The tooling

A clean edge — held by the tool

Cutting tooling separates the finished pack from the web. A hardened cutting edge shears the material against a matched die or anvil — and the tool holds the clearance, contour and depth constant, part after part.

Most cutting tools are one of two builds: a steel-rule die that crush-cuts against a hardened plate, or a matched punch and die that shears with a controlled clearance. Both are cut from your part CAD so the contour lands exactly on the formed feature.

How it works

Anatomy of a cutting tool

Four elements decide edge quality — and every one lives in the tool, which is why the tool matters more than any machine setting.

01 · CUTTING EDGE
Hardened cutting edge

The profiled edge that shears the part contour — hardened and ground to match your outline exactly.

02 · DIE / ANVIL
Matched die or anvil

The edge shears against a matched die opening or hardened anvil plate — it backs the cut and sets the shear.

03 · CLEARANCE
Controlled clearance

The gap between punch and die — typically a few percent of gauge. Too much burrs; too little wears the edge.

04 · STRIPPING
Stripper & ejection

Strips the skeleton web off the edge and ejects the part — or leaves small nicks so parts stay in the web.

Cut types

Three ways to cut, one tool programme

Which cut you need depends on the pack — how clean the edge, how high the volume, and whether parts stay in the web. Pick one to see where it fits.

Steel-rule die

A steel cutting rule is bent to your contour and set in a base, crush-cutting the material against a hardened plate. Fast and economical to make — the quickest route to a first cut and to lower volumes.

Rules of thumb for cutting tooling

Cut geometry
Cutting clearance~5–10% of gauge
Corner radiiR4 typical — sharp corners tear the cut
Registration to formGuided — the contour must track the formed feature
Min. web / matrix widthKeep enough skeleton to strip cleanly
Edge & retention
Burr sideControlled to the scrap side — clean face on the part
Nick size / spacing~0.3–0.8 mm typical
Edge finishBurr-free for medical — no loose particulates
Force & wear

Edge hardening / coatingHardened tool steel — coated for abrasive films
Cut / seal in oneA cutting edge can integrate with a seal face — ask about combined

Prove the cut, then harden it

We prove the contour and clearance on a fast steel-rule or laser-cut die, then build the hardened production tool from the same CAD — matched punch-and-die, coatings and quick-change mounting for the line.

Materials

Cut edge, material and contour are matched

A clean cut depends on the material and gauge you run. Tell us the material and contour and we set the clearance and edge — and the forming tool for the tray follows the same programme.

Rigid
PETG & APET trays

Clear rigid trays and blisters — the workhorse of thermoformed packs.

Mono & laminate
Mono-materials & laminates

Recyclable mono-films and barrier laminates — cut clean without delamination.

Board

Card backers and inserts — die-cut to match the pack.

FAQ

Cutting tooling FAQ

Steel-rule die or matched punch & die — which do I need?+

A steel-rule die is faster and cheaper to make and crush-cuts against a hardened plate — ideal for prototypes and lower volumes. A matched punch and die shears with a controlled clearance for the cleanest, most repeatable edge and the longest life — the choice for high-volume and tight-tolerance medical packs.

What is cutting clearance and why does it matter?+

Clearance is the gap between punch and die, usually a few percent of the material gauge. Too much clearance leaves a burr and a rough edge; too little accelerates edge wear and can cause a ragged shear. The right clearance for your material and gauge is what gives a clean, repeatable cut.

Why do my parts have burrs or rough edges?+

Burrs come from too much clearance, a dull or chipped edge, or a cut running into a sharp corner. We set the clearance to the material, harden and grind the edge, and use generous corner radii so the cut stays clean over the life of the tool.

Can you leave the parts nicked in the web?+

Yes — small uncut bridges (nicks) hold the cut parts in the skeleton web so they stay registered for downstream handling and destacking, then push out cleanly. We size and place the nicks for your automation.

Do you make combined form-cut or seal-cut tools?+

Yes — a cutting edge can be built into a forming or sealing tool to form-and-cut or seal-and-cut in one stroke, and can combine into a single combined tool. It’s the same tooling programme.
