A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion, which has a first surface having a smooth surface portion, and a second surface having plural sections, wherein each of the plural sections has a width and includes one or more convex portions which have one or more ridge lines extending in a ridge line direction. The ridge line direction of the one or more convex portions of at least one of the plural sections is different from the ridge line direction of the one or more convex portions of one or more of others of the plural sections. When the first surface of the resin molding is observed from outside, the resin molding has metallic appearance.

The present invention relates to a polyvinyl acetal resin film, comprising a polyvinyl acetal resin material, wherein at least one surface has a relative diffuse reflectance of 3% or higher at a wavelength of 550 nm, an absolute difference between the relative diffuse reflectance of one surface at a wavelength of 550 nm and that of the other surface at a wavelength of 550 nm is 0.5% or larger, and the amount of a plasticizer in the polyvinyl acetal resin film is 0 to 20% by mass based on a total mass of the polyvinyl acetal resin film.

The present invention provides a composite optical reflective film for a backlight source system and a preparation method therefor. The composite optical reflective film comprises a transparent diaphragm and a reflective diaphragm, wherein the reflective diaphragm is spliced to the transparent diaphragm through an adhesive, and the other face of the reflective diaphragm is coated with a reflective coating. The composite optical reflective film has good dimension stability, is not easy to warp and deform, has a higher reflectivity, has a simple preparation process and is easy to operate.

The invention relates to pelletizing thermoplastic road marking substance containing light-reflective agents, such as glass beads. A dry formulation of the ingredients is transported to a heating station, where the dry mix is heated to a molten state. The melted mix is extruded into form pockets of a moving conveyor. As the conveyor moves through a cooling station, the molten substance in the form pockets solidifies forming individual pellets. The pellets are then removed from the form pockets, packaged and shipped to customers.

A manufacturing device for an optical sheet according to the present invention includes a first belt 34 extending on a first heating roll 31 and a first chill roll 32 and a second belt 44 extending on a second heating roll 41 and a second chill roll 42. The first heating roll 31 presses, from the surface of the second belt 44, a second belt non-contact portion PT2 of the second belt 44 facing the first belt 34 where the second heating roll 41 is not in contact with the second chill roll 42. The second chill roll 42 presses, from the surface of the first belt, a first belt non-contact portion PT1 of the first belt 34 facing the second belt 44 where the first heating roll 31 is not in contact with the first chill roll 32.

A shaping apparatus, a shaping method, and a shaping program with which a shaped object can be formed to have the interior with excellent color expression are provided. A 3D printer forms a three-dimensional shaped object having an interior colored, with layer bodies of a light reflective material and a coloring material ejected from an ejection head based on color image data layered. The 3D printer determines arrangement positions of a light reflective material and a coloring material so that the light reflective material is arranged at a predetermined position in each unit volume in a region to be colored inside a shaped object and the coloring material is arranged around the light reflective material based on the color image data. A set position of the unit volume is set to make one surface of one unit volume come into contact with a plurality of other unit volumes.

A weatherable, low heat build-up capstock system comprising an acrylic cap, a pigment system that is IR transparent to a greater degree than existing pigment systems, an IR reflective substrate, and an extrusion system for same.

The present invention relates to a biaxially oriented polyester reflective film capable of retaining excellent reflection characteristics even after vacuum compression molding and hot press molding by suppressing deformation of an internal porous layer of the reflective film during molding, and a process of producing the same.

A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

A wire grid structure and a manufacturing method therefor, and a projection screen are provided. The manufacturing method includes: extruding a molten mixed material body in a melt extruder to a casting roll to form a casting piece; patterning the casting piece by means of an impression roll to form a precursor having a preset wire grid structure pattern, where the precursor is wound on the impression roll and has a first dimension in a height direction; stretching the precursor by a first group of stretching rolls and a second group of stretching rolls in two opposite directions along a direction perpendicular to the height direction to form the wire grid structure, a preset distance being configured between the first group of stretching rolls and the second group of stretching rolls. The wire grid structure has a second dimension in the height direction that is greater than the second dimension.
