Abstract
The invention discloses a hollowed-out craft door handle and a manufacturing method thereof. The hollowed-out craft door handle structurally comprises a door handle body; the door handle takes the shape of a hollow tube; and a hollowed-out decorative hole is formed on the surface of the door handle. The manufacturing method comprises the following steps of: firstly designing pattern-text flat surfaces of the door handle to be manufactured and a hollowed-out part, then carrying out mechanical engraving by using resins instead of woods, and engraving template samples; placing two layers of adhesive films between mould frames, and respectively arranging an upper cover and a lower cover above and under the mould frames; burying the manufactured templates in the middle of the mould cavities, subjecting the templates to vulcanization to form a mold and opening a casting runner; then placing the mould in a centrifugal casting machine, switching a power supply on, pouring molten zinc, throwing the molten zinc into mold cavities to encase a loose core, and after 30 seconds, taking out the mould and extracting out the loose core to form a hollowed-out product, wherein the hollowed-out product is a blank product; and finally burring, polishing and electroplating the hollowed-out product to form the hollowed-out craft door handle. According to the hollowed-out craft door handle and the manufacturing method thereof, materials are saved, and the strength of the hollowed-out craft door handle is not reduced on the basis that the hollowed-out craft door handle has the decorative effect; and the manufacturing method of the hollowed-out craft door handle is simple and convenient and is suitable for volume production, thereby reducing the production cost.
Description
Technical field
