摘要:
A multi-face part is provided on a half-finished product which eventually becomes a metal decorative button. The multi-face part includes a plurality of small sectional faces and ridges obtusely joining between two adjacent small sectional faces. An outside of the half-finished product including the multi-face part is plated. Then, the half-finished product is barrel-polished. Thereby, the plating on portions corresponding to the small sectional faces remains and the plating on portions corresponding to the ridges is removed, exposing the ground color of the half-finished product. Then, the multi-face part is partially compressed to form the metal decorative button having a compressed decorative surface. The compressed decorative surface is given a pattern composed of a plurality of small sectional parts corresponding to the small sectional faces with the plating left and boundaries corresponding to the ridges with the plating removed.

Methods of making tungsten carbide-based annular jewelry rings including sinterable metal and/or ceramic powder materials compressed into a predetermined configuration and then sintered to form an annular jewelry ring to which softer precious metals, stones, crystals or other materials suitable for use in jewelry may be affixed. Such items of jewelry may have multiple facets and can be fabricated using various disclosed techniques and various combinations of materials.

The present invention relates to a lightweight, anti-scratch and fracture resistant material for use in manufacture of jewelry prepared by sintering a powered mixture consisting essentially of 20% by weight of titanium carbide, 25% by weight of tungsten carbide, 35% by weight of titanium nitride, and balance being a binder consisting essentially of nickel, molybdenum and cobalt.
摘要:
There is provided a method for producing a multi-colored or multi-alloy extruded shape, such as metal tubing for use in forming rings. At least two contrastingly colored metal components or metal components made from different alloys are arranged in a container. The metal components in the container are compressed so as to form a billet of distorted multi-colored or multi-alloy metal. The billet is extruded thereby forming multi-colored or multi-alloy patterns in the extruded shape.

There is provided multicolored metal rings and multicolored metal tubing and a method for producing metal rings and metal tubing for use in forming multicolored rings. At least two contrastingly colored metal components are arranged in a container. The metal components in said container are compressed so as to form a billet of distorted multicolored metal. The billet is extruded thereby forming multicolored patterns in the tubing.
摘要:
A method and apparatus for reducing the amount of metal used in a chain as compared to a chain formed of a round wire, the method including the steps of forming a wire having a non-round shape, wrapping the wire around a mandrel to form a spiral of the wire, the mandrel formed such that it supports the non-round shape of the wire with a longer dimension of the wire extending radially from an axis of the mandrel, cutting the spiral of wire to form individual links of wire, and forming a chain from said links.

A woven, braided or knitted fabric structure includes wires of silver alloy, preferably a precipitation-hardened Ag Cu Ge alloy. The process for making a fabric structure may include providing silver wire having a temper of more than fully soft but less than half hardness, forming said wire into said structure and heating the structure to precipitation-harden the wire.

摘要:
A sizable ring and method of fabricating the same is disclosed. A first version comprises a first ring member, made of a hard metal (e.g., titanium), having a protrusion at each end thereof. The protrusions engage a second ring member made of a soft precious metal. The ring may then be sized in a conventional manner by cutting through the second ring member and adding or removing precious metal. In a second version, a link member includes pins at each end which engage openings or cavities in ends of one or more additional ring members. Other versions include rings with multiple link members. The methods disclosed herein are ideal for titanium rings.
