Provided is a molding hook and loop fastener, in which a barrier erected near left and right side edges of a substrate includes at least two rows of vertical wall arrays, and the vertical wall array positioned on the outermost side includes a plurality of gaps provided at a predetermined pitch in a length direction. At least two of the gaps are provided on the vertical wall array positioned on the outermost side with respect to a region between the engaging elements adjacent in the length direction of the substrate. Due to this, in the molding hook and loop fastener, an outer side and an inner side of the barrier can be divided by the vertical wall array, and flexibility of the molding hook and loop fastener can be improved.

Method and apparatus are disclosed for a wire harness routing aid. An example wire harness routing aid for a vehicle includes an extruded core made of a thermosetting polymer. The example wire harness routing aid also includes a plurality of wires positioned around an exterior of the extruded core. Additionally, the wire harness routing aid includes a fastening layer to affix the plurality of wires to the extruded core.

The disclosure provides a runner protection tube for steel casting and a manufacturing method thereof. The runner protection tube for steel casting is made of a slurry composition for forming the runner protection tube for steel casting, the slurry composition includes organic fibers, inorganic fibers, thermosetting resins, thermoplastic resins, inorganic particles, inorganic binders, water, a lubricating oil and a hydrating agent.

A high strength multilayer film includes a film-web having an odd number of layers, the film-web includes a bonding layer located between two core-strength layers, wherein the film-web is formed from a concentric-multilayer polymer structure in which an inner layer of the concentric-multilayer polymer structure includes a bonding material. For the bonding layer of thickness 2*Z and the two strength layers of thickness Y each, the film-web has a tensile strength at yield that is greater than of a film-web that (i) lacks the bonding layer and (ii) includes a single core-strength layer of thickness 2*(Y+Z).

A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 ?m and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.

Provided are films such as high-stalk films made from polyethylene polymers, and methods for making these films. Such films preferably have at least one of the following properties: (a) MD 1% Secant Modulus of less than 400 MPa, (b) Elmendorf Tear MD of at least 100 g/mil, (c) Dart drop of at least 200 g/mil, (d) puncture resistance break energy of at least 120 mJ/m, (e) TD shrink at 150 C. of at least 40% or at least 30% at 120 C.; and (f) haze value of less than 40%.

An assembly for reshaping an elongated plasticized article includes a heated fixture upon which the elongated article is supported in adhering fashion to a contoured upper surface. Following heating, the article is transferred to a cooling fixture exhibiting a further contoured upper surface and, upon subsequent cooling, the article exhibits a final multi-dimensional extending profile matching the contoured upper surface of the cooling fixture. A further variation of the assembly includes an elongated and bowed track supporting a fixed jig at an end thereof. A slidable jig is traversable along the track and actuated by a ram in directions towards and away from the first jig. Upon a first length extending portion of the article being pre-secured to the slidable jig, a first forward feed direction of the article results in an end extending portion communicating within a multi-dimensional cavity establishing a contoured surface withing the fixed jig, subsequent rearward displacement of the slidable jig causes forcible reshaping of the elongated article as it is stretched and drawn against the contoured surface of the fixed jig.

The inner cannula (3) of a tracheostomy tube includes a shaft (30) extruded of an ePTFE material. The axial strength of the shaft is increased by heating elongate portions (34 and 35) along the shaft such as by contact with a heated roller (205). The heating is sufficient to alter the structure of the material and make the heated portions (34 and 35) more rigid than the remainder of the shaft.

A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

The present invention provides an agricultural film formulation, which comprises about 40 wt % to about 70 wt % inorganic mineral powder, about 15 wt % to about 30 wt % high-density polyethylene, about 8 wt % to about 20 wt % low-density polyethylene, about 5 wt % to about 10 wt % biodegradable plastic, and an optional auxiliary agent, based on total weight of the formulation. The present invention also provides an agricultural mulch film made from the agricultural film formulation and a preparation method thereof.
