What’s the advantage for using chamber doctor blade in flexo printing?

1.Prevent ink rejection and improve production efficiency

The normal operating speed of an open single squeegee is generally below 120m/min. After this speed, the phenomenon of ink rejection or glue rejection will often occur; the use of a closed cavity hanging knife system can effectively prevent ink rejection or glue rejection (prevent printing ink Or glue splash), which can improve the operation of the equipment and increase the production efficiency.

2. Reduce volatilization, save costs, stabilize viscosity, and protect the environment

2.1 Solve volatilization problems and save production costs

When using an open doctor blade, because the ink or glue is exposed to the air, volatile substances and moisture will volatilize into the air, causing cost waste, also polluting the environment and affecting the PH stability of the ink or glue; The chamber doctor blade system can effectively overcome these problems.

3. Avoid ink precipitation

Since the ink or glue is circulated when using the chamber doctor blade system, the precipitation of ink particles is avoided.

4. Prevent uneven ink scraping

When using an open doctor blade, due to the instability of the doctor blade body, the pressure between the blade and the anilox roller is different, so that uneven scraping and an abnormal sound appears during printing or coating. The use of chamber doctor blade system with stable structure and high processing accuracy can effectively avoid such problems.
