This Optical Fiber Coloring Machine is made for operator skill independent use within production and laboratory settings. Two basic model configurations enable the user to pick between a setup for standard linear proof testing and with additional mandrels for rotary high strength testing.
The linear version is made for production proof testing with forces up to 22 N. Motorized clamps with carefully designed rubber inserts be sure that the fiber coating will not be damaged inside the testing process while concurrently eliminating the requirement for an outside air supply. Amounts of pulling force, pulling speed and hold time are programmable and conveniently available to the operator from the built in LCD touch-screen control. Data from tests can be saved and accessed via the USB port or Ethernet interface.
Mandrels the exact same design like NYFORS’ optical fiber recoaters may be easily mounted on the proof tester inside the rotary high strength configuration. The fiber is wrapped round the two mandrels which support it using a special clamping mechanism. By doing this greater loads can be applied onto the fiber, enabling breaking strength tests under controlled circumstances.
Adjustable clamp positioning facilitates testing using the highest force levels along with testing of short fiber lengths. The compact and light-weight weight design makes the instrument easy to maneuver in a laboratory environment as well as integrate in a production work bench where space are at reasonably limited. The equipment is a compact and light-weight instrument suitable for testing the strength of optical fibers up to 30 N. The device is created to meet all types of applications in which a strength test has to be performed.
The machine was created with all the user in mind. The fiber is readily positioned in the guided linear clamps, and also the testing starts automatically using a “One Touch” go button. The built-in microprocessor controls each of the important parameters such as pulling force, pulling speed and hold time. This enables for a completely controlled test each and every time.
The Secondary Coating Line could be attached to another PC, which enables use of all programmable parameters and settings. The device is adapted to stand-alone use or even to the integration into different subsystems. The equipment posseses an extensive capability of logging and saving information including pulling force, pulling speed and fiber diameter and other parameters.
Two recoat injector configurations can be purchased. The PTR307 uses a computerized pump to inject the recoat material. The amount of material dispensed by the automatic injector is controlled manually through the top-mounted “Inject” button or programmed to the machine utilizing the tablet controller. The PTR307B includes a manual recoat injection system that needs the fseejm to manually dispense the recoat material into the mold cavity; a substitute injector for the PTR307B recoater can be obtained below. Please note the automatic injector is only suitable for high-index recoat material, as the manual injector works with both low- and high- index recoat material; they are both sold separately below. Please contact Tech Support for more information.
he manual injector could be mounted to compatible Optical Fiber Coloring Machine via the 4-40 screws on the recoater housing (see photo to the correct). Use a 3/32″ hex factor to secure the injector before use. To connect the PTRRRM for the recoater mold, tighten the connector at the conclusion of the green plastic tubing, then loosen by way of a 1/4 choose enable rotation.
The injector is equipped with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw with an internal plunger behaves as a syringe for that recoat material. To fill the syringe, point the lever downward (i.e., toward the recoat bottle), then rotate the knurled dispensing screw counterclockwise until it spins freely to fill the syringe (shown inside the photo off to the right). Then, to inject the recoat material into the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end of the travel range is reached. Avoid bottoming the dispenser because this may damage the internal plunger; also be mindful when re-engaging the threads in order to avoid cross threading the dispensing screw. Several fill/inject steps may be required until air is displaced in the system. Use lens tissue as well as an acetone or alcohol cleaning means to fix collect any excess recoat material that flows from your mold.
