The present disclosure provides a pellet. In an embodiment, the pellet includes a body having a first end and an opposing second end. The body is composed of a polymeric material. The body has a length and a diameter (body diameter). A channel having a diameter (channel diameter), extends through the body from the first end to the second end. The pellet has a channel diameter-to-body diameter ratio from 0.05 to 0.45. The present disclosure also provides a process for soaking the pellet in a liquid additive and forming a loaded pellet with the additive in the pellet body.

Hollow pellets and methods of soaking

An apparatus comprising: (a) a mandrel; (b) an internal guide spaced apart from the mandrel; (c) an external guide extending around all or a portion of the internal guide and being spaced apart from the mandrel; wherein a pipe extends between the internal guide and the external guide and then over the mandrel so that the mandrel changes one or more dimensions of the pipe.

Mandrel and support assembly

The present disclosure provides a die assembly for producing a microcapillary film. The die assembly includes a first die plate, a second die plate, a plurality of multi-jackbolt tensioners connecting the first die plate to the second die plate, a manifold, and a plurality of nozzles. The manifold is located between the pair of die plates and defines a plurality of film channels therebetween. The plurality of film channels converge into an elongate outlet, wherein a thermoplastic material is extrudable through the plurality of film channels and the elongate outlet to form a microcapillary film. The plurality of nozzles are located between the plurality of film channels. The plurality of nozzles are operatively connected to a source of channel fluid for emitting the channel fluid between layers of the microcapillary film, whereby a plurality of microcapillary channels are formed in the microcapillary film.

Die assembly for producing a film

A forming and trimming tool () operable to form and trim a composite material part. The tool includes a lower die (), a core () mounted to the lower die, at least one lower pressure pad () mounted to the lower die, and a cutter () mounted to the lower die. Additionally, the tool includes an upper die (), a cavity mounted to the upper die, and at least one upper pressure pad () mounted to the upper die.

Forming tool with integral cutting for composite material

The present invention thus provides a fabric-laminated plastic part and a novel process where the fabric edges are covered with a second plastic component that adheres both to the fabric and to the first plastic material. A first plastic substrate component is prepared with an adhered fabric surface area and then the edges of the fabric are overlapped by a second molded-on, plastic edge-covering component. The second material covers the fabric edge to provide an aesthetically pleasing surface. This construction produces a more durable fabric edge covering and eliminates the tendency of the fabric to peel off the molded part during use.

Molded parts with fabric surface areas and processes for their production

A protective enclosure is disclosed that provides protection and energy management for a sensitive or fragile part or device that can be enclosed. The enclosure comprises one or more rigid structural components and one or more soft touch surface components from which one or more ribs originate and pass through the rigid structural component(s) to provide the energy management for the part or device when it is enclosed. The soft touch surface and rib material can be a low modulus, plastic material such as a thermoplastic elastomer and can optionally be foamed to provide further softness for the soft touch surface effect and/or for the energy management needs in the pass through ribs. Thermoplastic polyurethane (TPU) is a particularly suitable thermoplastic. It has also been found that the protective enclosure can be designed to utilize the soft touch component to provide a substantially continuous liquid and dust resistant seal for any moveable or removable structural components. Preferably the pass through ribs and the soft touch surface are molded onto the first rigid component(s) by molding them onto the first component using a two shot molding, insert molding or overmolding process.
