Fixed lips are static and ideal for repeatable processes.

Shimmed lips allow fine gap adjustments via spacers.

Adjustable lips offer dynamic control during operation, ideal for R&D and variable specs.

Fluid viscosity, coating speed, lip design, and substrate surface energy all play a role. We tailor die geometry to minimize edge defects and maintain bead shape.

We provide installation guides, remote support, and on-site assistance as needed. Our goal is to ensure smooth integration and fast ramp-up.

Coating defects often result from poor fluid distribution, misaligned lips, or contamination. Prevent these issues with regular maintenance, proper setup, and a well-matched die design.

Lead times depend on project complexity, but most custom dies ship in 6–10 weeks. Lip inserts and top lip fixes may take about 5 days to 2 weeks. New coating or extrusion dies under 1000 mm typically take 6–8 weeks, and larger dies over 1000 mm usually take 10–12 weeks. Rush options may be available for urgent needs.

Slot die coating offers superior thickness control, minimal waste, and scalability from lab to production. It’s cleaner, more repeatable, and more efficient than methods like knife-over-roll or dip coating.

To optimize coating processes with rheology testing, analyze fluid viscosity, shear response, and flow stability under various conditions. This data helps determine the ideal coating speed, gap, pressure, and die configuration. Rheology testing also identifies potential issues like edge bead, ribbing, air entrainment, and flow instability before they impact production. By applying these insights, you can achieve consistent coating quality, reduce waste, and enhance production efficiency.

Precision Die Systems offers rheology testing services through a partnered test lab to optimize coating processes. Our experts analyze fluid viscosity, shear response, and flow stability from test results to recommend adjustments that improve coating uniformity and reduce defects. Data from viscosity versus shear rate in reciprocal seconds determines flow channels and internal geometry optimizing coating process. Contact us to schedule testing with our Wisconsin facility.
