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.
