Frame Roll Forming Machine Price Range

Roll forming is a metal fabricating process where sheet or coil stock metal is continuously bent and shaped with a series of rollers until the desired cross-sectional profile is obtained. Frame roll forming machines are used to create frame and structural components with complex long length profiles by progressive rolling, cutting and welding from metal coils.

Frame roll forming provides an efficient, economical and flexible way to manufacture metal framing with customized dimensions and geometries compared to other fabrication processes. This guide provides a detailed overview of various aspects of frame roll forming technology and machines.

Overview of Frame Roll Forming Machines

Roll forming machines progressively form metal sheet or coil stock into diverse longitudinally uniform customized cross-sections and long lengths using a series of passes through sequentially arranged roll stations.

Key attributes:

  • Highly customizable continuous production of long length metal framing from coils
  • Capability to form complex structural shapes with tight tolerances
  • Lower tooling costs compared to other processes like stamping or press braking
  • Minimal material waste
  • Consistent quality and mechanical properties along the length
  • High production rate for mass production applications

Frame roll forming involves specialized roll forming machines that can manufacture long structural sections from metal strips. Frame roll mills integrate very robust designs with features like servo roll adjustment, automatic material feeding, in-line welding and cutting systems specifically for high strength framing products.

Types of Frame Roll Forming Machines

There are two main types of frame roll forming mills:

Single Main Line Frame Roll Forming Machines

  • Designed for high volume production of one profile design
  • Limited flexibility – profile changes require roll change
  • Example structural sections: C, U, Z, top hat, door frame

Versatile Quick Change Frame Roll Mills

  • Enable fast profile changes with quick change cassette systems
  • Used for lower to medium production volumes with profile variations
  • Reduce roll change downtime from hours to minutes
  • Ideal for door/window frame builders, steel furniture etc.

Key Components of Frame Roll Forming Lines

A frame roll forming system comprises of diverse modular components for material handling, forming and downstream processes:

  • Decoiler or uncoiler – feeds raw material coil stock into the process
  • Servo feed roll system – provides accurate material positioning
  • Roll forming stands – progressively form the material through series of rolls
  • Punching unit – cutouts or notches for attachments
  • Shear and cutoff – cut profiles to required length
  • Welding machine – joins cut sections for long continuous frames
  • CNC bender – forms special end shapes if needed
  • Runout tables – accumulate and straighten finished products
  • Automatic stacker – neatly stacks finished pieces
