Niehoff presents latest trends in multiwire drawing

September 2018 — German firm Niehoff and its Chinese affiliate will display at “wire China” 2018 an “MMH 101+RM 161” multiwire drawing line, a high speed double twist bunching machine “D 631.5”, and an “NPS SV 400 D” double spooler. 

The firm’s booth was increased by 100m² to 250m². This proves that the Chinese trade fair has become the second most important trade fair for Niehoff after the “wire” Dusseldorf/Germany. H. Folke Sandelin AB , specialized in horizontal lead extrusion and cable repair and recovery systems, will be as a sub-exhibitor.

The multiwire drawing machine “MMH 101” combined with an “RM 161” type continuous resistance annealer is designed to draw simultaneously 20 copper wires in 23 drafts from 1.8mm diameter to a minimum final diameter of 0.16mm up to 0.50mm. MMH machines are designed for copper and aluminium wires and based on a modular principle. Therefore, these machines can be built ideally adapted to the specific tasks of customers. The wires drawn on MMH machines exceed the most demanding specifications and processing requirements and can be processed to multiwire bundles with outstanding characteristics. Up to now, more than 1,500 MMH lines are in operation world-wide. 

The “D 631.5” single-bow double twist bunching machine combined with an “ARH 630” tangential pay-off, is designed for strands with a cross section of 0.09mm² to 6.00mm² and a steplessly variable lay length of 6mm to 100mm. The maximum number of twists is 6,500/min, while the maximum linear speed is 300m/min. The machine is equipped with sensor technology corresponding to the requirements of Industry 4.0 capability and enabling measurement of the preset lay length, motor and drive data, speed, and meter lengths. 

The “SV 400 D” double spooler, for a long time tried and tested in practice, is designed to operate in-line with extrusion lines and can spool insulated wires with a cross section of 0.22mm² to 6.0mm² and an outer diameter of 1.0mm to 5.0mm (including insulation). The machine is capable of accommodating all NPS 400 multiway spools with a traverse width of 100mm to 400mm and can be operated at a maximum speed of 1500m/min. Spool change is carried out automatically. By means of sensor technology according to Industry 4.0 and with the Niehoff Digital Assistant+ 4.0, machine, production and process data can be recorded.  Thus continuous process monitoring and machine condition analysis is possible.
