The lamination industry is a specialized technical sector where equipment performance and reliability directly determine the quality of the finished product. This industrial technique requires tailor-made solutions to ensure adhesion, uniformity, and durability of the applied coatings.
Lamination consists of applying a thermoplastic decorative film to profiles, providing a wide variety of aesthetic finishes while preserving the structural properties of the base material.
The Industrial Lamination Process
Lamination is a sophisticated industrial process that transforms the appearance of profiles through the application of a decorative film. The process requires perfect control of several critical parameters to guarantee the quality of the final result.
Surface preparation is the first crucial step. Before applying the film, the surface of the PVC (or other) profile is carefully cleaned and prepared to ensure optimal adhesion. This stage directly conditions the quality of the final bond and the durability of the coating.
Lamination is carried out under controlled pressure and high temperature to ensure homogeneous and resistant adhesion. The adhesives used are adapted to the constraints: polyurethane (PU) for versatility, or high-temperature formulations for the most demanding applications.

Thermal and Mechanical Constraints
The lamination industry faces multiple technical challenges that require high-performance equipment. Application temperatures can reach 600°C in extreme conditions, while roller pressures vary between 2 and 8 bars depending on the application.
The main issues include:
- Thermal deformation of rollers under heat
- Premature wear of contact surfaces due to friction
- Vibrations generated by variable line speeds depending on the application
- Misalignments caused by differential expansions
Adhesion and Quality Issues
The most common defects in lamination processes often result from poor control of application parameters. Insufficient adhesion causes premature delamination, while thermal variations lead to dimensional distortions.
Roller wear generates surface irregularities that directly affect the visual quality of the finished product. Surface contamination also represents a constant challenge, especially in industrial environments where airborne particles can compromise the adhesion of the decorative film.
