FAQ

• Q: How do you ensure alignment between different coating layers?

  • A: We use a customized edge guiding or vision-based registration system that makes micro-adjustments to ensure layer-to-layer accuracy.

• Q: Can we switch between UV and solvent-based coatings on the same line?

  • A: Absolutely. The line can be customized with a combination of UV curing stations and thermal drying tunnels to handle hybrid chemistry processes.

• Q: Is this line suitable for both flat and slightly textured sheets?

  • A: Yes, within limits. The roller coating head can be customized with different roller hardness to accommodate slight texture while maintaining film uniformity.
