sandwich panels
A sandwich panel is composed of two skins (or faces) stuck to a core. The assembly of these three elements form a unit of high rigidity and increased lightness compared to a homogeneous panel with the same mechanical properties.
- The skins can be metal sheets, plastic, laminate, wood or composite.
- The core is made either of aluminium, plastic, wood or cardboard honeycomb, or a solid plastic, composite or mineral core.
These panels are split into two large categories which we transform in our workshops.
Honeycomb structure sandwich panels
Type: Alucore® – Compocel® – Larcore® – Nidaplast®
Skins: aluminium, wood, reinforced polyester …
Honeycomb core: aluminium, Nomex®, polypropylene…
Sectors: transport (rail, shipbuilding industry, aeronautic), machines, etc.
Honeycomb panels are sandwich panels with a honeycomb core that combines lightness and high mechanical performance: technical floors, ceilings, doors, partitions, facades, machine outer body, etc.
- Aluminium honeycomb: this all-aluminium panel has a high resistance to bending, as well as remarkable flatness, for a low weight.
- Polypropylene honeycomb: an economic and reliable solution ; the honeycomb core is covered in a non-woven fabric which allows the adhesion of the glue during the process of bonding the polyester skins to the aluminium
- Aramid honeycomb (Nomex®): non-metallic product, very light weight, resistant and an excellent electrical insulator; the honeycomb core is made of a meta-aramid fibre paper impregnated with phenolic resin.
Solid core sandwich panels – composite panels
ype: Dibond® – Compocel® – Reynobond® – Alucobond® – Hylite®
Skin: aluminium, wood, plastic…
Core: plastic (compact or foam), mineral…
Sectors: display (display, point of sale), advertising panels, nautical/naval (furniture and partitions), industrial vehicles (cargo box), building/architecture (facade cladding), etc.
In this type, we find mainly aluminium composite panels (aluminium faces) which are renowned for their lightness, decorative and insulating qualities. They are also rigid, impact resistant and some have sound dampening qualities.
The sandwich panels with a foam core are excellent thermal insulators.
- DIBOND®– REYNOBOND® are sandwich panels consisting of two aluminium sheets with a polyethylene core. Lightweight, transformable in 3D, they are extremely stable and rigid. Interior and exterior applications, numerous colours and finishes possible. Specially designed for the display sector (displays, Point of Sale)
- ALUCOBOND® Plus and A2 are composite panels consisting of two sheets of aluminium with a mineral core. These panels are intended, distinctively, for architecture. Other external applications are possible.
- HYLITE®, the world’s thinnest composite panel (thickness 1.2mm and 2mm) has a special feature: its core can be used as a hinge.
- RENOZIST® is a true composite panel made of wood fibres and expanded polymers. It is lightweight, resistant and hydrophobic and rot-proof. It is also inexpensive.
CNC machining of honeycomb panels for industry
Honeycomb panels are a highly relevant technical solution for industrial projects requiring an excellent balance between light weight, rigidity and machining precision. With CNC machining, it is possible to manufacture custom honeycomb sandwich panels for demanding technical applications while taking into account dimensional, mechanical and aesthetic constraints.
Favre Technics supports manufacturers looking for CNC machining of aluminium honeycomb panels and sandwich materials for industry, technical furniture, interior fittings and lightweight structural applications. This approach makes it possible to produce custom technical parts, from prototypes to small and medium production runs.
A lightweight, high-rigidity solution for industrial applications
Honeycomb panels are often selected as a lightweight structural solution for industrial use. Their sandwich construction provides strong mechanical performance while significantly reducing overall weight. In many cases, they can be a relevant alternative to solid aluminium or heavier panel solutions when rigidity must be maintained without increasing the weight of the final assembly.
This technology is suitable for many industrial applications, including technical furniture, cladding panels, interior fittings, partitions, doors, floors, ceilings and other components requiring a lightweight yet rigid material.
Custom-made honeycomb sandwich panels
Favre Technics machines custom honeycomb sandwich panels according to the needs of industrial companies and professionals looking for parts manufactured to their own specifications. CNC machining makes it possible to work on different panel formats, achieve precise cutting and deliver functional parts ready to be integrated into technical or decorative assemblies.
This expertise can meet a wide range of requirements:
- honeycomb panel machining;
- aluminium honeycomb panel cutting;
- CNC machining of sandwich materials;
- custom-made honeycomb parts;
- small and medium production runs for industrial applications.
Each project is studied according to the skins, the core material, the final use of the part and the expected level of finish.
Industrial subcontracting for honeycomb panel machining
Favre Technics works with companies looking for a subcontractor able to machine honeycomb panels for industrial, technical or interior fitting applications. This service is especially relevant for manufacturers wishing to outsource CNC machining of sandwich panels, save time on the production of specific parts or rely on a specialised workshop for the machining of technical materials.
Our know-how fits into a custom industrial subcontracting approach focused on machining precision, technical consistency and adaptation to the requirements of each project.
Industrial applications of honeycomb panels
Honeycomb panels are used in many sectors because of their structural qualities. They are particularly relevant wherever the weight-to-rigidity ratio is a key criterion. They can be integrated into projects involving technical furniture, interior fitting, cladding, transport, partitions or the manufacture of lightweight custom-made parts.
Their versatility makes them a strong option for companies looking for industrial aluminium honeycomb panels, custom sandwich panels or lightweight high-rigidity materials for specific technical projects.
Industries using honeycomb panels
Marine, shipbuilding, rail and other lightweight technical applications
Honeycomb panels are used in many industries where low weight, rigidity and machining precision are key technical requirements. They are particularly relevant for the marine and shipbuilding sectors, where they can be used for interior fittings, partitions, cladding, floors, ceilings and doors, helping to reduce overall weight while maintaining structural performance.
The rail sector can also benefit from this type of sandwich panel for interior applications, technical furniture, coverings, partitions and other custom lightweight parts. More broadly, CNC-machined honeycomb panels can meet the needs of companies involved in transport, technical fit-out, industry and equipment manufacturing that are looking for a lightweight, high-rigidity solution tailored to specific technical constraints.
