POLYMER COMPOSITIONS, ARTICLES MADE FROM SUCH COMPOSITIONS AND METHODS FOR MOLDING SUCH COMPOSITIONS
A polymer composition comprises a thermoplastic polymer, a polymer additive selected from the group consisting of nucleating agents, clarifying agents, and combinations thereof, and a fluoropolymer. A molded article comprises at least one wall defining a cavity, the wall having an opening therein permitting access to the cavity. The wall comprises a polymer composition comprising a thermoplastic polymer, a polymer additive selected from the group consisting of nucleating agents, clarifying agents, and combinations thereof, and a fluoropolymer. A method for molding a polymer composition is also provided.
Methods, assemblies, and systems for handling blow-molded containers
Method to manufacture at least one container includes disposing at least one parison within a mold assembly having at least one mold chamber defined therein, wherein at least a first portion of the at least one parison extends outside the mold assembly and at least a second portion of the at least one parison is disposed within the at least one mold chamber. With the mold assembly closed, the second portion of the at least one parison can be blow-molded to form at least one container body. The first portion of the at least one parison can be gripped with a gripper when the mold assembly is opened, and a stabilization member can be extended proximate to the gripper to engage a surface of the at least one container body. Gripping assemblies and systems are also provided.

METHOD OF MANAGING PREFORMS IMMOBILIZED IN A HEATING STATION
The invention concerns a method for managing captive preforms immobilized in a heating station during an interruption of production, the preforms following a production stream, the heating station including a device for conveying preforms and a heating cavity bordered by at least one row of emitters of monochromatic electromagnetic radiation. The method consists in ejecting from the production stream the cold captive preforms that have been immobilized before they have been exposed to the electromagnetic radiation emitted by the emitters to a recycling stream and rejecting from the production stream the hot captive preforms that have been at least partly exposed to the electromagnetic radiation emitted by the emitters to a reject stream separate from the recycling stream.

PINCH-FORMED BLOW MOLDED BRACKET OFF THE PARTING LINE
Blow molded plastic components are disclosed having integrally formed brackets, formed together with the component in the molding step. A method of blow molding is disclosed for integrally forming brackets onto a blow molded component. More specifically, the disclosures relates to a blow molded plastic component having a bracket formed integrally in the blow molding process and configured to rotate onto and lockably engage undercut features or lugs formed integrally on the outer surface of the blow molded component, all features formed during the molding process.

MOLDING SYSTEM AND METHOD FOR MANUFACTURING MODULAR INTERLOCKING ARTICLES
Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

Device for producing container products from plastics material
A device produces at least one container product made of plastics material, which is molded by a molding device (1). The container product is filled with a predefinable container content by a filling device and closed by a closing device. The finished container product is fed to a post-treatment zone in which the container product and/or the respective container content is subjected to a temperature-influencing effect.
