A method of producing a brush for the cleaning of electronic components. In this method, a plastic core is prepared and submerged into a solvent to melt the outer surface of the core. While the outer surface of the plastic core is still partially melted, it is rolled through a trough of powdered polyvinyl alcohol (PVA) such that granules of PVA melt into and subsequently become embedded at the outer surface. As the solvent evaporates, the outer surface of the core re-hardens and the granules of PVA become firmly entrapped at the outer surface. The PVA covered shaft is placed in a mold, which is then filled with a PVA solution. As the solution cures, it forms a strong bond with the PVA granules that are embedded at the surface of the plastic core. Thereafter, the mold components are disassembled, leaving behind the finished cored brush.

Impellers made of composite materials with flow path cavities covered by an erosion resistant coating are manufactured by covering removable molds having shapes corresponding to a negative geometry of the flow path cavities, with the erosion resistant coating using plating or thermal spraying. After shaping and curing a composite material around the molds covered with the erosion resistant coating, the molds are removed, while the erosion resistant coating remains on the composite impeller.

A mold assembly for forming a film includes a transparent bottom mold, a top mold, a case, and a lighting member. The transparent bottom mold defines a cavity for receiving a workpiece and a plurality of liquid compositions. The top mold is matched with the bottom mold to accommodate the workpiece between the bottom mold and the top mold. The case receives the bottom mold and the top mold placed therein. Air in the case is exhausted from the case to coat the plurality of liquid composition on the workpiece. The lighting member emits light on the liquid compositions to solidify the liquid compositions to form a film on the workpiece.

Described herein is a process for producing molded non-crosslinked polymer materials including at least one at least partially coated surface, where a coating composition having release agent properties is used to coat the non-crosslinking polymer material. The coated materials show good optical properties as well as a good mechanical stability as well as a high flexibility. Further described herein are molded non-crosslinked polymer materials including at least one at least partially coated surface, which are produced by the process.

A mold assembly for forming a film includes a transparent bottom mold, a top mold, a case, and a lighting member. The transparent bottom mold defines a cavity for receiving a work piece and a plurality of liquid compositions. The top mold is matched with the bottom mold to accommodate the work piece between the bottom mold and the top mold. The case receives the bottom mold and the top mold placed therein. Air in the case is exhausted from the case to coat the plurality of liquid composition on the work piece. The lighting member emits light on the liquid compositions to solidify the liquid compositions to form a film on the work piece.

An injection molded part for a motor vehicle includes a film having a scratch-resistant layer, a plastic substrate molded to the film, wherein the plastic substrate is at least partially transparent or translucent, and a scratch-resistant coating molded to the plastic substrate on a side opposite the film.

A molding system and method, allowing for the repeated use of the same molding insert for purposes of elaborate objects molding is described. The proposed method allows for multiple moldings of intricate shapes and curvatures improving the mass production of the jewelry moldings. During the process, the raw molding material is squeezed through the narrow opening inside the mold form under pressure. As the molding material enters the mold form, it is coated with a coating fluid. After the curing, the molding material could be easily removed through a narrow cavity opening, promptly reassembling back to the shape of the insert for continuous use in the next steps of the molding procedure.

Implanted medical devices need a mechanism of immobilization to surrounding tissues, which minimizes tissue damage while providing reliable long-term anchoring. This disclosure relates to techniques for patterning arbitrarily shaped 3D objects and to patterned balloon devices having micro-or nano-patterning on an outer surface of an inflatable balloon. The external pattern can provide enhanced friction and anchoring in an aqueous environment. Examples of these types of patterns are hexagonal arrays inspired by tree frogs, corrugated patterns, and microneedle patterns. The patterned balloon devices can be disposed between an implant and surrounding tissues to facilitate anchoring of the implant.

Described herein is a composition which is suitable for coating components in an in-mold coating process, a process for coating components, and a method of using the composition for improving the flow behavior of compositions used for producing components. The composition includes at least one solvent L, at least one alkoxylated fatty acid and/or fatty alcohol, and at least one alkoxylated polysiloxane.

An object is to provide a manufacturing method of a fiber-reinforced resin that significantly reduces a resin filling defect on the surface and surface irregularity caused by a temperature difference between a molding temperature (curing temperature) and ordinary temperature in the course of molding the fiber-reinforced resin, and a product manufactured by the manufacturing method. There is accordingly provided a manufacturing method of a coated fiber-reinforced resin molded article and a product manufactured by the manufacturing method. The manufacturing method comprises a first molding process that cures a matrix resin which a reinforcing fiber is impregnated with at a temperature T1( C.) to obtain a fiber-reinforced resin molded article; and a second molding process that places the fiber-reinforced resin molded article in a cavity of a mold, sets the cavity to a temperature T2( C.) that is lower than the temperature T1( C.), injects a liquid coating layer-forming resin material into the cavity such as to coat at least part of a surface layer of the fiber-reinforced resin molded article, and cures the coating layer-forming resin material at the temperature T2( C.), so as to obtain the coated fiber-reinforced resin molded article, wherein the mold is comprised of at least two pieces and has the cavity in a shape that is approximately same as a shape of the fiber-reinforced resin molded article.
