Metawell® processing and design tips

Product catalog summary
Edge Forms
Metawell panels offer various edge designs that enhance stiffness, reduce injury risk, and simplify assembly. Designs like KR-90 and KR-120 are suitable for ceiling elements and can be processed with CNC workstations. Consider optical requirements, construction conditions, and environmental factors for border finishes. Techniques like postforming and edge-banding are used for interior constructions.
Riveting
Metawell panels can be connected using conventional rivets, with options for concealed riveting. Blind rivets and nuts are recommended for maintaining visual aesthetics. Suppliers include Titgemeyer, Boellhoff, and Gesipa.
Sawing
Metawell panels can be cut using circular, jig, and band saws. Ideal saw blades have flat trapezoidal teeth with negative tooth positions. Vertical saws are recommended for large panels. Suppliers include Leitz GmbH.
Milling and Drilling
Wood-working tools are ideal for processing Metawell panels. Milling contours and grooves require specific tools like CNC routers and prismatic cutters. Suppliers include Hoffmann GmbH and Leitz GmbH.
Bonding
Bonding is preferred for Metawell panels due to uniform stress distribution and vibration dampening. Adhesives prevent contact corrosion and are available from suppliers like Sika and 3M.
Forming
Metawell panels can be plastically shaped, with bending easier perpendicular to corrugation tops. Trials are recommended to determine appropriate parameters and manage inherent tensions.
Overview
The document provides detailed technical specifications and guidelines for the use of Metawell® Aluflex panels, focusing on their flexibility, forming techniques, painting, and coating options.
Specifications
Metawell® Aluflex panels are designed to be flexible in one direction and rigid in the other, making them ideal for formed structures. They can be easily transformed around the axis parallel to the corrugation tops with small bending radii.
Forming Techniques
  • Parallel to Corrugation: Allows for easy transformation with smaller bending radii. Over-bending is crucial to compensate for material spring-back.
  • Perpendicular to Corrugation: Increases stiffness, suitable for direct mounting. Smaller radii may cause the corrugation to flatten.
Painting
Metawell® panels are suitable for high-demand visual surfaces. Key considerations include:
  • Maximum exposure temperature of 100°C.
  • Minimum cover sheet thickness of 0.8 mm for an even surface.
  • Three painting techniques: Coil-Coating, Powder-Coating, and Spray Painting.
Spray painting involves specific steps, including surface preparation and application of a coating varnish.
Coating Options
Metawell® panels can be coated with various materials, considering temperature limits and expansion coefficients. Options include:
  • Filler and plaster coatings for improved adhesion and reduced cracking risk.
  • Foil coatings using laminating techniques.
  • High-pressure laminates requiring careful glue selection.
Consultation is recommended for other materials like wood or glass.
Recommendations
Trials with samples are advised to determine working parameters, and adherence to manufacturer instructions is crucial for successful application.

Ed g e f orms Edge designs Metawell® offers other possibilities for edge finishes than sheet metal, which is due to its specific panel structure. More significant characteristics can be created at the edge of a sandwich panel by use of an application-matching edge design: • optical adjustment of the edge to the application • increase of the element‘s stiffness in the edge areas • reduction of the risk of injuries caused by sharp metal edges • reduction of assembly work by „automatic“ fitting e.g. by integrated drill holes for connectors • concealed attachment of profiles and fittings at the back...

Border finishes Plastic beading Edge profile Glued insert Besides foldings many other border finishes are possible with Metawell® panels. When choosing an appropriate finish the following aspects should be considered: • Optical requirements (design, type of surface) • General constructional conditions (flush connection to the panel surface, fixing of accessories or connection with other elements) • Ambiant parameters (temperature, pressure, affecting media) • Load on the borders during operation (mechanic stress, thermal loads, type of element – mobile or fixed mounting) • Requirements with regard...

Specifications Tool parameters Source of supply Modifications and errors reserved Meta well metal sandwich technology Metawell® can be worked with circular, jig and band saws with conventional saw blades: dihedral saw blades should not be used, however, since the teeth may become entangled between the cover sheet and the corrugation producing an unclean cut. Flat trapezoidal teeth with a negative tooth position and hard metal cutting edges have proven ideal when using circular saws. A format-cutting sliding table or the use of vertical saws is advantageous when processing large panels. For optimum...

metal sandwich technology MILLING AND DRILLING Specifications Metawell® panels can be processed with hand tools and machine tools. Wood-working tools are ideal, especially if equipped with the relevant protection device against metal cuttings, since processing Metawell® is more closely related to processing wood than to processing metal. This refers particularly in terms of the large surface area, the clamping techniques, the feed speed and the lack of requirement for coolants and lubricants. In addition, the usability of the existing suction device must be checked in advance. In addition, the...

Metawell® processing and design tips-11

Metawell® panels, as e.g. the panel type Alu CC 08-02-05 / H6 which is frequently used in interior constructions, can be plastically shaped around one axis with appropriate devices. The forming process creates tensile strain in one cover sheet of the panel and crushing strain in the opposite cover sheet. The loading direction has also an influence on the panel, which is due to the fact that the core of Metawell® panels is a corrugated sheet: • When bending parallel to the corrugation tops, the cover sheet which is under crushing strain may buckle between the corrugation peak. Therefore only large...

Metawell® Aluflex Fig. 1: Transformation parallel to the corrugation tops Metawell® Aluflex consists of a thin corrugated aluminium sheet that is glued to one flat cover sheet. This makes for a panel that is very flexible in one direction but rigid in the other, which is ideal for formed structures. Forming parallel to the corrugation Thanks to its special structure Metawell® Aluflex can be very easily transformed around the axis parallel to the corrugation tops, with smaller bending radii (e.g. for Metawell® Aluflex 05-02 / H4.7 smaller than 200 mm) even plastically (see fig. 1). The bending...

I n d i vidual col ouring Painting Thanks to their even surfaces Metawell® panels are particularly suited as design material for surfaces that have to meet high demands regarding their visual effect. With the multiple possibilities there are some important aspects which have to be considered: • The maximum temperature the panels can be exposed to is 100° C. Higher working temperatures might be tolerable for special paint procedures, but must be verified by the plant. • To receive an optically even surface the minimum thickness of the cover sheet (visible side) should not be less than 0.8 mm....

Because of its flat surface Metawell® panels are an ideal substrate for a variety of coatings. However, basic aspects have to be considered: • The maximum temperature the panels can be exposed to is 100° C. Higher working temperatures may be possible on request. • When selecting a coating the different expansion coefficients of panels and coating material must be taken into account. Preliminary tests should always be carried out to check the suitability of the selected combined system. Filler and plaster coatings In principle, any fillers suitable for metal substrates, such as those used in the...
