摘要

Moulded optical part (1) having a back (5) and a front surface for a head-up display, said part comprising a rotational axis bearing or bearings (2, 3) integrally formed in the back surface for rotation of the part; and a motor and spring support or supports (4) integrally formed in the back surface for rotating the part; the front surface having a mirror coating. In particular, the mirror coating is a metalized coating, obtained by physical vapour deposition of aluminium. The optical part can be an injection-compression moulded part, in particular of a thermoplastic material, namely polyetherimide - PEI. A method of producing the moulded part comprises moulding heated material in a mould for forming said part with said bearings and supports in the back surface, and coating the front surface with the mirror coating, wherein the moulding and coating steps may be carried out in a clean room environment.
