Abstract:
The invention is directed to a foamed injection moulded article comprising a foam composition obtained by foaming high density polyethylene having a quotient of melt strength and apparent viscosity > 2 cN/k.Pa.s wherein the melt strength is determined as described in ISO 16790:2005 and the apparent viscosity is determined as described in ISO 11443:2014.
Abstract:
A method of forming a printed structure (218) is disclosed. The method may include printing layers of a printed structure and incorporating an element (224) within the printed structure. The element may be removed in order to form tunnels within the printed structure. In some embodiments the element may be removed and reused in the formation of additional printed structures. The element may also be retained to form a composite printed structure.
Abstract:
Optical fiber cables (1001) comprising at least one optical fiber transmission medium (1006) and at least one elongated polymeric protective component (1002) surrounding at least a portion of the optical fiber transmission medium. The elongated polymeric protective component (1002) comprises a polymeric matrix material and a plurality of microcapillaries containing a polymeric microcapillary material, where the polymeric matrix material has a higher flexural modulus than the polymeric microcapillary material. Also disclosed are dies and methods for making such optical fiber cables and protective components.
Abstract:
A method for providing parts of waterproof and breathable shoes (20), parts of waterproof and breathable shoes (20) provided with the method, and waterproof and breathable soles (31) provided with the shoe parts (20). The method uses a mold (10a) of the type comprising a first element (11a) and a second element (12a), at least one of which has hollow regions (13a) of a matrix of impressions (14a), which are filled with polymeric material in the fluid state by depositing it in the hollow regions (13a) or by injecting it while the mold (10a) is closed. A support (17) made of flexible sheet is interposed between the first element (11a) and the second element (12a) and comprises a waterproof and breathable functional element (26), on which, when the mold (10a) is closed, the polymeric material sets and adheres to the support (17).
Abstract:
Disclosed are various embodiments for electrodes and sensors having nanowires. According to an embodiment as described, a dry sensor is provided. Nanowires, such as silver nanowires, are positioned within a polymer material, such as polydimethylsiloxane (PDMS) to form an electrode. A conductive element is attached to the electrode during its formation. Example conductive elements include, but are not limited to, a contact or a wire that may be communicatively coupled to medical equipment.
Abstract:
A consumable assembly (22) for use with an additive manufacturing system (10) to print three-dimensional parts (30), the consumable assembly (22) including a supply device (e.g., a spool (118)) and a filament (52) supported by the supply device, where the filament (52) has a composition comprising one or more elastomers and one or more reinforcing additives, and a filament geometry configured to be received by a liquefier assembly (44) of the additive manufacturing system (10). The composition is preferably configured to be thermally and/or chemically modified to reduce its flexural modulus.
Abstract:
A method of manufacturing a multi-layer golf ball includes injection molding a core from an ionomeric thermoplastic material such that the core has an outer surface with a plurality of polygonal land potions aligned on a common sphere and a plurality of grooves extending radially inward from the sphere. The core is then positioned between a first hemispherical shell and a diametrically opposed second hemispherical shell, which are each formed from a rubber material. The first and second hemispherical shells are then compression molded such that rubber material conforms to the outer surface of the core. The rubber material is then cured to form a unitary intermediate layer that surrounds the core. Finally, a cover layer is molded about the intermediate layer through one of injection molding and compression molding.
