Take a journey in, above and around our production shop and office with this high resolution virtual and aerial tour of Albina Co, Inc. See our state of the art roll bending machines in action from a plan view, soar through our bays, watch our certified welders in action, and take a peek into our office and newly renovated lunch and conference rooms.
Rotary draw bending is a cold bending method where the member is clamped to a rotating bend die and drawn around the bend die. The tailing tangent is held against the bend die by a pressure die, and the bend die rotates until the desired geometry is formed. A mandrel is often placed inside the member to restrain cross-sectional distortion during the bending process. Bends can also be formed with special draw-bending equipment where deformations are controlled by tensioning along the member axis. Rotary draw bending is commonly used to form small radius bends in smaller-size round, square and rectangular HSS members. Specific tooling is required for each member size, shape and bend radius; therefore, this method is best suited for projects requiring many identical bends. This bending method is primarily used in the machine and parts industry (Weisenberger, 2016) and for piping (Riviezzi,1984). The maximum degree of bend is 180°, but the minimum bend radii of round HSS is approximately 50% smaller than that of other cold-bending methods (Riviezzi, 1984). Have a need for consistent, accurate, and repeatable bent steel parts, hit us up today! We are standing by ready to assist!
We recently bent 215 pieces of .79” OD X .083” WALL C-276 for a chemical processing application. C-276 alloy is one of the most corrosion resistant alloys currently available. This project is a perfect example of how consistent, accurate and reliable we are with jobs that require extreme precision!

Tooling for 6" Coast Wallace Rotary Draw Bending Machine[/caption] The Pines #6 is a long machine with a customized back boost. This machine has the capacity to bend up to 6” pipe (and has the ability to bend thin wall material). In addition to round materials, this machine has the capacity to mandrel bend square and rectangular tubing, in fact it is currently under power to bend TS 12” x 4” x 5/16” wall the easy way to a 24” CLR. We plan to fully tool these pieces of equipment allowing us to offer countless new radii options for our customers growing needs. The recent changes have greatly improved moral in our shop, increased our efficiencies, and decreased lead times in certain areas of the shop.
