A suitable coating machine for every application
Various coating possibilities are available to cover all the different application cases:
- Direct emulsion
- Capillary film
- Pre-coated PCF mesh
Nowadays, the most frequently used method is direct emulsion coating. Important is, that the emulsion is standardized – automatically and reproducible – applied by a coating machine. The selected printing process determines the type and quality of coating. In this respect, the following parameters are of utmost importance:
- Coating thickness in micron (EOM)
- Surface roughness in micron (Rz)
- Resistance (water- or solvent-based ink)
- Necessary resolution / printing fineness
- Print run and print resistance
- At any rate, the use of the right kind of emulsion is a key factor that can save you a lot of money.
The choice of the appropriate coating machine is influenced by various key factors, such as:
- Screen size
- Screen quantity per day
- Sequence of operations
- Space available
- Budget
Automation thanks to magazine technology: The modular magazine systems have been designed for automatic loading and unloading of printing screens. These magazines complete all GRÜNIG IN-LINE systems in the G-WASH or G-COAT sectors. For practical purposes, this solution means: Upon loading the screens and starting the process, all the screens are automatically processed without any intervention from the operating staff.
