When we use progressive die in metal stamping manufacturing, a metal coil sheet or steel plate will be used. As we know, if the material is steel plate, we will adopt a transfer arm to realize automation feeding. But if the material is a metal coil sheet, how do choose the coil handling and feeding systems?
2-IN-1 uncoiler & coil straightener and servo feeder machine are the most popular choice by customers. This coil handling and feeding system are economical and durable with convenient operation methods.
Below is our GL coil straightener and uncoiler will be delivered to Portugal this week. This type of 2-in-1 uncoiler & coil straightener is suitable for 0.3-3.2mm thickness metal coil feeding in a progressive stamping line.


We could find that they are all equipped with pressing arms to avoid coil disperse when coil thickness is up to 2mm. Uncoiler mandrel is expanded by manual. The ID expansion range is +/-25mm. And there are 4 pcs of “A” frame to fix the coil.
Except these coil straightener and uncoiler machines, there are also servo feeders delivered together to Portugal.


Servo feeder always is equipped with a 2-in-1 uncoiler & coil straightener to build an automation metal progressive stamping line. The servo feeder is driven by a servo motor and drive, which can help to increase feeding accuracy. And they are easily operated due to there being a PLC program for feeding data settings. To connect the signal wire with the press machine, it will realize synchronization between the servo feeder and the press machine.
For these servo feeders, which will be delivered to Portugal, the PLC program is customized in Portuguese. So there are three languages that can be switched as wished.
Welcome to sending us your inquiry, we are glad to customize the coil handling solution as required.
