"We purchased our Ercolina Top Bender back in the early 90's and when it came time to upgrade we didn't think twice about buying a new Ercolina Mega Bender. I could never imagine going back to using elbows, with all the welding, grinding and labor involved."
Bob Cavanagh, Mid Island Steel
"The machines are a very solid product. We used the first bender so much we got another one a couple years later and use them both daily. The roller we have works very well for us on many jobs and is used every few months as the specific jobs dictate. It is nice to know that we have dependable machines to get the jobs out the door in a timely manner. Production time has reduced and that helps the bottom line.

Reasonable price, would buy again, thanks Dave."

Bending Methods
 |
Ram Style Bending: Material angles form as center axis advances toward two fixed outer points |
 |
Mandrel Bending: Materials supported internally and externally while being drawn thru counterbending die onto fixed radii tooling |
 |
Rotary Draw Bending: Material drawn through stationary counterbending die onto fixed radii former tooling to desired bend angle |
 |
Ring Roll Bending: Material formed using lateral movement and center roll downfeed pressure to achieve desired angles |
