What is a decoiler machine?

A decoiler machine is an industrial device that holds, supports, and continuously unwinds metal coils for feeding into stamping, roll forming, or cut-to-length equipment.

industrial metal coil manufacturing

How it works

  • Coil loading: The metal coil is placed onto an expandable mandrel
  • Mandrel expansion: The mandrel expands to grip the coil ID securely
  • Controlled unwinding: AC motor rotates the mandrel with loop control
  • Downstream integration: Material passes through straighteners into the press

Hand crank, up to 2 tons, for electronics stamping

Motorized decoiler

Motor-driven, 2-5 tons, for medium production

Hydraulic decoiler

Hydraulic expansion, 5-20+ tons, for automotive
