The Protool Plastics Group use diamond turned and nickel plated cavity inserts to produce optically clear mouldings in PMMA and PC.
Due to the complex form structure of the lens EDM and polishing processes are not possible.
Diamond turning not only ensures amazing dimensional accuracy but also a high gloss finish ready for a flash of electro-formed nickel to give the SPI-A1 finish.
The insert is shown post turning but before the application of the bright Nickel finish.
