751 Cropping

Most simple tool we can product, in the fact that it is not really a tool at all more a way of making a part.

Simple insulators can be run on one of two croppers we have at Presspahn to quickly produce simple shapes in high volume.

Pitch is set using mechanical stops and material is cut to length, width is established by processing material before cropping.

When to Use

Cropping is used when the customer solution requires a large volume of cut rectangles and tolerance is not critical.  Longitudinal creases can also be added to some parts to allow for forming in the typical u shaped channels. i.e. motor slot insulation.

Advantages
  • No tooling costs
  • Fast setup
  • Fast Running
  • Great for simple parts
  • Can put simple creases in parts at the same time.
Disadvantages
  • Only suited to thin, roll based insulation i.e. Presspahn, Formex, Hostaphan
  • Needs to be slit first
  • Limitations of maximum size
  • Best tolerance +/- 1mm
  • Cannot have any cut outs or shapes must be a rectangle or square only
Cost
  • No tooling cost
  • Material costs can be low depending on product and width.
  • Batch Qty < 5000 – 1000 pieces per hour running speed
  • Batch Qty > 5000 < 10000 – 2000 pieces per hour running speed
Timescale

2-3 Working weeks,  subject to material availability.

No job is too big or too small, too simple or too complicated.
