Spinning rings

CrC-coated spinning rings achieve higher speeds and provide for better yarn quality than hard chrome-plated or nitrided rings.

Advantages: higher spinning speeds and reduced hairiness than with conventional surface technologies.

Opening cylinders of spinning machines

BALINIT CNI (CrN)-coated opening cylinders outperform those with Ni-diamond coatings in polyester and cotton yarn spinning applications.

Advantages: higher service life than with Ni-diamond coatings.
