Characteristics of several coating methods -

Stainless steel scraper
The scraper is sheared by a stainless steel sheet and pressed against the blade holder and applied to the upper (coating) rubber roller. Since the stainless steel sheet is soft, the squeegee is not very uniform, and most of the squeegee used on the anilox roll is also used for pre-scraping of the glazing coating.

Comma scraper
Such scrapers are often made of round steel with good strength and hardness. The blade is fixed and does not rotate when the glue is scraped. The strength of the scraper is high, the hardness of the blade is small, and the pneumatic and fine adjustment mechanism can be used to adjust and control the position of the scraper. The coating amount control and the scraping precision are high, and the use is also extremely convenient. Due to its uniform squeegee, it is suitable for precise squeegee coating on smooth rolls.

Bar scraper
This type of scraper is usually made of round rods with good strength and hardness. The round bar is required to rotate when scraping the glue. Sometimes the bar can also be scraped directly onto the substrate. The full runout error of the scraper bar is very small, and it is mostly used for the pre-squeegee coating of the glue bar coating on the light roller. When the glue is sticky, it can also be directly scraped on the substrate with a scraper as a precise scraping agent for the coating mechanism. It can also be used for coating a thicker disposable squeegee.

Various optical films, protective films, film films, matte flexible packaging films.


Slot-Die Coating:
     The Slot Die coater is a high-precision coating method in which the coating glue is pressed from the reservoir to the nozzle through the supply line, and the glue is ejected from the nozzle to be transferred to the coated substrate.
advantage:
1. The coating effect is good, and the coating amount is flexibly controlled by the micro-motion adjustment of the coating blade, and the coating precision is high.
2. It can coat the discontinuous mode, and the coating range can be adjusted freely. It does not need to use the baffle plate, and it will not produce the stain phenomenon caused by the difference in edge thickness.
3. Cleaning and disassembly is easier.
4. Helps to maintain a clean, high level, the channel through which the glue flows as a whole can be sealed to prevent the entry of other contaminants.
Disadvantages:
1. The partial structure of the entire Slot-die coating head is complicated, and the processing precision of the rubber roller, the coating roller, the traction roller and the scraper is required to be high, so the cost is higher than other coating methods.
2. Due to the high precision, it is difficult to use and operate.
