A component of a mold for molding preforms made of thermoplastic material, comprising

at least a first part (10) and at least a second part (20) adapted to mold part of the outer surface of a preform,

wherein, when the first part (10) and the second part (20) are assembled to each other, at least a first surface (11) of the first part (10) and at least a second surface (21) of the second part (20) face each other and are spaced apart from each other, thus delimiting a passageway for gases or vapors to leave the mold;

and wherein at least one of said first surface (11) and said second surface (21) comprises laser-induced periodic surface structures (LIPSSs).

A self-tapping screw made of synthetic material has a threaded shank defining a screw center line. The screw has proximal and distal insertion ends, the shank including first and second portions, the second proximal to the first. The pitch is the same in the first and second portions, and has a complete thread cross-section in the second portion. In the first portion, in the direction of the thread, the thread is divided into segments having an incomplete thread cross-section, the thread segments having leading end and trailing ends. The leading end of one thread segment extends further radially than the leading end of the thread segment preceding it and forms a cutting edge. In most of the thread segments the thread top in question, for substantially its full length, starting with the leading end, considered in thread direction, is situated at a constant radial distance from the center line.

An inline mixer device includes a flexible tube and a mixer portion. The mixer portion is internal to and integral with the tube. The mixer portion and tube may be comprised of the same flexible material. Methods of forming the inline mixer device are provided. Methods of mixing fluid with the inline mixer device are provided.

An inner mould tool forming part of a mould to be used during injection moulding of plastic articles, such as plastic tops for liquid food packages, is provided. The inner mould tool comprises an outer surface defining the interior surface of the plastic article to be produced, wherein the longitudinal end of the inner mould tool is provided with a bushing having a planar surface defining the longitudinal end of the inner mould tool and being configured to be in contact with mating outer mould tools during injection moulding. The bushing is provided with side walls extending from the planar surface, said side walls forming part of the outer surface of the inner mould tool.

An apparatus for molding a rotating member includes a main mold including a column part space configured to mold a column part therein, a plurality of blade spaces configured to mold a plurality of blades therein, and a plurality of split bodies disposed along a circumferential direction of the column part and configured to move along a radial direction of the column part. Each of the plurality of split bodies comprises a column part molding surface defining the column part space, and a plurality of blade molding surfaces defining the blade space. Column part molding surfaces of the plurality of the split bodies define the column part space together, and a first blade molding surface provided at one of the plurality of split bodies defines, together with a second blade molding surface provided at another one of the plurality of split bodies, one of the plurality of blade spaces.

A screw cap (14, 502) configured to be removably attachable to a bottle (12) includes a base (40) and an annular skirt (42, 508) extending downwardly therefrom. One or more threads (32) extend radially inwardly from an interior surface of the skirt (42, 508). A retention feature (509) extends radially inwardly from the interior surface of the skirt (42, 508). The retention feature (509) is configured to produce at least one of an audible response or a tactile response when the cap (14, 502) is rotated with respect to a bottle (12).

A pipe end protector for protecting pipe threads provided on a pipe end of a pipe component for exploration and production of a hydrocarbon well, said pipe end protector comprising a main body and an annular flexible lip seal, wherein the main body is made from a first polymeric material having a first elastic modulus, and the lip seal is made from a second polymeric material having a second elastic modulus which is lower than the first elastic modulus.

Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.

A method of manufacturing a monolithic fiber-reinforced polymer composite component is provided. The method comprises providing a mould comprising a main cavity and at least one additional cavity that extends from the main cavity; introducing a polymer matrix material containing chopped fiber reinforcement into the mould to fill the main cavity and the at least one additional cavity to form a monolithic fiber-reinforced polymer composite component with a main portion formed in the main cavity and at least one raised feature formed in the additional cavity and extending from a surface plane of said main portion. The at least one raised feature is arranged to incur visually perceptible damage when the component is subject to an impact with an energy above a predetermined impact energy threshold and to resist an impact with an energy below the predetermined impact energy threshold.

An adjustment element with which a component is fastenable and positionable in the space and including a sleeve-like hollow screw with a first and a second axial end and an outer thread to which a component can be retained and can be positioned in axial direction of the hollow screw, adjacent to the first axial end, the hollow screw has a fastening collar which is configured integrally and projects radially to the inside and which encompasses a tubular fastening opening of the hollow screw, and an axial support sleeve arranged within the tubular fastening opening so that the hollow screw is rotatably fastenable with a fastening means to a component in a rotatable manner, which passes through the axial support sleeve.
