A soil-resistant transfer sheet which includes, in the following order, a substrate sheet (a), a soil-resistant layer (b), a coating layer (c), and optionally an adhesive layer (d), wherein a surface of the soil-resistant layer, which reveals after the substrate sheet (a) is removed, has a contact angle with water of 100° or larger and a contact angle with hexadecane of 40° or larger; a process for producing a molded resin by in-mold labeling using the transfer sheet. The soil-resistant layer (b) is a layer obtained from a soil-resistant composition, and the coating layer (c) is a layer obtained from a polymerizable coating composition. The soil-resistant composition especially preferably is a perfluoropolyether urethane acrylate composition. Also disclosed is a process for producing the soil-resistant transfer sheet.

To provide an injection mold capable of filling a necessary resin material for obtaining a desired molded article in a cavity space of a fine mesh structure, there is provided an injection mold according to an embodiment of the present invention composed of a core mold and a cavity mold, in which a cavity space is formed when the core and cavity molds are in a contact with each other, the cavity space surrounding a plurality of contact areas between the core and cavity molds. In the injection mold according to an embodiment of the present invention, at least one of the core and cavity molds has a through-hole which has an opening in a parting plane of the core and cavity molds and extends from the opening to an outside of the injection mold, the parting plane corresponding to the contact areas between the core and cavity molds.

A cup-type container obtained by compression-forming a thermoplastic resin and including at least a flange portion, a body portion and a bottom portion, wherein a ratio (L/D) of the height of the container to the diameter of the opening is not less than 1.0, and if the direction of height of a test piece cut out from the body portion of the container is denoted by x and the circumferential direction thereof by y, a half-value width P at a half peak of a Miller index at a diffraction angle 2θ=14.5° that represents the diffraction by the crystal plane (110), is in a range of 1.25 to 1.5 over the whole body portion in a peak intensity profile in the direction of height (x-direction) of a Debye's ring obtained by measuring the diffraction intensities by causing the X-rays to be incident on an x-y plane of the test piece at right angles thereto. The cup-type container is evenly oriented in the direction of height of the container and in the circumferential direction thereof, has an even strength in all directions and has excellent heat resistance. The invention, further, provides a method of forming the cup-type container.

A composition of matter includes a particle, a resin bonding functionality bonded to a first portion of the particle, and a lubricating functionality bonded to a second portion of the particle.

An injection mold assembly for injection molding an object includes a first mold tool having a first tool surface and a second mold tool having a second tool surface. The first and the second tool surfaces are cooperatively configured to define a mold cavity between the tool surfaces for an injection molding of an object. The first mold tool has a tool element with a first side that has the first tool surface, and with a second side opposite the first side. Multiple fins extend from the second side of the tool element. A base supports the fins. The tool element, the fins and the base define a coolant flow cavity at the second side of the tool element. A method of designing the mold assembly is also disclosed.

A method of manufacturing a damping device, notably for a steering tie rod, the said device comprising a rod which extends along a main axis and which is intended to be connected to a first mechanical component, a securing portion which surrounds the said rod and which is intended to be connected to a second mechanical component, and a sleeve made of elastomeric material which is arranged between the rod and the fixing bushing so as, through elastic deformation thereof, to allow at least axial movement of the fixing bushing with respect to the rod, in which method the fixing bushing is offset axially with respect to the rod to force the elastic deformation of the sleeve and the introduction of a corresponding preload, then the sleeve is locked so as to keep it, when the device is at rest, in a state of permanent axial elastic deformation and preload.

A part formed by additive manufacturing includes a plurality of layers including a first layer and a second layer, the first layer and the second layer being stacked along a stacking direction, and a work surface formed on an upper surface of the first layer and an upper surface of the second layer. The part also includes a first through-hole formed in the first layer, a second through-hole formed in the second layer, the second through-hole being at least partially aligned with the first through-hole, and a wall extending from the first through-hole to the work surface.

Methods for manufacturing cushioning elements for sports apparel are described. A method is provided for manufacturing a cushioning element for sports apparel from randomly arranged particles of an expanded material. The method includes positioning a functional element within a mold and loading the mold with the particles of the expanded material, wherein the loading occurs through at least two openings within the mold and/or wherein the loading occurs between different movable parts of the mold.

A hot stamping apparatus and a hot stamping method are for collectively decorating a plurality of decoration objects using a decorative sheet. In a hot stamping apparatus, an upper chamber and a lower chamber are partitioned by a partition sheet and pressing bodies, so that decorative sheet pieces can be used instead of a decorative sheet having a large area. Then, by using the decorative sheet pieces, local thermal deformation can be prevented. A usage amount of the decorative sheet can be reduced, and three-dimensional decoration can be implemented as needed on a portion requiring decoration.
