Metal Laminations

Metal Laminations

Photofabrication supply stacked and bonded metal laminations to high accuracy and consistency.

The use of a specialised resist provides both insulating properties within the stack as well as bonding capabilities. The etching process provides a burr free finish, ideal to eliminate problems during winding. The full process is available, including post stacking services such as grinding where required.


  • High accuracy and consistency
  • Low cost tooling
  • Various apertures, shapes and bar combinations
  • Variable bar heights
  • Various surface finishes available
  • Variable stack heights
  • Coating with Insulation properties
  • Surface Grinding option

For bespoke metal laminations the manufacturing technique of choice is Chemical Milling, let us illustrate this in more detail:

Main Benefits of Chemical Milling :

  • Low cost tooling
  • High accuracy
  • Customised parts – you design it – we make it! (Guidelines available)
  • Various apertures, shapes and bar combinations
  • Variable bar heights
  • Over 47 years experience in Photo etching metal laminations
  • Burr free & Stress free manufacturing method
  • Prototypes – fast turnaround to meet your needs
  • High volume capabilities
  • Various surface finishes available

Metal Laminations:

  • Photofabrication have over 47 years experience in the production of electrical steel laminations for high speed and ultra high speed motors.
  • We can manufacture to your specification from a range of high silicon, ferrite core materials.
  • We can advise on metal type / thickness etc.
  • We can produce and bond stacks of laminations (both ‘E’ and ‘I’ profiles) the stack height is completely customizable which incorporates top and bottom resist layers which also acts as an insulated coating and a good bonding agent. The liquid photosensitive resist that we use on most laminations is the ideal solution for the above.
  • Photofabrication lamination standards for all applicable mechanical and physical characteristics meet or exceed the recognized industry standards.
  • A layer of rust inhibiting paper (V.C.I. or equivalent) shall be packed between lamination layers.

Photofabrication laminations are made from various grades of electrical steels, silicon steels, nickel-iron alloys, and cold rolled motor lamination steel. To find out more about the metals available click here.
