  • Reduced Material Waste: The precise nature of roll forming minimizes material scrap, making it an environmentally friendly option.

Components of a C Z Purlin Roll Forming Machine:

  1. Uncoiler: This component holds and feeds the raw material coil into the machine.
  2. Feeding System: It guides the material into the roll forming unit accurately.
  3. Roll Forming Unit: This is the heart of the machine where the actual shaping of the purlins occurs.
  4. Punching System: It creates holes or slots as per design requirements.
  5. Cutting System: This cuts the formed purlins to the desired lengths.
  6. Control System: It governs the entire operation and settings of the machine.
  7. Stacker: The stacker neatly collects the finished purlins for further processing.

Working Principle of C Z Purlin Roll Forming Machine:

  1. Step 1: Material Loading: The process begins with feeding the coil into the uncoiler, which gradually unwinds the steel coil.
  2. Step 2: Material Guiding: The material is then guided through the feeding system to ensure proper alignment.
  3. Step 3: Roll Forming: The roll forming unit shapes the material into the desired C or Z purlin profile.
  4. Step 4: Punching and Cutting: Holes or slots are punched as needed, and the purlins are cut to the required lengths.
  5. Step 5: Stacking: The stacker collects and arranges the finished purlins for easy handling and transportation.
