Method For Assembling An Anti-Adhesive Film Onto A Metal Substrate By Hot Stamping

A method for manufacturing a coated cooking element comprising the following steps:

• i. Providing a metal substrate and a metal mesh, said metal substrate having a face intended to be brought into contact with said metal mesh;
• ii. Attaching said metal mesh to said face of said metal substrate;
• iii. Providing a film, said film comprising a layer comprising one or more semi-crystalline or amorphous thermoplastic polymers, said layer being intended to be brought into contact with said face of said metal substrate and with said metal mesh;
• iv. Heating said metal substrate and said metal mesh;
• v. Positioning said film such that the layer is facing said face of said metal substrate and said metal mesh which were heated in step iv.;
• vi. Assembling said metal substrate and said metal mesh with said film by hot stamping, said metal substrate and said metal mesh being at a temperature higher than the lowest of the melting points of the semi-crystalline thermoplastic polymers and the glass transition temperatures (Tg) of the amorphous thermoplastic polymers of the layer at the time of assembly.
