The workflow of the coater

The coating machine roughly includes: coating, drying, hot pressing, cooling、... and other units

(1) Coating unit

According to different machine designs, the coating and gluing methods include roller coating and scraper coating. The glue coating surface is also different on the cloth above, below or on the film, different gluing methods make the glue penetrate and form a film on the substrate is different, of course, the effect of the next is also different, in addition, the presence or absence of the texture on the coating wheel, and the pattern of the grain will also affect the difficulty of the glue and the form of the glue coating (full coating, point coating...). The coating wheel with special grain and the corresponding glue can even be combined to produce high-performance finished products, such as breathability and ultra-soft feel.

(2) Drying unit

The availability or length of the oven and the type of drying (hot air circulation or infrared-assisted) also vary depending on the type of oven and the roller or scraper coating. The volatilization rate of the glue solvent is closely related to the drying conditions of the machine, so adjusting the temperature required for the material is crucial to ensure that the adhesion still has good adhesion.

(3) Hot pressing unit

The size of the pressur, the surface temperature, and the length of the pressurization time will be related to the volatilization efficiency of the residual solvent, the activation degree of the glue and the quality of the lamination effect.

(4) Cooling unit

Before the laminated product is curled, it is cooled by the cooling wheel, which can promote the crystallization of the glue, improve the initial adhesion force, and avoid the displacement of the laminated material during winding.
