Double Head Decoiler MTD-200 to MTD-400 | Yiming, Dongguan, China

Yiming's Double Head Decoiler (MTD Series) holds and pays off steel coil for high-speed precision stamping lines, such as motor stator and rotor lamination production. It is offered in three models, MTD-200, MTD-300 and MTD-400, for coil widths of 200, 300 and 400 mm.

Its two-mandrel design lets the operator load a fresh coil on one head while the other is feeding the line. This cuts the time lost to coil changes and helps raise output. It is normally installed ahead of a straightener, a gear feeder and a high-speed press.

Key Features

• Two-mandrel structure allows a new coil to be loaded while the other is in use
• Built from three parts: frame, spindle case body and load rack
• Spindle box on a long wheelbase support gives a compact footprint with large loading capacity
• Motorised and non-motorised versions available, and it can work with a straightener
• Spindle tiles made from A3 material, blanked, milled to angle, bent, drilled and milled
• Non-slip nuts on all fixing points to stop them working loose in operation
• Finely machined spindle screw and screw sleeve for smooth adjustment of inner and outer diameter
• Coil expansion by manual or hydraulic means
