Our extensive experience can help create or improve your new slot die coating roll design.

Our designs are crafted for maximum accuracy and consider these factors:

Load conditions
Bearing selection
Base metal materials
Viscosity
% Solids
Coating thickness
Particle size
Coating width
Line speed

What is Slot Die Coating?

Slot Die Coating is the standard for thin accuracy in the web handling industry. These rolls offer uniformity and quality as well as pre-metering of the liquid coating to ensure it is all applied to the substrate. This process can range from thick coating down to micron-measured.

Advantages include:

Closed system
Maintained temperature
Uniformly distributed fluid
Defined coat width
Increased production speeds
Positive coat weight control
Improved waste management
Cross-web distribution control
