Reverse Bend Tester
Quality Testing For Metal Wire and Strip
A Simple, Lightweight Solution For Bend Testing Metal Products To Ensure Integrity Of Metal Wire, Cable, As Well As Other Metal Products And Their Coatings
Product Overview
The Reverse Bend Tester is used in the wire industry to determine the ability of metallic wire, coated metallic wire, and flat strip to undergo plastic deformation during reverse bending.
The RBT from Sjogren provides a simple solution to the bend testing process. It is operated by pivoting the bending arm back and forth 90˚ while the material being tested is positioned in adjustable jaws and sample supports.
This will test cracking or deformation of the coating on the wire to ensure quality is up to your specifications and the RBT from Sjogren was designed based on ISO standards for metallic material testing.

Reverse Bend Testing FAQ
How do I know what length to test of my wire or strip?
Length and testing requirements will be set by you or your customer. The wire or strip being tested should be the straightest possible as to not sway any results.
What if my test piece is not straight?
A test piece that is not completely straight is going to impact your results. It is recommended to straighten your test pieces completely using either a wire straightener, or going the tried and true way of hammering on a level surface such as wood, plastic or copper, and a hammer of similar material. The hard part this way is ensuring the test piece isn't damaged or twisted!
How do I ensure the best outcome for my reverse bend test?
Ensure that your test piece is placed properly in the guides, and grips, and you bend the piece completely 90° in each direction, each interval per your testing requirements.
One direction completely bent and back to its original position is considered one bend.
Repeat in the opposite direction without interruption
