CHROME / DUR
Needles with a normal chrome coating can be recognized by their shiny silver surface. The chrome coating provides protection against wear and corrosion. The surface is smooth and protects the material and the thread. Chrome needles can be used for all standard applications. Compared to nickel-plated needles, chrome-plated needles improve the service life of the needle at higher stitch counts.
At GROTZ-BECKERT, the comparable chrome coating is being gradually replaced by the more environmentally friendly “DUR” process. The technology used to apply this DUR chrome coating has undergone a fundamental overhaul. The new process is significantly more environmentally friendly and conserves resources. The dur™ technology provides even better wear protection—especially directly at the needle tip—as well as optimized sliding properties. Compared to conventionally chrome-plated needles, the DUR-coated needles appear slightly more matte (particularly visible on the needle piston).
