HY series thermal drawing rolls and thermal drawing machine

Description

HY series thermal drawing rolls can be used in the FDY spinning for PP, PET, PA6, PA66 filament, and in the thermal drawing for HSHMPE fibers.

Thermal drawing rolls have two kinds of surface: ceramic and hard plating.

Thermal drawing machines have a variety of models, with 5 rollers, 6 rollers, 7 rollers, or 9 rollers. The diameter of thermal drawing rollers ranges from φ220 mm to φ360 mm, and length from 400 mm to 1200 mm. A unique heating technique is applied to achieve temperature uniformity and reduce energy consumption.
