KEIYO BEND CO., LTD.

We lead the world in automation systems centering on pipe benders!

We manufacture pipe benders (pipe bending machines). Specifically, we develop, design, manufacture, and sell CNC pipe benders, CNC wire benders, various pipe-end bending machines, various specialized machines, and automation systems. We are known as a unique bender manufacturer with original technologies (patented in Japan and abroad) and extensive expertise in automation systems and multiple-process pipe benders that incorporate pipe bending processing with multiple other processes that precede and follow it.

Product description
[CNC pipe bender]
Combining the right/left bending mechanism with the mechanism that rotates materials enables bending of pipes in multiple directions. Forming complex compound R shapes (a series of curves) usually requires multiple processes when conventional press working or other manufacturers' benders are used. Our CNC pipe bender can accomplish this with just a single process.

[CNC wire bender]
Continuous processing is enabled by straightening wire that has been wound into a coil, then 3D bending, then automatic cutting. These operations take advantage of our original right/left bending technique, securing a wide working space and bending materials without damage.

[CNC straightening system]
Conventional straightening machines are manufactured for separate processes. Our CNC straightening machine has been re-engineered to function as a system. Of course, it provides full-closed control that utilizes an external encoder, enabling high-precision NC feeding.
Product concept
[Quality: High-precision bending]
(1) We have actively incorporated AC servomotors as drive sources, enabling numerical control in steps of 1/100 degree or 1/100 mm.
(2) Conventional hydraulics and air are replaced by AC servomotors, enabling a shift from modeled bending to controlled bending.
(3) Through in-house mold manufacturing, we have accumulated original know-how on molds that enables us to achieve high-quality bending.

[Operative: Flexible programs]
We provide programs that can be easily incorporated in preceding and following machines in an automated line. These programs feature increased operability, allowing users to create their own programs.

[Automation: Cost reduction]
Our core strength is in automation systems that combine automatic carry-in/carry-out machines (robots, specialized machines, etc.), specialized machines for preceding and following processes, and sensing technology. We give our customers a competitive edge by offering systems that withstand 24-hour use and also enable them to save labor costs.

[Maintenance: Easy maintenance]
We take into account the possibility of procuring parts on the user side from the design stage by using general-purpose parts that are widely distributed. Our NC programs and user-operated programs are designed to ensure easy management by enabling users to edit the programs by themselves.
