Lamination

The technical bonding of multiple layers.

Lamination is the technical bonding process of multiple layers of identical or different materials.

There are different lamination possibilities: from roll to roll, from pre-cut to pre-cut (e. g. leather onto foam) and pre-cut to pre-coated carriers made of plastics or metal (3D).

C. H. Müller has a world-wide unique complete machine park, allowing to offer laminations in the following technologies:

OUR TECHNOLOGIES

  • Melt-print lamination with engraved rollers and thermoplastic hotmelts
  • Flat-bed / calender lamination with thermoplastic powders, adhesive webs or adhesive films
  • Flame lamination
  • Adhesive-free lamination with ultrasonic welding

Flat-bed / calender lamination with thermoplastic powders, adhesive webs or adhesive films

In this type of lamination, the adhesive media are positioned between the materials and activated by means of contact heat in a heating channel. This technology is particularly suited to substrates which are susceptible to bending, and for individual parts. Highest flexibility in the selection of adhesives offers a myriad of combination and design possibilities for the technical characteristics of the compound materials.

Melt-print lamination with engraved rollers and thermoplastic hotmelts

In this technology, the adhesives are molten in the extruder in granulate form, and applied as dots onto the back side of a substrate by means of the engraved roller. The results of the lamination or coating with respect to elongation, separating force, and other technical characteristics can be adapted by varying the adhesives and the engraving geometry.

Flame lamination

In flame lamination, the compound material is made of two or three substrates utilizing the adhesive characteristics of PUR foams on the basis of ether or ester, being flamed on one side or on both sides by means of line gas burners. The molten mass generated serves as adhesive medium. The lamination width in this process is up to 2100 mm.

C. H. Müller is the first lamination company in Europe which arranged a fully biological waste gas purification facility in line behind the flame lamination process. Environmentally harmful components of the waste gases are washed out and decomposed by microorganisms, leaving virtually no residues. Thus, only water vapour is exhausted to the atmosphere.
