- Standard dimensional tolerance of +/-.005” for some materials - Tolerances are mostly material dependent. For example, a thin stable film will have a much tighter tolerance than a thick soft foam. Rotary tooling is machined generally to +/- .004” on the tool after heat treat, Steel rule dies are typically made to +/- .010” and chem-etch/wire EDM hard tools are +/- .002.
- Intricate shapes – regardless of shape design we can have tooling made to produce the shape required – this sometimes requires multiple dies to be made performing 1st, 2nd and 3rd registered cutting when all the cutting blades cannot fit onto just one die.
- High speed cutting – Rotary diecutting allows us to produce parts over 10 times the speed of flat bed steel rule diecutting methods. Web feed speeds up to 300 FPM (feet per minute) can be achieved on some materials/parts.
- Roll to roll or roll to loose pieces available – Depth of blade cut will determine if a loose pcs are produced (called diecutting where the blade cuts all the way thru all substrates) – or – parts on a roll (called kisscutting where the blades cut thru the top layers but not the bottom liner). Note: Tooling can be made to do both. For example; a ring shape can have the OD kisscut and left on a roll and the ID diecut and removed)
- Ideal for high volume – High speed rotary tooling allows high volume cutting due to speed of web feed with relative little set up time.
- Multiple unwind and rewind stations – Standard machines have been modified allowing extra unwind and rewind of input, waste and finished rolls for demanding applications of multiple web processing.
- Webs up to 18" wide possible – Our latest addition is a state of the art Aztech rotary press that feeds up to 18”wd input stock with 3 diecutting stations all servo controlled for fine tune adjustment of parts size or part location on the web.
- Island placement and removal of adhesives – Selectively placing a precut substrate onto a web (roll) in an organized pattern often subject to secondary cutting. (Think band-aid where there is an island of cotton placed in the center of adhesive bandage with release liner and cut to size). We can also selectively remove parts from a web using either air ejection or vacuum parts built into tooling that separate the waste slug from the roll.
- Vacuum removal of slugs – Vacuum inserts built into tooling will pull slug waste via vacuum from a cut part during the cutting process eliminating manual de-slugging and reduced part cost.
- Air eject removal of slugs – Directed air flow thru a tool using pressurized air thru a probe will also remove slug waste from a part during the cutting process
