Coating Die Head

Coating Die Head type

Fixed Lip Coating Die Head

◎Simple structure, low cost, and more universality;

◎Customized cavity structure, suitable for different coating fluids with different characteristics;

◎The opening of the die lip is adjusted by replacing gaskets with different thicknesses, combined with high-precision die lips, resulting in good uniformity of coating;

◎Quick opening and closing of the die structure, convenient for cleaning and maintenance.

Three Layers Composite Coating Die Head

◎Three independent cavity designs that can be coated in three layers simultaneously;

◎Quickly open and close the die structure, allowing each layer to quickly open and clean the flow channel;

◎High accuracy die lip and good coating uniformity.

Surface Treatment (DlC Coating Treatment)

◎Super wear resistance, Vickers hardness can reach HV2000-2300;

◎Excellent lubricity, friction coefficient of 0.06-0.1, preventing adhesive wear;

◎The film thickness can be adjusted according to the size of the die head, with a thickness of 1-10um on one side and low tolerance;

◎Excellent anti-corrosion performance.

Die Head Pad

◎Adopting imported pad, low tolerance and the high precision;

◎The pad material can be selected: SUS304, 316L;

◎Different thicknesses of pad can be selected based on the coating thickness;

◎Changing the opening size of the U-shaped pat can adjust the coating width.
