Card-Lamination

• Main Characteristics for card lamination   ( 6 Beiträge )
• Lamination process   ( 11 Beiträge )
  During the lamination process, heat is supplied to the layers through the heating plates. Vacuum is useful for reducing possible air enclosures. The foils are heated under pressure and are welded. After completion of the welding process in all layers of the product pack, the pressure should be raised for cooling.

  	PVC	ABS	PET	PC
  Temperature [°C]	130-160	155	130-160	180-200
  Heating pressure [N/cm²]	50-200	150	50-200	200
  Cooling pressure [N/cm²]	200-400	300	200-400	400
  Heating time [min]	15-20	18-20	15-20	18-35

  By using additional adhesives between overlay/core and core/core, it is possible to reduce the heating time to almost half of the time used for welding without adhesive. Depending on the adhesive the pressure also may be changed to 2 times the value of standard welding.
