The present disclosure relates to a decoration member comprising a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer comprises a molybdenum-titanium oxide (Mo.sub.aTi.sub.bO.sub.x).

A laser welding system is directed to simultaneously joining respective layers of a first bag and a second bag. The system includes a first film layer adjacent to a second film layer for forming the first bag, and a third film layer adjacent to a fourth film layer for forming the second bag, each layer of the plurality of film layers being made of a thermoplastic material that absorbs laser radiation having a wavelength of about 2 microns. A non-absorbing carrier film layer is positioned between the second film layer and the third film layer, the non-absorbing carrier film layer being made of a material that transmits substantially all energy of the laser radiation. A laser source applies the laser radiation toward portions of the plurality of film layers to be joined, forming the first bag generally simultaneously with the second bag.

One embodiment is an apparatus including a mold configured to manufacture a composite structure at a heated temperature. The mold includes a first mold tool configured to mold a first portion of the composite structure, wherein the first mold tool comprises a plurality of strands of a fiber-reinforced thermoplastic material, wherein the fiber-reinforced thermoplastic material comprises a thermoplastic embedded with a plurality of reinforcement fibers, wherein the plurality of reinforcement fibers is aligned within each strand of the plurality of strands; and an anisotropic thermal expansion property, wherein the anisotropic thermal expansion property is based on an orientation of the plurality of reinforcement fibers within the first mold tool; and a second mold tool configured to mold a second portion of the composite structure.

The present disclosure relates to a tensioning system for use in a stereolithography manufacturing application. The system may have a build plate for supporting a three dimensional part being formed using a photo responsive resin, a base plate and a release element extending over the base plate. The release element is configured to receive a quantity of photo responsive resin for forming a new material layer of the three dimensional part. A pair of tensioning components are secured to opposite ends of the release element, and apply a controlled tension force to the release element during peeling of the release element to reduce a separation force required to separate the release element from the new material layer after the new material layer is cured.

The present invention relates to a freeze-drying mold and a method for manufacturing water-soluble polymer balls using the same, more specifically to a freeze-drying mold that is provided with a first mold having a plurality of first accommodation grooves formed on underside thereof and a plurality of discharge portions formed on top thereof to communicate with the plurality of first accommodation grooves and a second mold having a plurality of second accommodation grooves formed on top thereof to be facingly coupled to the plurality of first accommodation grooves of the first mold to thus provide a plurality of accommodation portions, and a method for manufacturing water-soluble polymer balls using the same.

According to the present invention, the freeze-drying mold is capable of controlling the shrinkage rate of a solution in a freeze-drying process to make freeze-dried spherical materials, easily separating the made freeze-dried materials therefrom, and optimizing a drying efficiency thereof, and the method for manufacturing water-soluble polymer balls using the same is carried out so that the water-soluble polymer balls are constant in pore sizes and distributions, have high strength, and do not have any films on the surfaces thereof.

The present disclosure provides a mold for molding a polyurethane condom, and methods for manufacturing and using the mold. The mold (200) has a surface roughness of 0.2 or less, is formed from a thermoplastic polymer having a surface tension of 10-35 mN/m. The mold (200) for molding a polyurethane condom is prepared by injection molding the thermoplastic polymer. When the mold (200) is used, the mold (200) is hung vertically and dipped in an emulsion containing a polyurethane resin to obtain a dipped mold (200), then the dipped mold (200) is removed and dried to form a polyurethane film on its surface, and then demolded to obtain a polyurethane condom (100). The condom formed by the mold (200) is thin and has excellent flexibility and strength, satisfying the market demand for the product.

A macromolecule forming mold, which is integrally formed by a polymer body. Multiple communicated runners are formed inside the polymer body; a material injection port is penetrated in the surface of the polymer body, and the material injection port is communicated with the runners, so that a thermosetting castable fills the runners by means of the material injection port and is cured and molded, and the polymer body is damaged to take out a thermosetting elastomer. A thermosetting elastomer and a manufacturing method therefor. The thermosetting elastomer has the characteristics such as excellent physical properties and lightweight properties.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.
