Fiber Coloring Machine – You Will Want To Consider This..

This automatic optical fiber tensile testing system is made for operator skill independent use in production and laboratory options. Two basic model configurations allow the user to choose between a set up for standard linear proof testing along with additional mandrels for rotary high strength testing.

The linear version is ideal for production proof testing with forces as much as 22 N. Motorized clamps with carefully designed rubber inserts ensure that the optical fiber coloring machine is not damaged within the testing process while at the same time eliminating the need for an outside air supply. Degrees of pulling force, pulling speed and hold time are programmable and conveniently available to the operator through the built-in LCD touch screen control. Data from tests can be saved and accessed via the USB port or Ethernet interface.

Mandrels of the identical design as in NYFORS’ optical fiber recoaters could be mounted on the proof tester inside the rotary high strength configuration. The fiber is wrapped around the two mandrels which support it using a special clamping mechanism. This way higher loads can be applied onto the fiber, enabling breaking strength tests under controlled circumstances.

Adjustable clamp positioning facilitates testing with all the highest force levels along with testing of short fiber lengths. The compact and lightweight weight design makes the instrument easy to move around in a laboratory environment and also to integrate in a production work bench where space are at a premium. The equipment is actually a compact and light-weight instrument suitable for testing the potency of optical fibers as much as 30 N. The device is created to meet all kinds of applications in which a strength test needs to be performed.

The equipment was created with all the user under consideration. The Fiber drawing machine is definitely positioned in the guided linear clamps, and also the testing starts automatically with a “One Touch” go button. The built in microprocessor controls all the important parameters like pulling force, pulling speed and hold time. This allows for a completely controlled test each time.

The device can be linked to an outside PC, which enables access to all programmable parameters and settings. The equipment is adapted to face-alone use or to the integration into different subsystems. The device comes with an extensive capability 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 quantity of material dispensed through the automatic injector is controlled by hand via the top-mounted “Inject” button or programmed to the machine using the tablet controller. The PTR307B includes a manual recoat injection system that needs the consumer to manually dispense the recoat material to the mold cavity; a substitute injector for the PTR307B recoater is available below. Please be aware uojthk the automatic injector is simply compatible with high-index recoat material, whilst the manual injector works 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 fiber recoaters using the 4-40 screws on the recoater housing (see photo off to the right). Use a 3/32″ hex factor to secure the injector just before use. To connect the PTRRRM towards the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen with a 1/4 turn to enable rotation.

The injector comes with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw having an 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 right). Then, to inject the Secondary coating line, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until nearby the end from the travel range is reached. Avoid bottoming the dispenser as this may damage the internal plunger; also take care when re-engaging the threads to prevent 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 answer to collect any excess recoat material that flows from the mold.
