Precision Narrow Slot Coating Die
The slitting coating process involves feeding a stable, quantitative coating liquid under pressure through a feed port into the mold cavity of a die, from where it is then transported via internal channels or cavities within the die.
Evenly distributed across the entire width range of the die, extruded along the mold opening gap and transferred to the surface of the substrate. The die is a critical component of narrow gap coating, with ultra-high die accuracy ensuring the coating
Key factors for uniformity.
Features of slit coating technology
High coating speed and consistent film thickness quality
Coating liquid has a wide range of applicability for viscosity.
Low coating defects, high coating liquid utilization rate
Can perform double or triple coating simultaneously.
Three-layer composite coating die
Three independent cavity designs, capable of simultaneous triple coating
Quick-action mold structure, each layer can be quickly opened and cleaned
Flow channel
High mold lip accuracy, excellent coating uniformity.
Double-layer slider coating die
Stackable mold design with simple structure and lower processing difficulty.
A two-layer parallel channel design that allows for the simultaneous application of two coating liquids, with a broad range of applications.
