Most of these machines run on 3 phase power, and are heavy enough to require rigging for installation in a building. Common mandrel tooling is very expensive (one die/mandrel/wiper can easily cost over $5k on 3″+ machines). We have seen 3″ machines from other manufacturers starting at $90K and 4″ machines at $112K. The next nearest-priced mandrel bender with real (metal) mandrels is $60K without tooling (dies, clamp, mandrel, etc). Our mandrel bender can go up to 2.0″ OD and starts at roughly $2.5K with one full set of tooling for one size. Most mandrel benders are also fitted with electric/hydraulic power systems and automation or programmable features. Mandrel benders can also have wiper dies, which prevent the ripple that forms at the beginning of a bend on thin walled tubing.
