There are a few restrictions to this process but follow these rules and all will be okay. -
Slot Sizes : The general rule is that the diameter of a hole or the width of a slot cannot be less than 0.1mm or metal thickness, whichever is greater.
Bar Widths : As with slot sizes it is normally the case that the width of a bar or space between holes should be at least metal thickness.
Corner Radii : The process will produce an internal radius of approximately 2/3 of metal thickness. External radii are generally much sharper and when required can be reduced to a sharp point.
Tolerances : A tolerance of +/- 10% of the metal thickness or 0.025mm, whichever is greater, is the standard achievable tolerance we would like to work to although tighter tolerances can be achieved if required please give us a call to discuss.
Whilst stages one to four are in production, tools which have been made by us before are cleaned and inspected to ensure they are fit for use. New jobs that have not been made by us before will require a graphic tool to be made at this point. The graphic tool will be drawn, laser plotted, inspected and then passed on to our print department at stage 4. For more information about the production of the graphic tool please select graphics from toolbar at the top or bottom of the page.
