Extrusion cast laminating machine, also known as extrusion laminating machine, cast machine, extrusion cast machine, cast laminating machine, film coating machine, plastic coating machine, coating laminating machine (inaccurate, actually refers to the hot melt adhesive scraper coating machine), is a kind of extrusion molding 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 lamination, hot melt adhesive coating composite of the inevitable trend.
One, the introduction of film laminating machine.
In fact, through the photo, canvas surface with oil-based liquid dripping on the film layer of the width of a meter or so of small equipment is the real "dripping" film machine, generally used in the studio and other industries, belong to the daily life of small machinery. High speed and large width composite production lines are light industrial machinery and should be called extrusion cast laminating units according to industry standards for packaging, printing and machinery manufacturing. Google Chinese and Baidu and other domestic search engines on the laminating machine search results and most B2B, B2C or portal information on the laminating machine is the coexistence of the two, and photo laminating machine accounted for most, easy to make people confused.
Secondly, the process principle of laminating machine.
Extrusion cast molding: plastic particles are plasticized by a screw and then extruded in a linear pattern by a flat die head die opening, stretched and attached to the surface of flexible substrates such as paper, film, non-woven fabric and woven fabric, and then cooled and shaped and pressed into a composite material with the barrier and heat sealing properties of the plastic film layer and the strength and functional properties of the substrate.
Three, laminated film machine structure composition.
The machine is composed of feeding device, main extruder, mould, unwinding mechanism, laminating mechanism, winding mechanism, side control device, edge cutting device, heating and cooling system, electrical measurement and control system, etc. A second unwinding mechanism, printing equipment, ovens, surface treatment devices for substrates (corona machines, etc.), online thickness gauges, etc. can be added according to the needs of different products. Pre-process equipment: granulator, printing machine or other equipment; post-process equipment: slitting machine or other equipment.
Fourth, the categories of laminated film
(1), according to the extrusion speed classification
1. Low speed extrusion cast laminating machine
2. Medium speed extrusion cast laminating machine
3. High speed extrusion cast laminating machine
(2), according to the number of layers of substrate classification
1. Single substrate laminating machine
2. Multi-substrate laminating machine
3.Three in one substrate laminating machine
(3), classification according to the type of substrate
1. Paper laminating machine
2. Plastic film laminating machine
3. Non-woven/non-woven laminating machine
4. Woven fabric laminators
5. Mesh laminating machine
6. Other substrate laminating machines
Five, the application scope of film laminating machine
1、Food industry
2、Packaging industry
3、Beverage industry
4、Pharmaceutical industry
5、Copy and printing office industry
6、Engineering and construction industry
7, other composite flexible packaging materials manufacturing
Six, the main role of laminating machine
Small laminating machine is designed for photos and packaging laminating special equipment
Large is to do paper-plastic composite film, laminating composite unit, is the high-pressure polyethylene (LDPE), OPP film, paper cup paper, paper box paper, trademark paper, melon bag paper, cleaning bag paper and aluminum foil, film, cloth and other substrates for single-layer laminating film, double-layer laminated film laminating equipment.
Small machines with a width of one metre or so are the real "laminators", generally used in studios and other industries, and are small machines for everyday use. The high speed and large width composite production line is a light industrial machine, which should be called an extrusion flow compounding unit according to industry standards for packaging, printing and machinery manufacturing. At present, the search results of Google Chinese and Baidu and other domestic search engines for laminating machines and most of the information on B2B, B2C or portal sites about laminating machines are both, and photo laminating machines account for the majority, making it easy to confuse people.
Suitable for lamination of laser printing, inkjet printing, lamination of coated paper and adhesive backed paper
Oil-based lamination is characterised by its waterproof, moisture-proof, ageing-proof, UV-proof and highly productive nature, and can be repeatedly laminated. The lacquer is directly attached to the surface of the picture and cured by ultraviolet light, and should not be peeled off.
The main advantages over water-based lamination are: the finished product is more waterproof, sun-proof, non-deformable and more wear-resistant.
PS: The permeability is increased by more than 15%, the lacquer solution can be recycled, the lamination is easy and waste-free, and the speed and cost are low.
