Is it difficult to make a two-color K gold pendant?

Difficult. Two-color K gold needs to go through at least 14 processes. Process flow:

Beer wax mold → tree planting → powder filling and impression → baking powder → ingredients → inverted mold → roller polishing → mold holding → sanding → grinder polishing → carving → polishing → electroplating →QC (Testing)→Finished products are put into storage.

Introduction to the main process flow:

The beer wax mold is filled with the wax in the wax machine into the rubber mold (mold) according to the style and specifications specified by the customer, and the beer mold meets the requirements. wax model.

To plant a tree, weld the wax mold to the wax pole (commonly known as the tree pole).

Powder-filled impression: Place the welded wax mold tree into a steel cylinder, pour in gypsum powder (commonly known as injection powder), and use a vacuum machine to remove air bubbles in the powder to prevent casting. Trachoma (small holes) appears in K gold jewelry.

Baking Powder Place the powdered wax tree together with the steel cylinder into an electric furnace to heat and remove the wax (high temperature volatilization) until the powder temperature reaches the temperature of the K gold pouring mold (about 680°C). It takes time About 8 hours.

Ingredients for molten gold: Mix pure gold raw materials and patching (an alloy raw material used for K gold jewelry) in proportion to form K gold materials. If the K gold raw materials are imported, you can directly Smelted into processed jewelry suitable for single piece production.

Put the K gold material into the vacuum mold pouring machine or centrifugal mold pouring machine according to the required weight of each cup of workpiece. After being melted into liquid at 1100 degrees high temperature, put the powder cup (packed into The workpiece in the powdered cup is put into the pouring mold machine, and the molding machine is used to inject the K gold liquid into the workpiece in the powder cup, and the mold is molded into the required K gold tray.

Roller polishing: The molded gold support is polished by a roller machine to achieve a certain brightness on the surface.

Use the mold to take the barrel-polished empty gold holder, and perform the processes of filing, holding, hammering, and saving as required to trim the deformation and surface roughness of the empty gold holder to make it smooth and smooth. Trachoma (tiny holes).

Sand blasting uses a crane to smooth the surface of the product.

Grinding and polishing uses some chemical raw materials to remove contaminants on the surface of the empty gold support, and polishes it with a magnetic grinder.

Lathing uses a lathe machine equipped with a diamond lathe knife to carve patterns on the surface of the product.

For grinding, use soldering wax (polishing wax) or yellow or white cloth reels, large and small bristles, lint rods and other tools for thorough polishing with a flying saucer machine and a grinding machine.

Electroplating uses gold water or gold salts of various colors to electroplat the surface or part of the product to make the surface of the product brighter.
