Laminating machines can be divided into two categories: ready-to-coat laminating machines and pre-coating laminating machines. It is a special equipment for paper and film. The coating laminating machine includes three parts: gluing, drying and hot pressing, which has a wide range of application and stable and reliable processing performance, and is a widely used laminating equipment in China. The pre-coated laminating machine, without gluing and drying parts, is small in size, low in cost, flexible and convenient in operation, and is not only suitable for laminating large quantities of printed matter, but also suitable for laminating and processing of small batches and scattered printed matter such as automated desktop office systems, which is very promising [1] .

The operation of this kind of equipment includes gluing, drying, hot pressing three parts, the operation is higher, the advantage is that the quality of the finished product is reliable, and it has a fatal disadvantage that oil-based rubber processing will produce gas that affects human health, so this technology has been completely banned in developed countries such as Europe and the United States, water-based glue is more environmentally friendly than oil-based, and the relative oil-based cost is higher.

1. The base, wall panel, etc. are constructed of cast iron, which will never be deformed, so as to ensure that its accuracy will not be affected during the use process and maintenance and replacement of parts.
2. The rubber coating roller and the limited rubber roller are made in fine workmanship, and the concentricity error of the roller surface is controlled within 0.01mm to ensure uniform gluing and save the amount of glue.
3. Thermal composite steel roller precision mirror treatment, laminated finished product is excellent.
4. Electronic automatic thermostatic device.
5. The hydraulic system is uniquely designed, precise and stable.

Water-based and oil-based dual-purpose machines can be customized according to user requirements.

Pre-painted type
This kind of machine lamination is a one-time molding, the consumables used have been coated with glue, and the glue is melted by heating, and then the film is bonded to the printed matter by pressurization. This kind of laminating equipment is cheap, simple to operate, and does not produce harmful gases during operation, is a trend of laminating development, in today's society that pays more and more attention to environmental protection, it is believed that this technology will one day replace the pre-coating film of both coatings, and become the main laminating technology in the domestic printing industry. Its disadvantage is that this technology is not very mature in China, and there are still some problems to be solved, such as: single-sided film curling (there are single-sided anti-curling machines, but the price is higher), printing with silicone oil is difficult to laminate, etc. It is widely used in short-run printing and digital fast printing industries.

That is to say, it is a simple and practical professional laminating machine, which can also be used as a plastic laminating machine, a cold laminating machine, and PVC heat sealing. But this kind of laminating machine solves the fundamental problem of the first type of laminator, the price of the laminating machine is between {{0}} yuan, due to the use of internal hot rubber roller to press the film, up and down the film, increase the heating time of the pre-coated film, and the heating balance, so the film covered out, flat, bright, and the film effect of the high-grade laminating machine is the same. However, this kind of laminating machine has a heating power of only 500W, although the temperature is adjustable but the speed is fixed, and the film can be pressed 0.7-0.8 meters per minute. It is suitable for business card lamination, recipe lamination, photo lamination and graphic and text printing lamination, especially in some small printing factories, typing and copying shops, business card production agencies and photo studios, in order to reduce equipment investment and reduce costs, so there are more people who choose this kind of laminating machine. The market prospect of this kind of laminating machine is very good, and it can be said that this laminating machine is the most cost-effective.
