1. High precision alloy steel die head make sure the customer can get the best coating effection.
2. Total Machine is controlled by PLC.Precision control coating speed and glue amount.
3. Increase the film function in some glue or substrate is not suitable for direct knife coating that realize 2 kinds of craftwork (knife coating and film coating.) on one machine.
Comma roll coating application case:
- 2 -
Various optical films, protective films, film films, matte flexible packaging films.
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.
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.
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.
