Optical Fiber Coating Dies And Applicators
Optical Fiber Coating Dies And Applicator
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.
Split Optical Fiber Coating Die Applicators
A Split Coating applicator, also commonly referred to as a “Head” is a 2 piece split ID hole die that employs a stationary half of a coating chamber with a retractable side. When closed they form a pressure chamber to apply the coating to the chosen substrate. The coating chamber is open when the substrate is being aligned on the draw tower, and closed when the substrate is aligned in the coating chamber. The coating fluid 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 Optical Fiber Coating Die Applicators
Solid Coating applicators consist of a body containing 2 sealed dies to form a coating chamber. The “Solid” refers to the ID hole of the die insert. The dies are replaceable and interchangeable which allows the user to match Dies 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.
Split Optical Fiber, Wet on Wet Coating Die Applicators
Split 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 and will cure with a single device such as a UV Fusion Lamp. 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.
Solid Optical Fiber, Wet on Wet Coating Die Applicators
Solid Optical Fiber, Wet on Wet Coating heads have developed a great deal in recent years. Sancliff has perfected a very versatile Quad die design that allows the end user greater flexibility to mix and match sizes for differing incoming and finish parameters as well as deal with a dreaded fiber jam.. As with any Sancliff optical fiber WOW die this die can be used as a single stage coating applicator at any time.
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.
