This Secondary Coating Line is ideal for operator skill independent use within production and laboratory settings. Two basic model configurations allow the user to pick between a setup for standard linear proof testing with additional mandrels for rotary high strength testing.
The linear version is ideal for production proof testing with forces up to 22 N. Motorized clamps with carefully designed rubber inserts ensure that the fiber coating is not damaged within the testing process while at the same time eliminating the necessity for an outside air supply. Amounts of pulling force, pulling speed and hold time are programmable and conveniently accessible to the operator from the built-in LCD touch-screen control. Data from tests could be saved and accessed using the USB port or Ethernet interface.
Mandrels the exact same design as with NYFORS’ optical fiber recoaters can easily be mounted on the proof tester within the rotary high strength configuration. The fiber is wrapped round the two mandrels which support it using a special clamping mechanism. This way much higher loads does apply onto the fiber, enabling breaking strength tests under controlled circumstances.
Adjustable clamp positioning facilitates testing with all the highest force levels as well as testing of short fiber lengths. The compact and light weight design definitely makes the instrument easy to maneuver in a laboratory environment and to integrate in a production work bench where space reaches a premium. The device is actually a compact and light-weight instrument suitable for testing the effectiveness of optical fibers as much as 30 N. The equipment is created to meet all types of applications when a strength test has to be performed.
The device was created with the user in mind. The fiber is readily put into the guided linear clamps, as well as the testing starts automatically having a “One Touch” go button. The built in microprocessor controls all of the important parameters such as pulling force, pulling speed and hold time. This permits for any completely controlled test each time.
The Fiber Drawing Machine can be connected to an external PC, which enables use of all programmable parameters and settings. The device is adapted to stand-alone use or to the integration into different subsystems. The device has an extensive ability of logging and saving information including pulling force, pulling speed and fiber diameter along with other parameters.
Two recoat injector configurations can be found. The PTR307 uses an automated pump to inject the recoat material. The volume 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 replacement injector for the PTR307B recoater is accessible below. Please be aware the automatic injector is simply appropriate for high-index recoat material, whilst the manual injector is compatible with both low- and- index recoat material; they are both sold separately below. Please contact Tech Support to learn more.
he manual injector could be mounted to compatible SZ Stranding Line through the 4-40 screws on the recoater housing (see photo to the correct). Utilize a 3/32″ hex factor to secure the injector before use. For connecting the PTRRRM towards the recoater mold, tighten the connector after the green plastic tubing, then loosen by way of a 1/4 turn to allow for rotation.
The injector is equipped with a distribution valve as well as 2-position selection lever for directing the flow of recoat material. A knurled dispensing screw with the internal plunger acts as a syringe for your 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 within the photo to the correct). Then, to inject the recoat material in to the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until close to the end of the travel range is reached. Avoid bottoming out your dispenser since this may damage the internal plunger; also be mindful when re-engaging the threads to prevent cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced in the system. Use lens tissue as well as an acetone or alcohol cleaning solution to collect any excess recoat material that flows from the mold.
