Cold Glue Multi-functional Laminating Machine
◆ It is used to wrapping PVC decorative film on the surface of PVC/uPVC/WPC/PVC foam/MDF profiles, such as window profiles, wall panels, panel ceilings, corrugated panels , door frames, wall skirting and corners by solvent polyurethane glue.
◆ It matches Primer Coating Device which is necessary for uPVC window profiles.
◆ It matches automatic deviation rectify to adjust PVC film running in correct way.
◆ It also match protective film wrapping device after laminating PVC film.
◆ It adopts “Two Components Polyurethane Adhesive” to stick PVC film with profiles well.
◆ Just for uPVC or PVC window profiles, it needs to adopt good quality of PVC film to bear sunshine, the best quality of PVC film is from Germany, Renolit Film.
(the profiles can be decorated by this machine)
