Surface treatment

coated and uncoated acupuncture needles

Traditionally, acupuncture needles were always uncoated, the raw steel wire might have been polished, but it did not undergo any further treatment. Optimal puncture characteristics were and still are determined by a precisely ground tip and the surface texture of the steel wire.

Since the 1970s, acupuncture needles have been coated with high-quality silicone compounds especially approved for medical use. This silicone coating has also been used for years on cannula needles. The coating significantly improves puncture characteristics. In Western countries, this feature has significantly increased the acceptance of acupuncture as a treatment method.
