Design and manufacturing of spinning nozzles for synthetic fibers, developed through years of advanced technology
Spinning nozzles are a key technology in the production of synthetic fibers. Our advanced technology and superior production equipment have allowed us to produce high-precision, high-quality spinning nozzles for synthetic fibers for over half a century. They support the quality of all Toray's synthetic-fiber products.
Applications
- Nozzles for spinning macromolecule (polymer) materials
A required part of manufacturing synthetic fibers
Features
- Our nozzle design and production takes advantage of the performance, viscosity, and other features of the polymers used to form synthetic fibers.
- In addition to circular, we support a wide range of hole shapes.
- We provide designs to meet customer requests, including hollow-fiber and texture-specific forms.
- Mirror and lacquer-style surface finishing available on request.
- Toray Precision nozzles are used in all of Toray’s fiber production.
