A molded article has an exterior surface, a non-exterior surface, and a projecting or recessed portion provided on at least one of the exterior surface and the non-exterior surface. A repeated pattern of projections and/or recesses or a texture face, which serves to disturb the flow of resin, is provided on the non-exterior surface.

A method of manufacturing a molded resin component having a decorative pattern by filling a cavity with resin includes using a mold set in which a concave portion is formed along a boundary portion between the plurality of pieces, the concave portion being used to form one portion of the convex portion of the decorative pattern, or using a mold set including a step formed when a base material is cut, and when a cutting tool is replaced at a position where a concave portion is to be formed, the concave portion being used to form one portion of the convex portion of the decorative pattern.

In one embodiment, a system for conditioning a preform for molding includes a heating cavity for receiving the preform, a heater configured to heat a gas, and a blower configured to force the gas heated by the heater into the heating cavity. In another embodiment, a method of conditioning a preform for molding includes positioning the preform in a heating cavity and forcing a heated gas into the heating cavity onto an exterior surface of the preform.

Glass filler-reinforced solid resins and methods of making the same. The method includes contacting a flowable resin composition and a tool. The flowable resin composition includes a flowable resin and glass filler. The method includes molding or forming the flowable resin composition with the tool. The method includes curing the flowable resin composition, to form the glass filler-reinforced solid resin. Substantially all the surface of the tool that contacts the flowable resin composition during the curing thereof has a surface roughness R.sub.a of about 2 microns or less. A refractive index of the glass filler is within about 0.100 of a refractive index of a cured product of the flowable resin in the glass filler-reinforced solid resin.

Provided are a production method of a mold having a recessed pattern, and a manufacturing method of a pattern sheet having good accuracy and excellent productivity. The production method of a mold includes: a step of preparing an electroform having a protruding pattern and a mold having a first mold and a second mold forming a cavity; a step of fixing the electroform excluding an end portion of the electroform to the first mold; a clamping step of clamping the electroform excluding the end portion of the electroform and a region of the protruding pattern between the first mold and the second mold to form the cavity; and an injection step of filling the cavity with a resin.

The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.

Implementations of the invention comprise a molded part, especially a decorative part and/or paneling part for a vehicle interior fashioned as a molded part, comprising a backing, especially a plastic backing, and a decorative layer, especially a wood veneer, wherein the decorative layer has a rear side facing the backing and a front side designed as a visible side, wherein at least one light source, especially a laser or a LED designed as the light source, is provided on or in the molded part. Implementations of the present invention also comprise a method for producing a molded part according to the invention.

The present disclosure discloses an anti-fatigue mat and methods for making the same. The method for making an anti-fatigue mat includes providing a leather comprising a first surface and a second surface opposite to the first surface, forming a color layer on the first surface, cutting the leather, putting the cut leather into a mold, injecting an elastomeric material into the mold, curing the elastomeric material to form an elastic layer on the second surface and a plurality of concave structures corresponding to the plurality of protruding structures on the first surface, and polishing the first surface to remove the color layer without caving towards the second surface. The anti-fatigue mat can have anti-fatigue performance and vivid stereoscopic impression, where being simple to fabricate with low costs and can be industrialized.

A method of manufacturing a microfluidic device comprises molding a substrate using a master die having at least one outer stepped formation; and forming at least one microstructured formation having an outer rim, the depth of the outer rim being shallower than that of the microstructured formation.

A tool insert for the production of an object by an injection molding method, wherein the injection molding tool includes an insert frame and at least one lamination assembly having a plurality of individual laminations, wherein the at least one lamination assembly is inserted in the insert frame. In further aspects, the invention relates to a method and a system for producing an object having curved surfaces using the tool insert, and to an object which can be produced with the method. The system for producing an object comprises a tool insert and a sliding element. A basic idea of the invention is that curved surfaces can be introduced into the object in that the insert frame has curved surfaces and/or at least one distortion cushion is arranged between the insert frame and the at least one lamination assembly.
