MAC's Eddy Current And Elecrtomagnetic Parts Testers

Since 1928, MAC has provided a wide range of eddy current testing equipment to inspect flaws and conditions in springs, fasteners, and wire formed parts. The MultiMac® rotary and electronics along with the Varimac® and the Production Comparator (PC) are just three out of many MAC test systems. MAC has recently installed an eddy current MultiMac with a pick-and-place highly focused spinning probe rotary with high sensitivity and resolution along with the appropriate electronics. This system inspects precision ground fasteners with lands and grooves used in the automotive industry. The part is stopped inside the rotary where the “lands” are tested for seam and weld type defects. Since seams and welds run the entire length of the part, defect free product is assured. Other conditions detected include surface, subsurface, long continuous, or short defects.

Cold drawn wire is also tested with a MultiMac rotary for seam type defects and insulated cable is tested for weld type defects including splices.

Fasteners, wire, cable, and other parts may be tested for alloy variations, hardness, heat treatment, case depth, geometry, cracks and other conditions using the Varimac or the PC. The part is placed in a vibratory or rotating bowl which feeds the parts through the tester coil and into the parts gate which can sort the parts into 2 or 3 categories: accept/reject; below; within, or above the designated level. Speeds can be as great as 6 parts per second.

Custom eddy current, ultrasonic, and flux leakage systems are also available for special conditions and components.
