Non-standard /turned seals are produced by machining the desired seal profile out of a prefabricated tube made from specially assorted material. This is done on special CNC lathes equipped with software for and tooling for seal manufacturing.
The turning process makes it possible to manufacture a small series or even a single seal in a very short time.
Turned seals are very useful when there is a need to quickly replace a damaged seal that is causing a shutdown or a machine critical to the manufacturing process.
Because each production run has to be individually prepared – unit cost of turned seals is higher than of standard seals. Nonetheless machining seals is often more economical. This especially when small quantities are needed i.e. at the design stages or in new product pilot runs.
Turned seals have similar characteristics to standard seals. They are made from the same type of materials as standard seals in large production volumes. It is always advisable for you to contact us to help you with material selection prior to placing an order with us.
