Composite Manufacturing

Izumi International has been a part of the carbon fiber industry since its earliest days, so we understand the business inside and out. We’ve been supplying carbon fiber production equipment for more than 35 years, including creels, carbonization furnaces, sizing equipment, tension roll stands, and take-up winders. We also supply the downstream equipment for various composite manufacturing processes, including pre-preg and pultrusion creels, filament winder tensioners, re-winders and respoolers, weft feeders for carbon fiber weaving, fiber tension sensors, and more.

  1. Unisizer KS-7

    Unisizer KS-7

    The KS-7 was developed to size various fibers, spun yarns (cotton, silk, hemp yarns, etc) as well as a variety of filament yarns to prevent fuzz, improve strength and sustain elongation properties. Linking three processes (coating/sizing, drying, and winding) into one machine dramatically improves efficiency, quality, and contributes to saving space. The KS-7 is ideal for the recent trend of manufacturing a wide variety of fabrics in small lots, at minimum time, with frequent style change.
