Sandwich / Crush Core / Honeycomb Hot Presses

Langzauner produces and develops tailor-made press systems for sandwich, crush core and honeycomb hot presses in various sizes and configuration levels. All systems are tailored exactly to the needs of the customers.

Crush Core „Advanced Material for Aircraft interiors“ for the production of very lightweight, high-strength composite molded parts made of glass-fiber reinforced plastics (GRP) and “Crushed Core” honeycomb profiles. “Crush core”, thermoset prepregs, honeycomb cores, engineering thermoplastics and honeycomb are used by most aircraft manufacturers. Airbus and Boing in particular, and the largest Tier I interior suppliers, specifically use “Crush Core” materials. The application examples are very diverse: floor panels, ceiling panels, window surrounds, flat panels, luggage rack, hatrack door, cabin modules, cargo panels, side walls, toilet modules, door frame trim, …

FAQ

Flexible software records relevant process data such as pressures, temperatures, and times and stores them. This creates complete traceability: for every component, it is later possible to trace the conditions under which it was manufactured, an important point especially in the aviation industry.

First, core material and cover layers are positioned in the tool. The press then closes, the tools are brought to the correct temperature, and defined pressure is applied. This causes resins and adhesives to flow and the composite to cure. After the cooling phase, the finished panel is demolded.

Whenever large surfaces need to be lightweight yet stable, especially in aviation. But sandwich and honeycomb structures are also an interesting solution wherever weight, stiffness, and fire protection play a role.

These are composite components with a lightweight core and cover layers, similar to a “waffle” or “honeycomb” principle. A lightweight core (e.g., honeycomb or foam) is pressed between two cover layers. The result is very lightweight, yet still stiff and load-bearing panels.

Depending on requirements, storage and retrieval machines, storage technology, handling systems, and robot and gripper technology can be integrated. These take over loading and unloading, positioning sensitive cores and panels, or transport between individual process steps, up to a fully automatic production line.
