Disclosed are injection moldings, an injection-molding apparatus and a method thereof. The injection-molding apparatus comprises: a cavity mold having a cavity; a core mold having a core surface to form a molding space for injection moldings when being joined to the cavity mold; a heating unit for heating the cavity mold or the core mold; a cooling unit for cooling the cavity mold or the core mold; and a patterning stamp having a micrometer or nanometer sized pattern and provided on an inner surface of the molding space. According to the injection-molding apparatus, a micrometer or nanometer sized pattern is formed on a surface of injection moldings so as to have a super-hydrophobic characteristic and an optical characteristic, and a micrometer or nanometer sized pattern of a complex structure can be implemented.

Injection moldings, injection-molding apparatus and method thereof

The coating material includes: polysilicate having 27.6 parts by weight to 36.2 parts by weight; one of epoxy resin and vinyl resin having less than 10.6 parts by weight; colloidal silica having 21.2 parts by weight to 42.6 parts by weight; and an additive having less than 10.6 parts by weight and including at least one hydrophile material selected from the first group consisting of &#x2014;OH, &#x2014;NH, and &#x2014;COOH and at least one hydrophobic material selected from the second group consisting of &#x2014;CF2and &#x2014;SiR.

Anti-fingerprint coating material for stainless steel outer case of home appliance

The present invention discloses a ultra-hydrophilic and antibacterial thin film coated metal product, and its manufacturing method. In order to easily produce an air conditioning metal material having excellent hydrophilic performance, aging property, corrosion resistance and antibacterial property on an industrial production scale without a special preprocess or postprocess, an anticorrosive thin film is selectively formed on both surfaces of a metal substrate sheet, and an ultra-hydrophilic and antibacterial Ti&#x2014;(Ag, Cu and/or Co)&#x2014;O&#x2014;C group compound thin film is coated on both surfaces of the metal substrate sheet on which the anticorrosive thin film has been or not been formed. The metal substrate sheet is mechanically processed into a target shape.

Ultra-hydrophilic and antibacterial thin film coated metal product, and it's manufacturing method

A method for manufacturing an ultra-hydrophilic thin film coated metal product having excellent hydrophilic properties, aging properties and corrosion resistance in an industrial scale production wherein the thin film includes an HMDSO anticorrosive thin film selectively formed on both surfaces of a metal substrate sheet, and an ultra-hydrophilic Ti&#x2014;O&#x2014;(C)&#x2014;(H) group compound thin film is coated on the anticorrosive thin film. The metal substrate sheet is mechanically processed into a target shape.

Method for manufacturing ultra-hydrophilic thin film coated metal product, and ultra-hydrophilic thin film coated metal product

An ultra-hydrophilic Ti&#x2014;O&#x2014;C based nano-film of which deposition thickness was improved and deposition uniformity was excellent was fabricated by mixing a Ti precursor and a liquid having a low boiling point and a high volatility&#x2014;at a uniform ratio. The catalyst accelerates a vaporization of the Ti precursor and facilitates the Ti precursor to be injected into a reaction chamber, thereby improving plasma polymerization efficiency.

Ultra hydrophilic Ti-O-C based nano film and fabrication method thereof

Disclosed are a surface treatment system that includes a deposition chamber () for forming a deposition layer at a surface of an object of surface treatment (); a carrier () for carrying the object of surface treatment () by mounting thereon, and a power applying unit () for forming a deposition reaction by applying a power to the object in the deposition chamber (), wherein the power applying unit () includes a fixed power applying unit () installed in the deposition chamber () and connected to an external power source (); and a movable power applying unit () installed at the carrier () for being electrically connected to the fixed power applying unit () movably as the carrier on which the object of surface treatment () is mounted goes into the deposition chamber and thereby applying a power to the object of surface treatment mounted on the carrier by contacting thereto.

Surface treatment system and method thereof

A surface treatment system in which gas for a deposition reaction is injected into a deposition chamber and power is applied to form a deposition reaction to form a deposition layer at a surface of an object or surface treatment, wherein the deposition chamber has a plurality of deposition spaces disposed in parallel and a convey unit for conveying one or more objects of surface treatment to each deposition space or discharging the objects of surface treatment from each deposition space after a deposition reaction.
