RAS Flanging Machine 21.20 is a specialized electromotorized machine developed by RAS Reinhardt Maschinenbau GmbH for high-speed and high-precision forming of 90∘ flanges on rectangular, round, and, most importantly, curved (radius) blanks made from thin sheet metal. It is a key tool in the HVAC industry for preparing duct segments for joining using Pittsburgh seams or Snaplock seams.
Machine Table with Extended Support Surface: Provides support for the blank before and after the forming zone.
Forming Rollers: A set of large rollers capable of forming a 90∘ flange with a height of 6 to 15 mm.
Adjustable Stop: An adjustable limiter (stop) for the initial bend of the flange, which serves as support during material feeding.
Motor Drive: With electronic control of the feed speed.
Automatic Sheet Guiding System: Simplifies operation by helping the operator maintain a constant flange height (8 or 10 mm) to ensure high repeatability.
Snaplock Top Attachment (for Button Punch): An additional unit mounted on top that allows for the perforation and displacement of "cams" in a single pass to create the element for a Snaplock seam (Cam Standing Seam).
Stainless Steel Version: Special forming rollers and inserts for processing stainless steel without surface damage.
Spring Steel Insert: An insert in the working table that increases its resistance to wear (e.g., from rough plasma cuts).
Foot Switch: For more convenient control of the processing cycle, especially when working with large parts.
