Extrusion cast laminators, which some manufacturers and users in the industry are used to calling film laminators, are also called extrusion laminators, cast machines, extrusion cast machines, cast laminators, film coating machines, plastic coating machines, coating laminators (inaccurate, actually refers to hot melt adhesive scraper coating machines), and are a kind of extrusion forming machinery. With a high degree of automation, easy to operate, high production speed, uniform coating thickness, high bonding fastness, rolled flat, environmentally friendly, pollution-free, save labor and raw material costs, etc., in Europe and the United States has developed mature, in recent years, the domestic gradually began to apply, is an alternative to dry composite, hot melt adhesive coating composite inevitable
The trend.
Extrusion cast molding: plastic particles by the screw plasticized by the flat die head die mouth into a linear extrusion, stretching attached to paper, film, non-woven fabric, woven fabric, etc,
Film, non-woven fabric, woven fabric and other flexible substrate surface, cooling and pressing into both plastic film layer of barrier and heat sealing
The composite material combines the barrier and heat sealing properties of the plastic film layer with the toughness and functional properties of the substrate.
Structure
The machine consists of a feeding device, an extruder, a mould, a rewinding mechanism, a laminating mechanism, a winding mechanism, a side control device, a trimming device, a heating and cooling system, an electrical measuring and control system and other components. A second unwinding mechanism, printing equipment, oven, substrate surface treatment device (corona machine, etc.), online thickness gauge and other components can be added according to the needs of different products.
