Split Coating Heads

A Split Coating Head is a 2 piece die product that employs a stationary half of a coating chamber with a 'loose' or removable piece (second half). The coating chamber is open when the substrate is being aligned on the draw, and closed when the substrate is aligned in the coating chamber. The coating is then fed into the chamber and the draw continues. Split Coaters are size specific to each mission, and therefore are most practical if the user is making short runs, or if jamming or substrate upsets occur often. The Split Coater is easy to maintain, clean and restart if jams or other draw problems occur. 

Solid Coating Heads

Solid Coaters consist of a body containing 2 separate dies to form a coating chamber. The dies are changeable and allow the user to deal with substrates of different diameters and coatings with varying characteristics. Since the entrance and exit dies can be changed at will, these coaters are more versatile. They are preferred for longer runs and for runs where the substrates are less likely to jam, break or otherwise stop the draw prematurely.

Wet on Wet Coating Heads

Wet on Wet Coating Heads are hybrid coaters that give the user the ability to apply 2 coatings in-line without sacrificing speed, concentricity or size. Naturally the coatings must be compatible with each other, but that's a plan that the user will work out with the coating supplier. Sancliff’s Fiber Optic Cladding Dies, Coating Dies, Fiber Optic Coating Head Assemblies and Fiber Optic Pressurized Coating Systems are engineered to deliver controlled supplies of diverse chemical composition and varied viscosity coating to our Fiber Optic Coating Head and Die Assemblies.

Cladding and Coating devices are available in split, solid, wet on wet, twin and multi configurations for conventional round and/or specialty shaped fibers and substrates. Low and even pressurization of the Sancliff, Inc. Fiber Optic Coating Head chambers assists in the control of the size and application of concentric coating material upon the specified substrate, as well as preventing meniscus collapse as the fiber enters the coating chamber. From ultra-thin to heavy Claddings and Coatings, Polyimides or Acrylates, high speed or low speed, there is a Sancliff Coating System and Coating Head to meet your needs.
Sancliff, Inc. Fiber Optic Coating Dies and Head Assemblies control the thickness and concentricity, as well as apply a protective layer of specified coating over the bare or coated fiber during the drawing or re-coating process. This protects it from the environment that the material will be exposed to. Applied acrylate or polyamide coatings on the bare glass or previously coated fiber also provide protection from mechanical damages such as cable or fiber bending, and/or kinking. This prevents the ingress of moisture into the microscopic flaws on even the most pure glass preforms.
