模內(nèi)澆口分離自動化，降低對人的依賴度；傳統(tǒng)的塑膠模具開模后產(chǎn)品與澆口相連，需二道工序進行人工剪切分離，模內(nèi)熱切模具將澆口分離提前至開模前，消除后續(xù)工序，有利于生產(chǎn)自動化，降低對人的依賴。

Spun fiber：

Rotating glass preform during fiber drawing process produces a waveguide with unique properties: all fiber non-uniformities are averagedalong all possible directions, effectively cancelling out total fiber birefringence. With total (but not local) birefringence close to zero, weobtain a fiber that will hold circular polarization (even when bent or twisted). Unlike conventional PM fibers that can hold only linearly polarizedlight, or annealed fiber that requires special handling, this low-birefringence fiber preserves both linear and circular polarization andcan relay it with minimum error over large distances.Highly-birefringent preforms with incorporated stress produce spun fibers that can withstａnd significant bending and twisting and hold polarizationover large number of coils with reasonable accuracy (without costly annealing process). Polarization accuracy in this case dependson local (instant) birefringence that introduces a small constant error, independent of fiber length.Elliptical core fiberOur elliptical-core PME1300-10 fiber provides high polarization extinction and insensitivity to bending and twisting stress. Unlike conventionalPM fibers, birefringence of the elliptical-core waveguide has low thermal dependence (10 times lower than Panda).Due to core geometry the splice losses to a conventional circular-core fiber (SMF, Panda or Bow-tie) are asymmetrical - 0.5 dB for circular-toellipticalcoupling and 2.5 dB for elliptical-to-circular arrangement.
