Edgewise wikkelen – nu ook mét kern

May 27, 2023

Bij het edgewise wikkelen wordt de wikkeling van de spoel loodrecht op de as van de spoel gewikkeld, in tegenstelling tot de meer traditionele axiale wikkelmethode waarbij de wikkeling parallel aan de as wordt geplaatst. Het kiezen voor een edgewise spoel hangt af van de specifieke vereisten en behoeften van de toepassing.

Smooth outsourcing for handpiece for eye surgery

January 4, 2022

Sometimes it is quite human reasons that trigger a search for a supplier. At Bürki inno med AG from Widnau (Switzerland), the retirement of an employee prompted the search for a coil supplier with proven medical technology experience. Until then, the developer and manufacturer of microsurgical instruments for ophthalmology had wound its own coils by hand. Within a few months, production was then transferred to KUK Group, the world’s leading manufacturer of customised coils and electronics. “This is an enormous relief for us. The process stability could be improved and the testing effort considerably reduced,” says Martin Bürki, founder and partner of Bürki inno med. KUK produces a wound coil for the medical technology manufacturer, which is cast in the housing. It is used to drive a handpiece for eye surgery. Read more
