METHOD AND TOOL FOR MANUFACTURING A PLASTIC CONTAINER, IN PARTICULAR A FUEL CONTAINER, BY MEANS OF INTERNAL PRESSURE FORMING
A method for manufacturing a plastic container by internal pressure forming including positioning a tubular preform between the die parts of a molding die having a die cavity; closing the molding die and forming or preforming a container from the preform using internal pressure, wherein a peripheral portion of the preform is pressed out of the die cavity through a die gap; laterally withdrawing the peripheral portion pressed out of the die cavity, as a result of which the container is divided into two container halves; and thermally separating plastic bridges and/or plastic threads which arise during the lateral withdrawal of the peripheral portion. Also disclosed is a molding die suitable for carrying out the method.
Method of Manufacturing a Plastic Canister
Disclosed is a method for manufacturing a container made of plastic, including the following steps: continuously extruding a hose, positioning an opened blow mold around the hose, so that the hose is arranged between the two blow mold halves, closing a hose gripper arranged at the blow mold to clamp the hose and simultaneously keeping the hose open at its upper side to form an inlet opening, separating the hose above the hose gripper to form the preform, horizontally moving the blow mold together with the preform hanging therein and held by the hose gripper into a blowing position, moving a blow mandrel assembly from above into the inlet opening of the preform, closing the blow mold halves, and inflating the preform in the blow mold to form a container.

Changing blow moulds in blow-moulding machines
A method for operating a forming device for forming plastic preforms into plastic containers, wherein in a working mode of the apparatus, the plastic preforms are transported by means of a plurality of forming stations along a predefined transport path, and by loading with a fluid medium are expanded into plastic containers, wherein to expand the plastic preforms, blow-moulding devices are used, inside which the plastic preforms are expanded into plastic containers, wherein in a change mode, at least one of the blow-moulding devices is removed from the apparatus and/or one of the blow-moulding devices is arranged on a blow-mould carrier of the apparatus, wherein to change the blow-moulding devices, a change device is used which has a gripper device for gripping the blow-moulding device. According to the invention, in a working mode, the forming device is operated in a first protected area which is not accessible to a machine operator, and the change device is arranged at least partially in a second protected area which is accessible for the machine operator for at least part of the time in working mode, wherein a connection can be created between the first protected area and the second protected area.

Mold, blow molding apparatus, and blow molding method
A mold includes a link member including a protruding grip forming part configured to form a grip part to a portion of a container by pressurizing a portion of a preform that is expanded during blow molding; and a piston member configured to move forward toward a cavity to thus press and rotate the link member. The grip forming part has: a pressurizing surface configured to pressurize the portion of the preform; and a contact surface configured to come into contact with the piston member, wherein the piston member has a pressing surface that comes into contact with the contact surface and presses the grip forming part toward an inside of the cavity when moving the pressurizing surface, and wherein the pressurizing surface is arranged at an opposite side of the contact surface of the grip forming part with respect to a moving direction of the piston member.
