Production of non-spherical moulded glass and its device are disclosed. The procedure is carried out by raising temperature shape temperature T1 with normal pressure and mould core position as initial position, keeping temperature for 10-15 seconds, raising pressure to the first pressure P3, keeping pressure for 5 seconds, releasing mould core, raising pressure to shape pressure P1, keeping temperature and pressure for 45 seconds at shape temperature, lowering pressure to cooling pressure P4, cooling for 15 seconds, and lowering temperature to cool temperature T3 with mould core increase. The apparatus consists of thermal feedback system, cooling system and pressure system. It can develop non-spherical lens surface Ra value and reach to nanometer precision.
