Disclosed herein is a molded laminated structure having negative draft angles and methods of manufacturing a molded laminated structure having negative draft angles. A preliminary structure having a first outer layer and a second outer layer is molded with a bend that divides the preliminary structure into two sections with an angle between the two sections of less than 180-degrees. Portions that extends from the sections are at positive draft angles. A groove is formed in the preliminary structure at the bend but not formed in a constant cross-section of the second outer layer. The preliminary structure is folding along the bend to at least partially close the groove and form a molded laminated structure with portions that extend at a negative draft configuration while retaining the second outer layer continuous throughout the molded laminated structure.

The present disclosure provides a display motherboard and a method for manufacturing the same, a display substrate and a method for manufacturing the same, and a display device, and belongs to the field of display technology. In the method for manufacturing the display motherboard of the present disclosure, the display motherboard includes a plurality of display substrate areas each including a sub display area and a sub bending area; and the method for manufacturing the display motherboard includes: forming an adhesive force variable back film material having a first adhesive force on a flexible underlying substrate; removing the back film material in positions above the sub bending areas; and treating the remaining back film material to form a back film having a second adhesive force, wherein the second adhesive force is greater than the first adhesive force.

A structure including: a straight pipe made of a polyolefin-based material; a pair of ridges made of a polyolefin-based material, extending in a circumferential direction along an outer surface of the straight pipe, and spaced apart from each other in an axial direction of the straight pipe; a piping material including a plurality of metal-made separate cases, which are separated from each other in the circumferential direction of the straight pipe and enclose a portion of the straight pipe; and a pair of engagement portions formed on at least one of the separate cases and engaging respectively with the pair of ridges.

The present invention discloses a method and process to laminate packaging substrates using an adhesive tape. The tape has a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature and both of which are alternatively coated on at least one surface of the tape. The method consists of laminating this aforementioned tape to a packaging substrate by following the process of: placing this tape in or on a laminating machine over the packaging substrate, heating the tape at least to the second temperature while making contact with the packaging substrate, cooling the packaging laminate until the second heat activated adhesive is set and cutting a predetermined portion of the packaging laminate before a second adhesive occurs between the tape and the packaging laminate.

The present invention provides a multi-cup arrangement comprising a polypropylene sheet, wherein the polypropylene sheet comprises at least two cavities, the cavities each protruding from the sheet from a bottom surface of the sheet, wherein the cavities are separated from each other via one or more spacer area(s) on the sheet, wherein the spacer area(s) each comprise one or more groove(s) on the bottom surface of the sheet that are positioned to allow the sheet to be broken along the groove by bending the sheet towards the top surface, wherein the grooves are positioned to divide the sheet into multiple segments, each segment comprising one or more cavities, wherein each of the groove(s) has a maximum depth of ≥25% and ≤80% with regard to the thickness of the polypropylene sheet. Such multi-cup arrangement may be separated into individual cup segments by moderate manual force, whilst the arrangement does not undesirably bend nor snap under the action of its own weight.

An anti-graffiti window film covering system that includes multiple polymeric film layers. Each layer includes a unique visual indicia to identify the number of sheets remaining in the system.

A method for manufacturing an element for a bodywork component is provided. The method, characterized in that a rough form made of plastic and comprising at least one housing on a first face is manufactured, a connection member comprising a first end accessible from the side of the first face of the rough form and a second end accessible from the side of a second face of the rough form is pre-positioned with respect to the rough form, a heating track is positioned on the first face of the rough form, a connection part of the track is affixed to the first end of the connection member, the first end of the connection member and the connection part of the track are squeezed together and welded by the input of electrical energy, the first end of the connection member is positioned in the housing, and an additional layer of plastic is over molded.

A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (12, 2), capturing a portion of the parison (12, 2) within a mold (15), and inflating the captured portion of the parison (12, 2) against the mold (15). The captured portion of the parison (12, 2) is inflated against the mold (15) by introducing the liquid product into an interior of the captured portion of the parison (12, 2), wherein the liquid product forms an end product to be sealed within the resultant container.
