Common Troubleshooting of Screen Printing Machine

Screen printing machine troubleshooting is crucial for ensuring smooth production, reducing downtime and improving product qualification rate. Whether in small-batch processing or large-scale production, mastering common screen printing machine problems and their solutions can effectively avoid losses and enhance work efficiency. Below are the most common faults and corresponding solutions, along with professional maintenance tips.

 1. Ink leakage: The main reasons are damaged screen mesh, improper ink viscosity or uneven scraper pressure. Solution: Replace the damaged screen, adjust ink viscosity with thinner, and calibrate scraper pressure to ensure uniform force.

 2. Misregistration: It is usually caused by loose screen frame, inaccurate positioning or unstable machine operation. Solution: Tighten the screen frame, check and adjust the positioning device, and ensure the machine is placed on a flat surface to avoid shaking.

 3. Ink peeling: This is due to insufficient substrate pre-treatment or mismatched ink and substrate. Solution: Clean the substrate surface to remove oil and dust, and select ink that matches the substrate material.

 4. Machine jamming: Common causes include foreign objects in the transmission part or lack of lubrication. Solution: Turn off the power, remove foreign objects, and add lubricating oil to the transmission parts regularly.

Professional maintenance tips: Clean the screen printing machine after daily use, check vulnerable parts regularly, and replace worn parts in time. If you encounter complex faults that cannot be solved, it is recommended to consult professional after-sales support to avoid secondary damage to the machine. Proper troubleshooting and maintenance can extend the service life of the screen printing machine.
