Abstract (en)
[origin: WO2012087227A1] A method for producing and coating a specific surface of moulded plastic object, comprising the steps of: a) producing said object in a manufacturing machine according to per se known methods; b) transferring said object into and through a tunnel comprising at least three, optionally four or five consecutive partially separated chambers in the direction A to E, where chambers A and E each comprise an opening to the surroundings, the consecutive chambers of the tunnel having a controlled atmosphere obtained by injection, said injection of controlled atmosphere being set up in such a way that the net air transport in said tunnel is directed from chamber D to A and out to the surroundings as well as from chamber E and out to the surroundings, during which transferring the object receives a treatment comprising: applying, in chamber A, a microemulsion comprising a cleaning agent to said specific surface; rinsing, in chamber B, said specific surface with a volatile rinsing agent capable of removing said microemulsion from said specific surface; optionally drying, in optional chamber C, in such a way that said volatile rinsing agent is removed from said specific surface; and optionally adjusting, in optional chamber D, the temperature of said specific surface to the temperature of subsequent coating step; and c) transferring said moulded plastic object from any of chambers B -D to chamber E and coating said specific surface according to per se known methods.
