Process optimization

I - Fingerlift and Peel Tabs

Ideal for double-sided adhesive solutions, because the liner can be lifted cleanly without touching or contaminating the adhesive surface – reliable for manual assembly and also suitable for semi- and fully automatic processes.

II - Butterfly Closure | Patch Technique

The butterfly closure operates with two overlapping liners that function like wings. This allows the die-cut part to be temporarily fixed and precisely aligned before the protective cover is fully removed and the final bond is made.

III - Picking & Placing of Fingerlift Tabs

The goal is hundredth-millimeter precise, absolutely reproducible placement of the processing aids on the die-cut part – for example for a defined grip zone that must ensure perfect handling in the automated process.

IV - Perfect Positioning Through Robotic Technology

If the adhesive layer of the placed fingerlift tab bonds with the adhesive layer on the die-cut part, the bonding process cannot proceed — hence perfect positioning through Pick & Place.

I - Fixation & Positioning Aids

Fixation and positioning aids ensure that stamped parts sit correctly “as if by themselves” – e.g., along contours, edges, screws, cutouts, or reference points. This turns a rough estimate into a repeatable process.

II - Printing & Orientation Aids

A print makes adhesive solutions “self-explanatory”: for orientation, assignment, and traceability. Typical examples include batch numbers, assembly group numbers, position identifications, direction arrows, or assembly instructions.

III - Perforation<\/strong><\/p>

I - Fully automated processing

Seamless process integration means adhesive solutions do not run 'in the background' but support the line's cadence: fewer roll changes, lower line stoppages, and handling that no longer turns C-parts (e.g., adhesive tape/stamped parts) into a 'process bottleneck'.

II - Corona pretreatment

Corona pretreatment is an established method for surface activation: it increases surface energy, improves wettability, and thereby provides the basis for difficult-to-bond materials to become self-adhesive.

III - Liner change<\/strong><\/p>

An optimized liner (protective cover) is critical for fully automated processing: The liner must feed stably, peel cleanly, provide perfect peelability, and fit the system (unwinder\/dispenser, grippers, sensors).<\/p>

IV - Fully reproducible product solutions<\/strong><\/p>

Reproducibility is the key so that adhesive solutions in manufacturing do not become a source of uncertainty – but function reliably like a standardized component.<\/p>

V - Optical metrology with line camera<\/strong><\/p>

I - Remove the remaining grid

Excess punching material is removed directly in production. Result: No grid removal work at the customer.

II - Repositioning away from the die-cut edge

Flowable adhesives can cause punched parts to adhere to the die-cut edge. By offsetting the punched parts on the substrate, the parts remain easily detachable and reliably dispensable in the process.

III - Removal of inner punch-outs

Material residues from the inner punch-outs are removed as needed directly, so no additional work is required at the customer.

IV - Technical cleanliness

Production under cleanroom conditions: reduction of dust and dirt particles on the adhesive die-cut part, which could lead to rejects.
