JWELL Double Layer Sliding Curtain Coating Die Head
JWELL Double Layer Sliding Curtain Coating Die Head uses a superimposed die design with two parallel flow channels for simultaneous two-layer coating, with high-accuracy die lips for good coating uniformity.
Key Points
- Superimposed die design with simple structure and low processing difficulty
- Two parallel flow channel design allows for simultaneous application of two layers of coating fluid, with a wide range of applications
- High accuracy die lip and good coating uniformity
Precision Slot Coating Die
The slot coating process transports a stable and quantitative coating liquid under a certain pressure from the material flow system to the die head cavity through the die head inlet, then evenly distributes it across the full die width through the internal manifold or cavity. It is extruded along the die opening gap and transferred to the substrate surface. The die head is a key component of slit coating, and the ultra-high precision of the die head is a key factor in ensuring coating uniformity.
Characteristics Of Slot Coating Process
- High coating speed and good consistency of film thickness
- The viscosity of the coating fluid has a wide range of applications
- Less coating defects and high utilization rate of coating fluid
- Two or three layers of coating can be applied simultaneously
