Even with a large selection of standard Criterion Tube Bender designs, it is sometimes necessary to design a "special" Tube Bending Machine in order to provide the optimum application solution.

Applications that may require a specially designed Tube Bender usually have one or more of the following characteristics:

• Very large radius
• Very high volume

• Unique material spring-back vs. part repeatability requirements
• Complex part design with multiple "design interference" zones
• Requirement for unique material handling of part in automatic machine

The following photos and related videos listed below show a few special Tube Bending Machines that provided practical solutions to our customers' applications.

In-Line Transfer Tube Benders

Criterion also provides in-line multiple station transfer Tube Benders that utilize either compression or draw bending heads. The type of control [CNC or non-CNC] utilized depends upon the application.
