Fiber optic drawing frame

Drawing tower is an automatic control equipment which integrates light, machinery, electricity, gas. Through the drawing tower, under the protection of argon/helium atmosphere, the glass preform rod is heated & softened locally by heating furnace, and the fiber is drawn by roller drawing method.
