Screen Mesh Count:
For thicker silicone layers, a lower mesh count screen is typically used. A lower mesh count means larger openings in the screen, allowing more silicone to pass through and form a thicker layer.
Screen Thickness:
A thicker screen can accommodate more silicone, facilitating the formation of a thicker silicone layer. However, screen thickness also affects the flexibility and durability of the screen, which needs to be balanced with the printing requirements.
Screen Tension:
Proper screen tension is crucial for maintaining the stability and flatness of the screen during printing. For thicker silicone layers, an appropriate level of tension is needed to ensure even silicone distribution and prevent issues like uneven thickness or smudging.
Squeegee Pressure and Angle:
To print a thicker silicone layer, greater squeegee pressure may be required to push the silicone through the screen. Additionally, adjusting the squeegee angle can affect the amount of silicone transferred and the resulting layer thickness.
Printing Speed:
Printing at a slower speed can allow more time for the silicone to pass through the screen and form a thicker layer. However, this also reduces production efficiency, so a balance needs to be struck between thickness and speed.
