COLLAPSIBLE POLYTHENE TUBES
Production capacity/annum 7.2 Million Tubes.
Production process
HDPE granules are fed to the hopper. The plasticised stock is transferred to nozzle head. The amount of plastic required for tube is (hen injected through a ring nozzle against the injection mould holding tube head and thread mould. The injection mould with the formed tube head then moves upward and so draws a Parison with uniform wall thickness of plastic melt fed from ring nozzle. This Parison is then blown into water-cooled mould, the inner surface of which corresponds to the desired finished shape of the tube. A gripper device lakes the cooled tubes out of the mould and they are fed by a tripper to a cutting unit where their bottom portion is trimmed to size. These tubes then go to rotating mandrels lor 3-colour printing, they are then lacquered and dried by hot air.
