When sourcing a corrugated feeder, you must prioritize feeding speed (sheets per hour) and sheet size compatibility. Ensure the machine supports the specific flute types (A, B, C, E, F, or double-wall) used in your production. Look for features like lead-edge feeding systems for high-speed stability and vacuum suction mechanisms that prevent sheet slippage. Additionally, verify the positioning accuracy (typically ±0.5mm) to ensure seamless integration with downstream printing or die-cutting units.
