Minimac II can also be used to inspect continuous copper rod, used as feedstock in the production of wire copper strips. Rods ranging from 0.5 to 3.5mm (0.01968" to 0.13778") are tested for external defects such as scratches, dents and gaps at speeds up to 20m/s. Welding wire can also be tested, including flux core wire where missing flux can be detected as well as flaws in the wire itself. Checking continuity and locating welds in single and multi conductor insulated wire and cable are other applications. MAC engineers will be available at the stand to provide information on the company’s full range of products, including the MultiMac® eddy current tester with up to eight test channels, Rotomac® eddy current rotaries for detecting long, continuous surface seams, and ultrasonic instruments and systems. Magnetic Analysis Corp www.mac-ndt.com Maillefer Extrusion Oy 10 C22 Maillefer is promising “a convergence of revolutionary technologies” at wire Düsseldorf. The company’s live components show- case will feature a line-up covering diverse industry needs. The advanced Topography Scanner 2.0 features the latest technology for high accuracy in seamless topography scanning, while the ECH 35/45 with automatic crosshead centring provides precision in streamlining processes. Also on display will be the THC 50/90 crosshead for cable manufacturing; fibre optics FTU/FPO take-up and payoff technology, with components designed to meet production demands generated by high-speed data transmission; next generation TM1250 drop cable; and the NXW 225 extruder. The company’s aftermarket offerings include the Nomos process supervisor unit; and enhanced efficiency with automatic take-ups, featuring EKP 50/63 card rack replacement for extended lifetime and functionality. Maillefer Factory System shows the seamless integration of technologies designed to optimise production processes and enhance overall efficiency. Maillefer Extrusion Oy www.maillefer.net

M+E’s production range consists of payoffs from stationary spools or carriers; rotating payoff turntables for spools or carriers; horizontal or vertical spool payoff frames (option: double accumulation capstan); rotating capstan take-up frames for carriers (option: spiral laying, wire skin-pass, dual size capstan); and stationary capstan take-up frames for carriers (option: pattern laying, accumulation device, dual size capstan).

The Minimac II is the latest addition to MAC’s range of eddy current test instruments for detecting surface and sub-surface defects such as laps, slivers and cracks in non-ferrous and ferrous wire and rod. It features an embedded processor host computer and can be supplied with one or two test channels. Its versatility allows it to be used in a wide range of applications in wire and rod mills during production. Typical applications for the Minimac II eddy current tester include testing continuous cast small diameter copper rod – just before the coiler but after the rod is produced and drawn down to smaller diameters. The tester can assess grade using MAC’s grading software to automatically categorise the quality level of individual segments and entire coils of wire and rod during production. The user can customise the defect types, each based on a specific threshold gate; specify the maximum number of defects for each grade level; and configure categorised reports. Based on the report, the producer can draw down higher graded wire to even smaller diameters. Lower grades are not drawn down as much to avoid problems with breakage in the wire, which could end up causing downtime to re-thread the drawing machine.

Wet drawing machines with integrated spooler

It also produces horizontal or vertical spool take-up frames (option: double accumulation capstan); payoffs and take-ups for bead wire and steel cord; automatic or semi-automatic coil compacting and strapping lines; and wet drawing machines (for ultra-fine wire, saw wire, steel cord, spring wire, rope wire, staple and clips wire), complete with traditional horizontal or vertical spoolers or the newly developed series of fully automatic spoolers with no operator intervention. M+E’s daughter company’s production range consists of ultrasonic cleaning, electrolytic cleaning, HCl fumeless pickling and H 2 SO 4 electrolytic pickling, electro-plating lines, bronzing and copper coating lines, batch and in-line phosphating lines, batch and in-line coating, polymer coating, and scrubbers for fume neutralisation. M+E Macchine+Engineering Srl www.meitaly.it Madem SA 11 H25 Madem Reels Group, with headquarters in Brazil, manufactures nailed wooden reels. The group has forests, sawmill and manufacturing plants in Brazil, Spain, Bahrain, the USA, Mexico and Colombia, and produces more than 500 containers/ trucks of knock-down reels per month. Madem SA www.mademreels.com Magnetic Analysis Corp 7A F19 Magnetic Analysis Corp (MAC) will be featuring the Minimac® II at its stand at the Düsseldorf wire and Tube 2024 show.

Minimac II eddy current instrument for inspecting wire and cable for surface and subsurface defects

A magnetic inclusion detector (MID), operating in combination with the flaw detectors, can detect magnetic inclusions, often introduced by steel wire brushes during processing. In another application, a Minimac II can be installed in a wire mill to inspect zirconium, copper and beryllium copper alloys, to detect defects including surface flaws in plating and sub-surface anomalies in bonding, and inclusions in multiple layers in wire ranging from 0.838 to 6.35mm diameter (0.033" to 0.25"). A noise-cancelling test coil and bushings provide improved performance by minimising noise from mechanical vibration in the wire which otherwise might interfere with the test.
