METHOD FOR WELDING A HEAT SHIELD DURING MANUFACTURING OF A VEHICLE COMPONENT

A method for welding a heat shield during manufacturing of a vehicle component made from a thermoplastic material. The heat shield includes: a reinforcement layer made from a thermoplastic material which is weldable to the thermoplastic material of the vehicle component; and a heat shielding material that differs from the thermoplastic material of the reinforcement layer and is configured to decrease transfer of heat through the reinforcement layer to the vehicle component. The method includes: heating the heat shield to bring the thermoplastic material of the reinforcement layer in a molten state; placing the heated heat shield in a mold; bringing into the mold the thermoplastic material of the vehicle component in a molten state; welding the thermoplastic material of the reinforcement layer being in a molten state to the thermoplastic material of the vehicle component being in a molten state, by blow molding the vehicle component in the mold.

Composite container, inner label and plastic member

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A method for producing a plastic tank includes preparing a tank wall as a hot extrudate. A reinforcing sheet is then attached to at least one region of the outer layer of the hot extrudate. After introducing the attached reinforcing sheet and the hot extrudate into a shaping tool, the shaping tool performs shaping of the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.

Method and apparatus for producing a filled SBM bottle

A method for producing a sterilized container comprises: providing a preform having a hanger arranged on a bottom of the preform, heating the preform in a heating device, feeding the heated preform into a stretching and blowing apparatus, stretching and blowing the preform in the stretching and blowing apparatus such that the container for the infusion solution is formed from the preform, cleaning the formed container in a rinsing apparatus, and drying the cleaned container in a drying device, filling the cleaned and dried container at least with an infusion solution, via a filling opening present in the container, in a filling plant, closing the container by attaching a closure cap to the filling opening of the container, sterilizing the closed container in an autoclave, wherein the hanger of the preform is oriented and folded over by a bending apparatus prior to stretching and blowing in the stretching and blowing apparatus.

11724432 · 2023-08-15 ·

A transparent plastic integrally molded goblet has a cup-shaped part, a columnar first leg and a disc-shaped first base integrally molded from transparent plastics. The bottom edge of the cup-shaped part extends downwards to form the first leg. The bottom end of the first leg integrally forms the first base. The cup-shaped part has a circumferential wall which encloses the circumference of a first space. The top edge of the circumferential wall forms an annular first ring frame, and the central part of bottom edge of the first base downwards forms a first convex pin. The integral molding of transparent plastics can enhance the appearance integrity of the goblet, the manufacture of the goblet is easy and the product yield is increased.

HOLLOW BODY MOLDING AID AND MOLDING METHOD

The hollow body molding aid includes a body, a connector, a first profiling assembly, a second profiling assembly, and a positioning mechanism. The connector is fixedly connected to the body. The first profiling assembly is fixedly disposed on one side of the body and is configured to position one half of a reinforced housing. The second profiling assembly is fixedly disposed on the other side of the body and is configured to position the other half of the reinforced housing. The positioning mechanism is disposed on the first profiling assembly and the second profiling assembly. The reinforced housing can be positioned, thus guaranteeing molding quality of the reinforced housing and blanks. In addition, the reinforced housing can be accurately positioned in a cavity of a mold through a manipulator, without the need to use a plurality of air cylinders for step-by-step driving.

BLOW MOLDING METHOD, COMPOSITE PREFORM, COMPOSITE CONTAINER, INNER LABEL MEMBER, AND PLASTIC MEMBER

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

Method for forming a welding spout on a parison during the blowing of a tank

The invention relates to a tank of plastics material produced by blow-molding of a parison, incorporating a welding spout, of a shape projecting from its outer surface which has an edge configured to be welded to a corresponding edge of an attached part, the welding spout ending axially, on an inside of the tank, in a shape resulting from contact molding between the parison and a molding component, in which the welding spout ends axially on an outside of the tank in a shape resulting from contact molding between the parison and a molding component.

Plastics pipeline with a support sleeve

The invention relates to a plastics pipeline comprising at least one pipeline end (1) and at least one support ring (2). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring (2) remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section (1) runs through the support ring (2) and, as viewed radially, is pressed from the inside outward against the support ring (2), wherein the pipe section (1) engages around the support ring (2), such that the support ring (2), with its outer surface, and the pipe section (1), with its outer surface, are substantially in alignment.
