In screen printing, how to adjust the process parameters to make the silicone level faster
1. Screen and scraper optimization
Screen selection:
High mesh screen (120-200 mesh): reduce ink deposition and reduce leveling resistance (suitable for fine patterns).
Conical mesh: hole wall inclination 45°-60°, so that the ink release is smoother and the edge accumulation is reduced.
Scraper parameters:
Hardness 70-80 Shore A, angle 60°-75°, pressure 0.3-0.5MPa, to ensure uniform ink transfer and controllable layer thickness (recommended thickness ≤0.1mm).
2. Segmented printing technology
Operation steps:
The first thin print (thickness about 0.05mm), let it stand for 5 minutes for initial leveling.
The second reprint to the target thickness (total thickness ≤0.15mm), use the lubrication of the first ink layer to accelerate the secondary leveling.
Advantages: Compared with single thick printing, the leveling time is shortened by 30%-50% and the residual bubbles are reduced.
