The process for manufacturing barrels, developed with the aim of dimensional accuracy of the injection-moulded heads and blow-moulded barrel bodies, is characterised by the blow-moulding of double-barrel bodies from plastic and central splitting of the same into two barrel bodies, the injection-moulded production of bung-type heads from plastic, the cooling of the barrel bodies and of the bung-type heads to fitting form in cooling and calibrating sections downstream of the blow-moulding machine for producing the double-barrel bodies and the injection-moulding machine for the barrel heads, and the welding of the bung-type heads to the barrel bodies. …<??>The process for manufacturing wide-necked vessels provides for the blow-moulding of double-vessel bodies from plastic and central splitting of the same into two vessel bodies each having a border arranged at a distance below the vessel opening, the injection-moulded production of vessel lids from plastic, with an outer flange moulded onto the lower lid rim, the cooling of the vessel bodies and of the vessel lids to fitting form in cooling and calibrating sections downstream of the blow-moulding machine for producing the double-vessel bodies and the injection-moulding machine for the vessel lids, the injecting of a sealing compound of plastic into the lids and the setting of the lids onto the vessel bodies and closing of the lids with a clamping ring. …<IMAGE>… |
