Fumbling for the belt buckle in the dark? This isn’t necessary for the Audi seatbelt buckle. A housing cover with an integrated diffuser panel indicates the direction for the belt. It‘s produced at KH using a twin-turn-Tool which rotates on both sides.
First of all, light diffusing PC streams into the cavity where it forms the light duct. Then the small rotary plate which has been integrated at the fixed side of the tool rotates with the newly injection-molded diffuser panel so that black PC-ABS can be applied on the nozzle side forming the inner part. Thereafter the part is transferred to the movable side and the rotary disc of the machine transfers it to the third stage in which the outer contour is produced.
