As a rule, stack height tolerances are determined by the thickness of the sheet used (+/- 1 the thickness of sheet). In order to maintain tighter tolerance ranges, these stacks can be finished at a later stage.
We manufacture cores using the following technologies
- Bonded stacks, using bonding varnish technology
- Welded stacks (laser or TIG welding)
- Interlock simulation
- Slice technology to manufacture twisted stacks with all types of outside contours and groove slope - every single sheet is unique
- Riveted stacks
- Screwed stacks
Some of the topics above are described more detailed under "Technology".
