From sandwich panel to finished component: cnc machining, assembly, finishing and decorative surfaces
Mechanical processing and surface finishing extend the application potential of sandwich panels, transforming a semi-finished product into a component ready for assembly or installation.
CNC machining, fastening systems, edge finishing and surface treatments are developed to meet specific project requirements, helping optimise manufacturing processes, reduce downstream operations and simplify integration into the final product.
CNC machining and customisation
CNC machining enables the production of customised sandwich panels and components, adapting geometries, machining operations and integrated features to meet specific project requirements.
Precision cutting
Precision cutting according to technical drawings and dimensional specifications.
Shaping
Production of simple or complex geometries and custom profiles.
Milling
Creation of seats, grooves, pockets, preparation of box structures and other functional processing
Drilling
Through and blind holes, with preparation for inserts and rivets.
Engraving
Custom logos, markings and engraved details.
Engraving
Bespoke machining operations and the development of application-specific solutions.
Decorative and structural edge finishing
Edge finishing protects the panel core and provides a clean, durable finish. Depending on the configuration, it can serve a primarily aesthetic purpose or accommodate fastening systems and local structural reinforcements.
Available solutions include:
- Applied edge finishing in aluminium, MDF, PVC, ABS, solid wood and laminates
- Aluminium C- and T-profiles
- Folded metal edge finishing
Flat strip edging
BT-profile edging
C-profile edging
Edging by folding the outer edge of the skin/facing
Fastening and joining systems
Sandwich panels can be prepared for attachment to supporting structures or for joining adjacent panels. Inserts, fastening systems and joining profiles are integrated according to the installation method and the specific requirements of the final application.
Available solutions include:
- Through-fastening systems and self-tapping screws
- Bolts
- Visible or concealed rivets
- Threaded inserts
- Façade anchoring systems
- Joining profiles
- Custom solutions
Surfaces: Finishes and surface coverings
Aesthetics and protection, without compromising on structure
Sandwich panels can be customised with metal finishes, decorative surface coverings and protective treatments. Each solution is selected according to the panel configuration, service conditions and performance requirements of the final application.
Metal finishes
Metal surfaces can be customised with a wide range of finishes, from industrial coatings to decorative effects, meeting specific aesthetic and design requirements.
Available solutions include:
Decorative surface coverings
Sandwich panels can be faced with a wide range of decorative materials, combining the structural performance of sandwich technology with specific aesthetic requirements.
Available solutions include:
Protective surface treatments
Surface treatments prepare and protect the panel surface, improving corrosion resistance and enhancing suitability for subsequent processes such as bonding or painting.
Available treatments include:
