Screen printing operators often face equipment faults that affect print quality and production efficiency.
1. Uneven ink distribution
Uneven ink distribution is a common problem that can lower print quality and slow down production.
Check the ink supply system to ensure steady and uniform delivery.
Clean the ink reservoir and ink pipes to prevent blockages that restrict ink flow.
Adjust the squeegee angle and pressure so that ink coats the screen evenly.
2. Screen clogging
Clogged screens can cause print defects or complete printing failure.
Clean screens regularly to remove dried ink, residue, or other contaminants.
Use appropriate cleaning agents and tools to keep the mesh surface smooth.
Check and adjust screen tension to prevent deformation or looseness.
For repeated clogging caused by worn screen frames or incorrect mesh tension, Hansheng Automation can custom-manufacture replacement frames and tensioning blocks according to customer drawings or sample parts.
3. Screen detachment or damage
Screen detachment or breakage reduces print quality and may stop production.
Inspect screen tension periodically to keep it within the correct range.
Select suitable screen materials and printing parameters to reduce the risk of breakage.
Replace aged or damaged screens promptly to maintain consistent output.
4. Unstable machine operation
Unstable operation can cause misalignment, inaccurate color, and other quality problems.
Regularly inspect the transmission system, including belts and chains.
Adjust machine speed and pressure for a more stable printing process.
Perform routine maintenance, cleaning, and lubrication of key components.
Conclusion
Screen printing machine faults can be managed through regular inspection and proper maintenance. Regular upkeep and timely replacement of worn parts support consistent print quality and longer machine life.
