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 reinforcing component for a refrigerator, which is formed by mixing a base material as a synthetic resin material and a supplement component formed by arranging reinforcing fibers according to a pultrusion method, and combined with one or more portions of on one portion of an inner side of an outer case of the refrigerator to contact with foam, a corner of the bottom of the refrigerator or in a mechanic chamber of the refrigerator, an outer plate or an inner plate of a door of the refrigerator, and the interior of a side wall forming an inner space of the refrigerator can reduce the weight of the refrigerator while maintaining the strength.

Reinforcing component for refrigerator

Disclosed are a fixing structure of insulation panels and a prefabricated refrigerator with the same. The fixing structure of insulation panels includes a recess recessed on one surface of a first insulation panel having an insulation portion inside a casing, and a protrusion formed to be inserted into the recess, on one surface of a second insulation panel having an insulation portion inside a casing, wherein the insulation portions of nonmetal material are exposed to a bottom of the recess and a front end of the protrusion so as to shield a transmission path of heat flowed along a casing contact surface of the insulation panels, thereby improving insulation efficiency.

Fixing structure of insulation panel of prefabricated refrigerator and prefabricated refrigerator having the same

A vacuum insulation panel and an insulation structure of a refrigerator applying the same are disclosed. The vacuum insulation panel comprises: a sealing cover () having an outermost layer exposed to the outside, a gas shielding layer stacked on the bottom surface of the outermost layer and formed of a thin metal sheet and a metal deposition film, and a heating-fusion bonding layer stacked on the bottom surface of the gas shielding layer and formed of an octane-base material; a core material () sealed by the sealing cover () in contact with the heating-fusion bonding layer, and provided with an extended insulation portion () some parts of which are extended between the bonding portions formed at the sealing cover (); and a gas permeation preventing layer () formed on the sealing cover (), so that can prevent an external air or moisture from penetrating into a vacuum insulation panel.

Vacuum insulation panel and insulation structure of refrigerator applying the same

Disclosed are a vacuum insulation panel and an insulation structure of a refrigerator using the same. The vacuum insulation panel comprises a core material formed by gather glass fiber, a getter having a container to receive an absorbent having quicklime of 90 wt % or greater as a main component, and a sealing cover formed to surround the core material and the getter. The core material can be formed at low cost in such a manner that glass fiber is tangled and gathered by penetrating glass wool having glass fiber using a needle. Since the getter is made of quicklime that can first remove water corresponding to a main component of the absorbent, the getter can be manufactured at low cost and has improved insulation efficiency.
