Advantages of vacuuming when screen printing silicone

Advantages of vacuuming when screen printing silicone:
1. Eliminate bubbles
Improve printing quality: During the process of screen printing silicone, if there are bubbles in the silicone, defects will form at the bubbles after printing on the substrate, affecting the integrity and clarity of the pattern. Vacuuming can effectively expel the air in the silicone and reduce the generation of bubbles, thereby ensuring that the printed pattern is smooth, uniform and flawless.
Enhance adhesion: The presence of bubbles may cause insufficient contact between the silicone and the substrate, affecting the adhesion of the silicone. After removing the bubbles by vacuuming, the silicone can better fit the substrate, improve adhesion, make the printed pattern more firm and not easy to fall off.
2. Ensure the fluidity of silicone
Uniform coating: Vacuuming can make the silicone flow more evenly under the action of pressure difference, ensuring that the silicone can be coated on the substrate with a stable thickness and form during the screen printing process. This helps to achieve precise pattern printing and consistent printing effects.
Avoid uneven thickness: If there are bubbles in the silicone, it will interfere with its fluidity, resulting in uneven thickness of the silicone layer after printing. Vacuuming helps eliminate this unevenness, making the thickness of the silicone layer more uniform and improving the appearance quality of the product.
3. Improve production efficiency and stability
Reduce scrap rate: By vacuuming to remove bubbles and ensure the uniformity of silicone, scrap caused by quality problems can be greatly reduced, and production efficiency and economic benefits can be improved.
Stabilize the production process: Vacuuming can make the process of silk-screen silicone more stable and controllable. It avoids interference from factors such as bubbles on the printing process, reduces adjustments and rework required due to quality fluctuations, and thus improves production stability and reliability.
