ALSET™ is a composite material that is a strong laminate of metal and resin film without the use of adhesives.
Customers can choose the combination that best suits their needs.

  • Resin films: PA, PP, UHMWPE, fluorinated, PET, etc. PC, PBT, PPS are under development.
  • Please feel free to contact us as we may be able to process metals and films not listed here.


Features & Benefits


  1. (1)Since the film is laminated to the metal, the post-process of applying the film for insulation, metal protection, etc. becomes unnecessary.
  2. (2)Since the film is laminated to the metal, it is possible to apply printing that cannot be applied directly to the metal.
  3. (3)For heat-welding applications, dissimilar metals and resins can be joined in the mold by selecting a film that can be heat-welded to injection-molded pellets as the film layer of the ALSET.
    Since welding is performed by heat only, no prior treatment of the metal or resin is required.
  4. (4)Since no adhesive is used, there is no risk of cohesive failure at the adhesive layer, even when processed into complex shapes.

Actual Applications, Expected Applications


  1. (1)Deep drawing: Aluminum electrolytic capacitors, LiB housings, etc.
  2. (2)Insulation and heat dissipation: bus bars, power module components, power supplies, PC components, etc.
  3. (3)Thermal welding: automotive parts, power module parts, etc.

Thickness, Composition


Maximum width is 50 cm. Since the applicable thickness and width vary depending on the type of metal or resin film, please consult with us individually.
