Shims and Meniscus Guides

About

Shims & Meniscus Guides | Specifications | Technical Support Shims and meniscus guides to control the flow of solution through your slot die head. Shims to vary the coating width for your deposition. You can also stack multiple shims to increase the deposition channel width to optimize the flow of solution through the head. To improve the edge quality, meniscus guides can be added, which stop the meniscus from spreading along the width of the head. For more specific requirements, we also offer custom coating guides which allow for multi strip coatings. We would recommend using both at least a meniscus guide and a shim with our slot-die coater to ensure the best coating.

Desired Coating Width Thickness Lip Depth (Meniscus only) A range of coating width, thickness and lip depths are available for each shim design. We also offer custom options and designs to enable multi-strip coatings. The high viscosity slot die coater requires high viscosity shims and meniscus guides.

For best coating, meniscus and shim coating widths should be complimentary (i.e. 75 mm shim with 75 mm meniscus guide). Viscosity The high viscosity and standard viscosity shims/meniscus guides are designed with different distribution manifolds, which are optimized for different solution viscosities. Using the co
