Problems solved by technology

[0002] Gold is a very precious metal, and jewelry made of gold is even more precious. Traditional gold jewelry is not carefully crafted, the processing effect is not ideal, and it is relatively rough. The surface gloss of the processed jewelry is relatively poor.
Moreover, most of the traditional jewelry processing technologies are the same, which cannot meet the needs of customers.

Embodiment

[0041] A kind of high-quality goods gold bar ornament point sand process is:

[0042] Wax injection: ① Select the rubber mold according to the variety required by the order.

[0043] ②Inject the melted wax into the rubber mold under pressure.

[0044] ③Take out the wax board after the wax has cooled down.

[0045] ④Remove the burrs on the wax board.

[0046] ⑤Weld the required wax plate to the water inlet (wax tree).

[0047] ⑥ The wax melting temperature is 70-90°C, and the maintenance temperature is 30-50°C, depending on the temperature

[0048] There are slight differences depending on the type of wax, and the pressure of the wax chamber is 0.3-0.5Mpa

[0049] Pumping powder: ① After the welding powder is connected, the wax tree at the water inlet is put on the casting cylinder.

[0050] ② Stir the gypsum according to (38-40) water: 100 gypsum and remove the air.

[0051] ③ Pour the gypsum slurry into the casting cylinder and pump out the air to reduce the air bubbles...

Abstract

The invention discloses a pointing sand process of bullion jewelry, comprising pouring wax-drawing powder-roasting mold-reversing mold-holding mold-grinding-blowing sand-pointing sand-milling-shaping. The process combines with two technique of engraving and nailing sand. The product is subjected to nailing sand (pointing sand) using the surface density (fineness) of the diamond needle, therefore the contrast effect of the product is enhanced with more nicety and higher efficiency and the surface gloss of the product is very light and beautiful.

Description

technical field [0001] The invention relates to the field of jewelry processing, in particular to a sand spotting process for high-quality jewelry. Background technique [0002] Gold is a very precious metal, and jewelry made of gold is even more precious. Traditional gold jewelry is not carefully crafted, the processing effect is not ideal, and it is relatively rough. The surface gloss of the processed jewelry is relatively poor. Moreover, most of the traditional jewelry processing technologies are the same, which cannot meet the needs of customers. Contents of the invention [0003] The purpose of the present invention is to provide a kind of high-quality goods gold bar ornament pointing sand technology, and this technology is to combine these two kinds of technologies of car embossing and nailing sand and develop, utilize the surface density (smoothness) of diamond needle to carry out beading (sand pointing) to product ) treatment can enhance the contrast effect of the...
