Dots/die-cuts

An adhesive dot or a single-sided die-cut is a pre-cut piece with a single sticky surface. It can take a round, square, rectangular, or more complex shape depending on the application. Ready to apply, it allows for protecting, masking, holding, or marking a specific area without having to manually cut adhesive tape.

Adhesive tape is supplied in the form of a continuous roll and generally needs to be cut to the desired length. A die-cut is already shaped according to defined forms and dimensions. This allows for obtaining regular pieces, reducing handling, and improving repeatability during series applications.

Single-sided adhesive dots can be used for masking before painting, saving functional areas, protecting surfaces, marking, or temporarily holding components. They are particularly suitable for repetitive operations requiring quick, precise, and identical application on a large number of pieces.

Yes, adhesive pieces can be designed in different shapes and dimensions according to the geometry of the area to be protected. This can include round dots, squares, washers, shapes with cut-outs, or technical die-cuts made from a plan. The feasibility depends on the adhesive material, dimensions, and requested tolerances.

The choice depends on the desired function, the application surface, and the conditions of use. It is particularly important to consider the temperature, the duration of application, the resistance to solvents or chemicals, the flexibility of the substrate, and the level of adhesion required. A test allows for checking the hold of the dot and the quality of its removal.

Yes. Some dots are made from technical adhesive tapes, such as polyester with silicone adhesive, to withstand powder coating, thermosetting, or thermal treatment operations. The maximum temperature, duration of exposure, and number of cycles must be compared to the characteristics of the chosen adhesive part.

The parts can be supplied on a liner to facilitate their storage, handling, and application. A grip tab can also be added to make it easier to grasp the dot and remove it after the operation. DERFI can study the shape, dimensions, adhesive support, and packaging suitable for the constraints of the workstation.
