Circle punching

During Punching of double-sided adhesive foils, the two-sided adhesive film materials on both sides are contour-cut into precisely defined shapes—matched exactly to the component geometry and the assembly process.

This solution is particularly advantageous when:

• two substrates are to be permanently joined
• precise fits in the serial production process are required
• thin, nearly invisible adhesive bonds are desired
• assembly times should be reduced and processes automated

Punched adhesive foils enable a clean, reproducible, and assembly-ready solution.

Almost all market-standard double-sided systems can be processed, e.g.,:

• Double-sided transfer adhesive films (without carrier)
• Carrier-based adhesive films (e.g., PET carrier)
• Thin high-performance films for permanent bonding
• Foam-based double-sided systems
• Custom-laminated multilayer composites

Additionally, adjustments such as adhesive formulation changes, one- or two-sided modifications, or the replacement of the protective cover (paper or film liner) are possible.

The achievable precision depends on the material structure and the overall thickness.

Through modern punching technology as well as optical quality control, tight dimensional tolerances and high repeatability are possible – even for intricate contours, internal cutouts, or functional openings.

Depending on the application process, a range of finishing options is available:

• Loose individual parts
• On rolls (for automatic feeding)
• On sheets
• With finger lift or peel-off aid
• With defined non-adhesive areas
• With modified protective cover
• As an installation-ready, multi-layer composite solution

The configuration is tailored precisely to the intended assembly process – manual, semi-automatic, or fully automatic.

Cost efficiency is determined, among other factors, by:

• Film type and total thickness
• Type of adhesive (e.g., for low-energy substrates)
• Contour complexity
• Tooling effort
• Quantity
• Additional processes such as laminating, liner changes, or application aids

Modular manufacturing processes enable both prototypes and production runs to be produced cost-effectively.

To enable accurate costing, the following information is helpful:

• Technical drawing or die-cut contour
• Material specification or substrate details
• Overall thickness and the desired adhesive type
• Requirements for temperature, UV, or chemical resistance
• Desired delivery form
• Project or annual quantity
• Information about the application process

The more precise the information, the more efficiently the optimal adhesive solution can be developed.

Samples and pre-series can be produced on short notice.

Thanks to flexible stamping and converting processes, rapid test samples are possible – ideal for validations, pilot runs, or process optimizations.

Ja, runde Stanzteile können als Rollenware oder Bogenware ausgeführt werden. Selbstklebende Kreise werden häufig auf silikonisierter Trägerunterlage geliefert, damit sie sauber entnommen, gespendet oder weiterverarbeitet werden können. Auch ein- und mehrbahnige Anordnungen sind möglich.

Bei einer einbahnigen Anordnung liegen die Kreise hintereinander in einer Reihe auf dem Träger. Bei einer mehrbahnigen Ausführung werden mehrere Reihen nebeneinander angeordnet. Das erhöht den Output und kann besonders bei kleineren Durchmessern oder hohen Stückzahlen wirtschaftlich sinnvoll sein.

Für eine Anfrage sind Durchmesser, Material, Materialdicke, gewünschte Stückzahl, Lieferform, Anordnung, Toleranz und Einsatzfunktion hilfreich. Bei Ringen oder Sonderformen sollten zusätzlich Innen- und Außendurchmesser, Stegbreite, Zeichnung oder Skizze sowie Angaben zur Entnahme oder Weiterverarbeitung angegeben werden.
