A composite thermoplastic film and the manufacturing method are provided in the present invention. The method includes: providing a first structural layer and a second structural layer; performing a co-extrusion step to form a composite layer, in which to use a first extruding machine to perform the co-extrusion step, so the first structural layer is divided into a first thermal fuse film and a third thermal fuse film, and use a second extruding machine to perform the co-extrusion step, so the second structural layer is formed as a second thermal fuse film and disposed between the first thermal fuse film and the third thermal fuse film to form a composite layer; and performing a film-forming step, the composite layer is cooled to form a film through a forming wheel, and a rotating speed of the forming wheel can be controlled to acquire a desired thickness of the composite thermoplastic film.

It is provided an extruder for a system for the additive manufacture of freely formable metal parts with or without a supporting structure by means of an extrusion method from a composite material, which is arranged on a three-dimensionally movable kinematic mechanism, with a building platform. The extruder consists of a housing and a screw arranged in the housing. The extruder is provided with a mechanical drive for the composite material to be extruded, with an exchangeable nozzle, arranged on the housing, and the housing is connected to the mechanical drive by way of suitable means for transporting the composite material.

An optical fiber cable includes: a core including optical fibers; a reinforcing wrap that surrounds the core; and a sheath that accommodates the core and the reinforcing wrap. The reinforcing wrap includes an overlapping portion. A first end portion of the reinforcing wrap overlaps a second end portion of the reinforcing wrap at a portion of the reinforcing wrap in a circumferential direction of the optical fiber cable in a cross-sectional view.

The present invention relates to thermoplastic polyurethanes obtainable or obtained by reacting at least a polyisocyanate composition comprising at least one polyisocyanate, at least one chain extender, and at least one polyol composition, wherein the polyol composition comprises at least one polyester polyol (P1) which is obtainable by reacting an aliphatic dicarboxylic acid having 2 to 12 carbon atoms and a mixture (M1) comprising propane-1,3-diol and a further diol (D1) having 2 to 12 carbon atoms, preferably butane-1,4-diol. The present invention also relates to a preparation process for such thermoplastic polyurethanes and also to the use of a thermoplastic polyurethane according to the invention or of a thermoplastic polyurethane obtainable or obtained by a process according to the invention for the production of extrusion products, films and shaped bodies or for the production of polymer compositions.

An active grille shutter arrangement having an assembled modular frame with a plurality of primary frame pieces formed by extrusion. Each one of the plurality of primary frame pieces has a first end, a second end and at least one key slot extending between the first end and the second end. Each of the plurality of frame pieces also includes a hollow bore extending through the each one of the plurality of primary frame pieces forming an aperture at the first end and an aperture at the second end. When the modular frame is assembled there is an upper frame portion and lower frame portion, both formed from one of the plurality of primary frame pieces. The arrangement also includes a number of alternate frame and vane pieces that allow several different active grille shapes and configurations to be formed.

Disclosed are systems and methods for manufacturing compression collars for reinforcing sealed connections between a length of piping and a plumbing fitting. Specifically, compression collars and related methods of making include extruding a hollow tube having one or more ridges which are then partially removed or trimmed to provide positioning tabs on one end of the compression collar. The compression collars can be cut to the desired length from the extruded hollow tube. In this way, compression collars with features for enhancing the strength and reliability of an interference fit, as well as their ease of use, can be manufactured rapidly with little material waste through modifications to the extrusion process.
