Plastic Extruder Screw/Single Screw for Plastic Extruder
Insulating glass machines are special machines for manufacturing insulated glass. Insulated glass is a combination of two or more sheets of glass spaced apart with a spacer bar and hermetically sealed with a primary and secondary sealant to form a single unit with one or more air or inert gas spaces in between, with benefits of energy saving, sound insulation, reduced infiltration, and reduced condensation. The major manufacturing process for insulated glass includes glass cutting, glass edging, glass washing and drying, spacer assembly, pressing, sealing, and gas filling. insulating glass machine mainly includes Vertical Insulating Glass Production Line, glass cutting machine, glass washing and drying machine, glass edging machine, butyl extruder, two-component sealant extruding machine, gas filling machine, and so on.
