How is the wood grain effect achieved? What are the main processes?

  • A: Two main mature processes:
  • Lamination/Film Laminating: A high-definition wood grain printed PVDF/PET/PMMA polymer film is laminated onto the aluminum sheet under high temperature and pressure. This offers realistic texture and excellent weatherability, making it the mainstream process.
  • Transfer/Printing: The wood grain pattern is transferred onto the primed aluminum sheet via heat transfer or digital printing, then coated with a protective layer. This method is lower cost, but the texture depth and weatherability are usually slightly inferior to laminated products.
