Blow molding of thermoplastic parison or preforms to produce pressure resistant containers involves inclusion of a net reinforcement and connector fittings in the wall during molding

摘要

A reinforcing and stabilizing net (50) is integrated into a container wall during manufacture by blow molding process. A reinforcing and stabilizing net (50) is integrated into the container wall during container manufacture. In a blow molding process connectors (1) are incorporated in the container wall by: a) insertion of a blowing tube (4) into a molding tool (5) to position a counter ring (71) opposite a connector rosette (10) on a moving mandrel (11); b) feeding a hot plastic parison (14) into the tool and inflating; c) forward movement of the mandrel to clamp the parison between connector rosette and counter ring; and d) retracting the mandrel with the inflating container. Containers may also be produced from preforms with premolded connectors.
