Composite extrusion casting machine, some manufacturers and users of occupation habits called laminating machine, also known as extrusion machine, casting machine, extrusion casting machine, casting compound machine, coating machine, coating machine, coating machine (not accurate, practice refers to the hot melt coating machine scraper), is a kind of extrusion molding machine. Has a high degree of automation, simple operation, high production rate, uniform coating thickness, high adhesion, coiling flat, no environmental pollution, saving labor and material costs and other advantages, in Europe and the United States has carried out sophisticated, these years in China gradually began to use, is to replace the dry compound, hot melt coating composite trend.
In practice, after photos, canvas appearance with oily liquid with thin layer width of about one meter of small equipment is the real "shower" film machine, usually used for studio and other occupation, to ordinary life with small machinery. And the high speed, large width of the composite data line is attributed to light industrial machinery, according to packaging, printing and mechanical production standards, should be called "extrusion tape casting unit". Search results on Google and Baidu Chinese laminating machine and other domestic search engine and most B2B, B2C or portal for laminating machine information is both, and photo film machines accounted for the majority of people, simple hybrid.
Process of coating machine principle
Extrusion casting molding plastic particles by screw extruder by die die extrusion line, after drawing attached to the paper, film, woven fabrics, woven cloth and other flexible substrate surface, the composite material strength and function characteristics of cooling pressure synthesis both plastic film layer barrier and heat seal and base material.
The film group composition
The whole machine is composed of feeding equipment, extruder, main machine, mould, coiling organization, compound organization, coiling organization, edge manipulation equipment, trimming equipment, heating and cooling system, electric measurement and control system, etc.. According to the difference, the product requirements can be increased by second, the unwinding organization, the printing equipment, the oven, the substrate, the surface treatment equipment (Corona machine, etc.), the on-line thickness measuring instrument and so on. Pre process equipment: granulator, printer or other equipment, rear process equipment: slitting machine or other equipment.

The main effect of the coating machine
Small laminating machine designed for special equipment department photo and packaging film
Do large paper plastic composite film class, lamination unit is of high pressure polyethylene (LDPE), OPP film, paper cups, paper carton, label paper, paper bags of seeds, cleaning bag paper and aluminum foil, plastic film, cloth and other material for single film, double-layer film coating equipment.
After the photos, canvas surface with oily liquid, film layer of the width of about one meter of small equipment is the real "pour" film machine, usually used for studio and other occupations, attributed to the daily life of small machinery. And the high speed, large width of the composite data line is attributed to light industrial machinery, according to packaging, printing and mechanical production standards, should be called "extrusion tape casting unit". Now the search results on Google and Baidu Chinese laminating machine and other domestic search engine and most B2B, B2C or portal for laminating machine information is both, and photo film machines accounted for the majority of people, simple hybrid.
Suitable for laser printing, inkjet photo film, coated paper, paper laminating adhesive
Oily film features: waterproof, moisture-proof, anti aging, anti UV, high yield, and can be repeatedly lossless image, film. The film liquid directly attached to the image appearance by ultraviolet light after curing, should not fall.
The main advantages compared with water film: oily film products after more waterproof, sunscreen, deformation, and wear resistance.
PS: permeability increased by more than fifteen percent, can be recycled plastic film liquid, convenient no waste, fast speed and low cost.
