Hoyleline Injection Mould Polishing (Ontario, Canada) offers its new CD and DVD optical mold polishing service for Canadian manufacturers in the multi-media industry. Lapping is a precision process or combination of processes used to provide flatness, parallelism, size and surface finishes to extremely demanding tolerances. The process is a manufacturing method that employs particles of an abrasive material to remove stock from a surface. It is comparable to sanding or grinding, except that sanding and grinding use abrasives that are fixed (bonded abrasives), whereas lapping employs abrasives, which are suspended in a liquid carrier, and freely move about. Hoyleline optical flat-lapping offers extreme flatness and defect-free surfaces. Optical flats along with a monochromatic light are used to measure flatness of molds in light bands, accurate to millionths of an inch. The company has more than 12 years experience professionally lapping optical finishes on CD, DVD and Petri dish mold inserts for the multi media and moldmaking industries. Their machines are capable of achieving 0-3 light bands of flatness, well within industry standards. No 'orange peel' and no 'edge roll-off'. Perfect for the finishing of CD, DVD, Petri dish moulds and many other applications.
