position while the tools move towards the cable to provide optimum protection for the HV cable wires. The total cycle time of an EM 600 station is approx. 35 seconds for all operations of this station, with a total capacity of approx. 400,000 cable ends per year.

The specially developed production line can unwind, label, roughen, cut to length, strip, wind, bind and automatically deposit the cable wires. The material to be processed is unwound by a motorised unwinder and fed to a thermal transfer printer via a straightener. The latter prints the cable with two QR codes and a serial number. This ensures that each cable can be identified throughout the entire processing and manufacturing process and assigned to the stations which have already passed through. This traceability offers great advantages – for example in the diagnosis of faults. The cable then passes through a roughening station, which lightly roughens the material surface so that the connector overmoulding adheres better later on. An AM 3550 from Metzner Maschinenbau cuts to length and strips the cable, which is then transported to the winding station and onwards by a gripper to the binding machine. The latter winds the cable to form a cable ring.

Electrical cabinets contain the electrical and electronic components of a process engineering system, a machine tool, or production equipment that is not directly located in the machine. They are manufactured by special switch cabinet builders or by the machine manufacturers themselves. To save costs, there are automation solutions that are not only worthwhile for large production series, but are also suitable for the more efficient and economical production of individual and small series. Metzner offers a unique and comprehensive system solution to reduce your expenses in switchgear construction. Depending on your requirements, different stripping and crimping machines are available, which differ in terms of design, performance and degree of automation. METZNER TRIATHLON SERIES - for precise cutting to length and one- or two-sided stripping - for crimping the ferrules (single- and double-sided) - for individual labelling of strands with different printing method

This special Metzner development is able to process cable wires with a diameter of up to 28 mm. The cycle time for this is 2000 mm / 35 seconds. The processing steps include long slitting, sawing, circumferential cutting, stripping, brushing and depositing. An integrated ink jet printer labels the cable wires with information or markings. As the heart of the processing method, Metzner uses a newly developed stripping head that combines a rotary cut with a powerful clamping and simultaneous rotation of the material. This enables a high-precision, multi-stage radial cut through the various layers of material. Microscopic quality inspection confirms that the processing is flawless with no scratches, pressure or abrasion marks. In addition to the high machining quality, the machinery also offers special precision: both the overall length and the machining position are maintained with an accuracy of 0.2 mm. The machine can process cable wires with diameters up to 28 mm.

The AM 3000 range of cable processing machines are distinguished by cutting and haul-off power and their convincing modular, robust and long-life construction for continuous industrial working. There are different models with different cutting powers and specifications. To match the processing requirements, numerous knife contours and technologies are available: The patented „ double-knife system“ facilitates different processing in a single working pass, the circumferential rotary technology offers exact circular cutting for cables with very thin or rigid outer insulation cover and for co-axial cables. Every model is equipped as standard with a full set of interfaces for peripheral equipment and IT integration. The machines can easily be converted into complete production lines, thus further increasing the process automation.

Metzner offers low-cost individual stations in the field of e‑mobility for the entry into high-voltage cable processing. For the first time, the EM 101 module offers a solution for removing the cable foil without affecting the cable shield. The automatic processing of high-voltage cable wires also necessitates the connection of various components of the connector system. The Metzner EM 102 takes care of this. The EM 103 allows the cable shield to be opened and cut using a patented process which ensures that there is absolutely no contact with the inner insulation. The EM 103S offers the functionality of the proven EM 103 to meet the requirements of smaller cable wires of up to 8 mm diameter. These cost-effective models cannot be integrated into an automation line and are equipped with only limited traceability functions.

The Metzner EM 300 platform offers further convenience in high-voltage cable processing through a quick change of process tools and faster cycle times. Depending on the requirements, the HV cable processing machine can thus be equipped with different tools for cable processing. This means that the EM 300 can be used for several processing steps and is prepared for a wide range of processes. In addition, with the EM 300 we protect your investment by offering improved expandability that enables “plug-and-play” integration of future new applications.

Metzner has developed a fully automatic processing machine with outstanding cutting quality and great length accuracy for steel cable wires of up to 20 mm diameter. The steel cable wires are fed by a motorised feeding device in combination with a contact-free loop control. Then, program-controlled and positionally accurate marking tapes are applied to the steel cable – with a cycle time of less than two seconds. In addition, a wax printer marks all the fastening and processing points that will be required for subsequent processing. This labelling method is carried out in a continuous process. The cut is then made using a special cutting process. Precise length accuracy is achieved by a special laser measuring system. A material stacker with a storage area of up to 12 metres ensures that the steel cable wires are deposited in an orderly manner. All cut steel rope can be stored and sorted according to length to allow it to be removed at a later point.

The Metzner AM 5000 range includes the flagship models for precise processing of thick cables up to 240 mm² section and 35 mm diameter. Even the basic specification models, with their high torque and powerful three-stage step motors offer the highest level of cutting and haul-off power. All models are equipped with as standard with the Metzner double-knife system that enables very varied and multi-stage processes to be performed. Moreover, with convincing operator-friendliness and long service life. Metzner AM 5000 models are also suited to processing thinner braided cables from 1.5 mm² The stripping full haul-off 1side/2nd side amount to 270-450 mm and 90-270 mm, for partial haul-off 450 mm and 270 mm. For interuption-free automatic production, a number of sensors monitor the material feeding If a material blockage occurs, the production stops automatically and the operator is informed about the cause of the fault.

The Metzner AM 1000 is a sensation among the tabletop units. The automatic cutting and stripping machine processes cables, strands and wires up to 9 mm diameter and 6mm² cable cross-section with a special cutting and pull-off force (optional 10 mm², depending on material). The presettings are conveniently made via the modern 12" touch panel, where the operator can define all processes. Thanks to the sensors for diameter and material recognition, the AM 1000 works extremely precisely. Another special feature is the tool-free replacement of guides and rollers. This means that the AM 1000 can be changed over in just one minute. With the extensive interface preparation, the machine can be optimally expanded with peripheral devices and adapts to all customer requirements. The compact design with retractable touch-screen and the low weight of only 28 kg also offer special comfort. This makes the AM 1000 especially easy to transport.
