Wire Testing And Handling Equipment
Sjogren Industries manufactures wire testing and handling equipment for wire drawing, material preparation, quality control, and production setup. The product line includes powered and manual wire pointers, reverse bend testers, bench top wrap testers, torsion twist testers, and motorized die stringers. These systems help manufacturers prepare wire for drawing, evaluate ductility and coating adhesion, identify brittleness and hidden defects, and complete die changes more safely and efficiently. Available for a wide range of wire diameters, material strengths, and testing requirements, Sjogren wire testing equipment supports automotive, aerospace, medical, energy, spring wire, coated wire, and general industrial applications.

Fill The Application Data SheetPP | Powered Wire Pointer
Automated Wire and Rod Pointing for Faster Drawing Setup
The Sjogren PP Powered Wire Pointer reduces the diameter of wire or rod so the pointed end can pass through a drawing die and connect to a wire puller. A 3-horsepower drive and variable speed control from 10 to 100 RPM help operators prepare high-strength material more quickly and consistently than manual filing or grinding. Three standard roll configurations cover wire and rod diameters from 0.030 to 0.500 inches, with custom options available for specific production requirements. The mobile design, guarded rolls, and optional manual-pointer combination make the PP a practical wire pointing machine for drawing operations in wire production, automotive, aerospace, medical, energy, and industrial manufacturing.
MP | Manual Wire Pointer
Compact Wire Pointing Tool for Controlled Drawing Preparation
The Sjogren Manual Wire Pointer, also called a Hand Pointer, reduces wire diameter before the material enters a drawing die. Operators move the wire through a sequence of 15 grooves to create a consistent point without hand filing or grinding. The standard unit handles wire diameters from 0.018 to 0.156 inches and uses hardened tool-steel rolls, gear-driven shafts, and needle bearings for dependable operation. Its compact, electricity-free design allows mounting on a workbench or pedestal near the drawing line. This manual wire pointing tool suits smaller production runs, maintenance areas, sample preparation, and applications that require direct operator control.
RBT | Reverse Bend Tester
Manual Bend Testing for Metallic Wire, Coated Wire, and Flat Strip
The Sjogren RBT Reverse Bend Tester evaluates whether metallic wire, coated wire, and flat strip can withstand repeated plastic deformation without cracking, breaking, or damaging the coating. Operators secure the sample in adjustable jaws and supports, then move the bending arm 90 degrees in alternating directions according to the required test procedure. A self-centering clamp, interchangeable supports, and sample guides help maintain consistent positioning across wire diameters from 0.3 to 8 millimeters. Designed around ISO 7801 and ISO 7799 test specifications, the RBT gives wire manufacturers a compact, manual bend tester for material qualification, coating evaluation, process control, and quality assurance.
WT | Bench Top Wrap Tester
Spring Wire and Coating Adhesion Testing Through Controlled Wrapping
The Sjogren WT Bench Top Wrap Tester evaluates spring wire ductility and coating adhesion by winding a sample into a closely spaced helix around a mandrel. The completed wrap allows quality teams to inspect the material for cracks, fractures, flaking, and coating separation. An adjustable rotating chuck, sliding mandrel support carriage, wire guide assembly, and interlocked safety guard help operators control wrap spacing and inspect the sample safely. The machine handles wire diameters from 0.050 to 0.375 inches and mandrels from 0.050 to 1.5 inches. Built to support American Wire Producers Association steel-product testing requirements, the WT serves spring, coated-wire, automotive, aerospace, medical, energy, and industrial applications.
TTT | Torsion Twist Tester
Programmable Torsion Testing for Wire and Rod Defect Detection
The Sjogren Torsion Twist Tester rotates wire or rod around its longitudinal axis to reveal brittleness, inclusions, hidden seams, surface defects, and other material weaknesses. Twelve programmable twist cycles, cycle memory, automatic forward and reverse operation, and a touchscreen interface help quality teams run repeatable torsion tests with less manual adjustment. Light-, medium-, and heavy-duty models accommodate sample diameters from 0.010 to 0.750 inches, tensile strengths up to 450,000 PSI, and operating speeds up to 120 RPM. Replaceable chuck jaws provide secure sample holding, while optional linear weights and an angle bender support specialized testing requirements. The TTT meets ASTM E558 and A930 test specifications for metallic wire and rod.
MDS | Motorized Die Stringer
Safer and Faster Die Stringing for Wet Wire Drawing Machines
The Sjogren Motorized Die Stringer prepares wire leaders and strings drawing dies before operators load them into wet-draw machines. An electric pulling drum, die support bracket, thumb-release wire grip, safety cover, and hands-free foot pedal help reduce manual handling during die changes. The standard machine supports wire diameters from 0.025 to 0.188 inches and provides up to 390 pounds of pulling force. Operators can string dies away from the drawing machine, helping shorten changeovers and improve safety around the production line. Optional manual or powered wire pointers, a mobile cart, lubricant reservoir, and die-room pulling equipment allow manufacturers to configure the system around their drawing and maintenance processes.
