for copper wires, and is operated by means of the standardised NMI (Niehoff machine interface), a network compatible touchscreen that enables intuitive operation. The intelligent technology of the machine allows it to measure, save and use machine data, production data and process data according to Industry 4.0. The D 632 double twist bunching machine was built by NMC under Niehoff licence. With a single-bow design in combination with the energy-saving Eco-Bow, the machine is claimed to consume less energy during operation than conventional one- or two-bow bunchers. It also allows a reduction in material usage, because it produces strands with very tight tolerances, so only the minimally required copper cross-section is used. The NBAT opto-electronic traverse system and the precise functioning of the machine enable one operator to control multiple machines. The spools are perfectly filled due to the regulated wire tension, regardless of the spool filling. The D 632 is suited to processing copper alloy fine wires such as CuSn0.3 into bunches for automotive wires. Using the “stretch forming and straightening technology”, the D 632 avoids the crowning and spiralling effect typical of certain copper alloys. The maximum production speed is 300m/min, and the strand cross-section ranges from 0.09 to 6mm².

In 2022, MFL Group also acquired Coseco, a specialist in lines for the electrolytic coating of copper wire (tinning, silvering, etc); plants for the continuous pickling of welded tubes in stainless steel; plants for regenerating sulphuric acid; and other auxiliary equipment. This addition to the portfolio enables the group to provide turnkey solutions for solar photovoltaic cable manufacturers. The production line for solar cables is a complex system that involves several machines working together. In its portfolio, MFL Group has all of the machinery required to go from raw material to the finished cable.

Rosendahl Nextrom GmbH Stand: E1 D43

Rosendahl Nextrom will showcase its latest manufacturing solutions for cable and wire, optical fibre and shock tubes, with a special emphasis on equipment and processes for the production of datacom and high-voltage cables.

Rosendahl Nextrom will promote its equipment for cable, wire and optical fibre

Visitors will be able to explore how the company’s equipment and processes for metal communication cables can enhance product quality while optimising material usage and energy consumption. For high-speed data cable production or customised processes for specialised metal cable applications, the solutions can deliver efficiency and stability. With high demand for electricity and the expansion of renewable energy sources, power transmission systems are becoming increasingly important. Rosendahl Nextrom can provide specialised machinery for manufacturing high-voltage cables for challenging environments. The company’s metal tape-forming and welding line with subsequent jacketing is suitable for a wide range of applications, from power cables for subsea and underground use to power cables for factory environments, wind farms or photovoltaic power plants. Almost any cable that requires a robust metal shield can be produced on the line, making it a highly adaptable solution for various industries.

The production of solar cables is a specialised process that requires advanced and reliable machinery

The typical production process starts with a Frigeco rod breakdown machine, followed by a tinning line from Coseco. Once the wires have been tinned, they are passed through a multi-wire drawing line, and then through the double stranding machine. After that, the Frigeco extrusion line for solar cable comes into action.

Maschinenfabrik Niehoff Stand: E1 F23

D 632 double twist bunching machine

Maschinenfabrik its Chinese subsidiary Niehoff Machinery Changzhou Co, Ltd (NMC) will display an MMH 121 multi-wire drawing machine; a D 632 double twist bunching machine; and a BMV 24 braiding machine. The company’s after-sales service will also introduce its offer of spare parts with the “Niehoff Original+” label. These products help increase the efficiency of Niehoff systems over the long term. The MMH 121 multi-wire drawing machine is designed to draw 32 wires on two levels simultaneously, with high productivity (up to 35m/s), a low wire break rate and energy-saving operation. The machine is expected to be used Niehoff and

The BMV 24 vertical lever-arm rotary braider with 24 bobbin carriers has several special features. Multiple monitoring systems enable unattended operation over longer periods of time and without frequent operator intervention. It is designed for the processing of bare or plated round or flat wires made of copper, aluminium or stainless steel with a cross section of 0.02 to 0.56mm² (for Cu soft), as well as artificial yarn and fibres.
