Advantages of PUR Hot Melt Adhesive Machine 1, PUR hot melt adhesive machine’s press plate is processed by precision aluminum alloy casting, and CNC processing. The outer surface of the heating plate is coated by teflon, it is not easy to fall off and so on. 2, Air is isolation with melting device’s innder side, there o-ring seal between the inner wall of the melting device’s innerside plate, so it make sure glue won’t contact with air, this ensure the working conditions for PUR machine. 3, PUR hot melt glue machine’s glue is easy to clean, this can effectively prevent the carbonization of glue, make sure the glue quality is best, reducing the plugging of the system.
