STOCKHOLM, Feb. 21, 2013 — Nyfors Teknologi AB has introduced the AutoCoater 2 for automatic optical fiber recoating in laboratory and production environments. The system provides the flexibility of proprietary silicone mold technology while maintaining the productivity of an operator skill-independent, fully automatic process.
The combination of easily exchangeable silicone recoating molds and a removable injection system makes it easy to set up, optimize and rapidly reconfigure for different recoating applications and requirements. With different mold types and diameters available, the operator can choose whether to create a uniform diameter recoating that matches the original fiber diameter, recoating with a cross section slightly smaller than the original fiber coating, or recoating with a larger diameter that overlaps the original coating at each end of the recoat area.
Molds are easily interchangeable in a few seconds with no realignment required. The customer-selected recoating compound is automatically injected into the mold from an easily attached 1-oz Nalgene bottle, functioning as the recoater reservoir tank. The bottle and injection pump, supply lines and injection needle may be removed and exchanged as a single unit in <1 min, eliminating the need to purge or cleanse the injection pump and supply lines when changing from one type of recoating resin to another.
Short curing times on the order of ≤3 s are achieved through an efficient curing system that processes standard high- and low-index recoating materials, resulting in cycle times of 15 s or less.
Two different model configurations allow the customer to choose between linear and rotary high-strength tensile testing. Motorized clamps eliminate the need for an external air supply, while LCD touch-screen control gives the operator easy access to all system parameters.
