A method for temperature conditioning thermoplastic preforms for blow molding. The preforms are guided along a chain path in a transport direction by a plurality of transport and handling means through a heating apparatus. In a heating section, the plurality of heating devices are arranged one after another in the transport direction. On at least one side opposite the heating devices, counter-reflectors are provided, which together with heating devices, form a tunnel-like heating area through which the preforms are transported. In an area of the heating section, a concurrently moving counter-reflector is assigned to each perform or each transport and handling means. The counter-reflectors are guided on a circulating reflector path separate from the chain path, which in the area of the heating section runs parallel to the chain path and in at least one area outside the heating section takes a path route deviating from the chain path.

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

A blow molding apparatus improves productivity and obtains a high-quality molded product by supplying a good-quality parison to molds. A blow molding apparatus includes: a die head which discharges a parison; a parison supplying part which cuts the discharged parison at a preset length and conveys the cut parison; and a blow molding part in which the supplied parison is clamped between blow molds so as to perform blow molding. The parison supplying part has a pickup chuck which conveys the cut parison alternately to a first supplying position set on one of right and left sides with respect to a discharge center of the die head and a second supplying position set on the other of right and left sides with respect to the discharge center. The blow molding part performs blow molding at the blow molds arranged at the first supplying position and the second supplying position, respectively.

A hollow container manufacturing method comprises: an injection molding step of forming a preform having a neck portion and a barrel portion, at least a part of the barrel portion being solid, by injection molding; an intermediate product formation step of inserting a boring rod 134 from the neck portion side into the barrel portion 23 to form a space part of at least a predetermined depth in the barrel portion, thereby converting the preform into an intermediate molded product; and a final blow molding step of blow-molding the intermediate molded product within a final blow mold to form a hollow container which is a final molded product.

A blow molding machine for blow molding a container having an integrally formed handle; said container blow molded from a previously injection molded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

A container treatment system (1, 13) that has at least two working areas (AP). Each of the working areas (AP) respectively comprises at least one exchangeable working tool (2) and/or one adaptable format part. Furthermore, the container treatment system (1, 13) comprises at least one automatic exchange machine (10) which is movable, in particular drivable, to the at least two working areas (AP), which automatic exchange machine (10) can be connected selectively to any of the respective working areas (AP), in particular using centering means (22, 32), and which automatic exchange machine (10) comprises tools for exchanging the working tools (2) and/or for adapting the format parts of the respective working area (AP). The invention further relates to an automatic exchange machine (10) for exchanging working tools (2) and/or for adapting the format parts of at least two different working areas (AP) of a container treatment system (1, 13).

A device and a method for producing a preform having a shoulder and base geometry optimized for subsequent stretch blow molding, since the preform cannot be produced according to the conventional injection-molding method. For this purpose, the preform produced in the injection-molding tool is transferred into a conditioning station and is conditioned and cooled in the shaft while no contact is made with the top of the preform and the preform shoulder on account of a special contour of the conditioning receptacle. Due to the reheating of these preform regions they can be mechanically deformed into a new geometry which is advantageous for the blow molding process and thus their wall thickness can also be influenced. In the subsequent blow molding process the deformed preform has the advantage that the plastic material which is distributed better in the bottle results in considerable material savings and higher quality bottles.

A method of manufacturing a foam molded article, comprising: an extrusion step of extruding a molten, kneaded resin containing a foaming agent through an annular slit between a die core and a die shell surrounding the die core to form a cylindrical foam parison and extruding the foam parison between a pair of split molds; a lower-pinching step of pinching the foam parison between lower pinchers disposed under the split molds; and a molding step of molding the foam parison by closing the split molds, after the lower-pinching step, wherein H/D is 1.33 to 3.33 and L/D is 0.33 to 2.00 where D represents a diameter of the die core; H represents a distance between a lower surface of the die core and an upper surface of each of the split molds; and L represents a distance between a lower surface of each of the split molds and an upper surface of the corresponding lower pincher, is provided.
