Combination Beading Expanders 2.0", 2.5" and 3.0"

Completing the tube rolling and beading in one operation.

Combination Beading Expander The Combination Beading Expander completes beading in one operation. This is a significant saving on time and manpower. Beading tubes have always been an arduous task for the operator. First the tube was rolled then beaded with a beading tooling in a chipping gun. Then finally the tube needed to be re-rolled to tighten up the seal. Health and safety for the operator has always been an issue here, the noise and vibration being the main concerns. As you can see it was a long and tedious operation to carryout and many times in confined spaces.

Now with the Combination Beading Expander tool, the whole operation is completed in one and with no health and safety issues for the operator. Each unit can roll and bead one OD size but with a change of the guide roll assembly and the beading roll, the unit can cover most common wall thicknesses of tube. Usually 10-13 BWG (0.134"-0.095").

Features of the Combination Beading Expander

  • Turns three operations into one by Rolling and Beading at the same time saving on labour costs, stress from health and safety on your employees and overall tooling costs.
