A method of blow-molding synthetic resin articles in which an image of an actual article is produced by blow-molding is displayed. A wall thickness control curve on a display screen of a computer controlling the blow-molding machine and critical locations of the curve are graphically reproduced on the image of the article.

Method of production blow-molded synthetic resin articles

A molding apparatus has a pair of mold halves having faces engageable together to form a nonstraight passage having an intake end and an output end, extruder means for forming a hollow plastic preform and feeding it to the intake end of the passage, pump means connected to the output end of the passage for drawing gas therefrom and thereby applying drawing the preform through the passage, and a seal carried on one of the faces, extending along the passage, and engaging the other of the faces for preventing gas flow between the faces into the passage when the mold halves are closed together.

Mold for suction/blowing system

A blow molding machine for producing three-dimensional low-waste articles including at least one horizontally separated blow mold formed of upper and lower half-molds, a device for vertically displacing at least one of the upper and lower half-molds between an open mold position in which the upper half-mold is spaced from the lower half-mold, and a closed mold position in which the upper and lower half-molds engage each other, a device for locking the upper and lower half-molds in the closed position, and a device for pivoting the upper half-mold in the open mold position about a horizontal axis by substantially 90&deg; and/or displacing the upper half mold in a horizontal plane.

Blow molding machine for low-waste blow molding

A method of manufacturing hollow bodies including inserting into spaced mold halves of a blow mold of a blow molding machine plastic hose-shaped blanks at an extrusion station of the blow molding machine and closing the blow mold, displacing the closed blow mold from the extrusion station to a calibration station of the blow molding machine, inserting thereat blow mandrels into respective cavities of the closed blow mold, lifting, after expiration of predetermined blow time, the blow mandrels, together with the blown hollow bodies to an intermediate position and removing the blown hollow bodies from the blow mandrels lifting the blow mandrels to their initial position thereof, and displacing the blow mold from the calibration station to the extrusion station, with the displacing of the blow mold between the extrusion station and the calibration station being effected by displacing the blow mold at a right angle to a connection line of arranged side-by-side cavities of the blow mold.

A barrel of thermoplastic material has at least one connecting portion having an emptying opening and arranged in a trough-like depression in the upper end part of the barrel. In the region of the connecting portion the barrel has at least one inclined surface which extends between the upper end part of the barrel and the side wall of the barrel. The inclined surface is of such a configuration that in a barrel emptying position the emptying opening forms the lowest part of the interior of the barrel to permit at least almost complete emptying of the barrel.
