Method for manufacturing stainless steel water tap

Abstract

The present invention provides a fabrication method of a stainless steel water faucet, which belongs to the technical field of items in daily use. The present invention resolves the problems of the prior water faucets, such as high cost, low rate of finished products, complex technique, etc. The fabrication method of the stainless steel water faucet includes five steps: (A) the fabrication of a shell mold: the melted wax is infused into a mould, and after the wax is coagulated, the mould is opened in order to obtain a wax model matching the valve body of the water faucet; the outer surface of the wax model is evenly coated with adhesive slurry, which then evenly adhibits sand grains on the outer surface of the wax model, the shell mold is produced after steam is applied to thoroughly take off the wax in the shell mold, and the shell mold is then baked; (B) the fabrication of the valve body; (C) the fabrication of a cover plate and welding; (D) the polishing of the valve body; (E) assembly: a valve core, a valve rod and a handle are produced. The fabrication method of the stainless steel water faucet has the advantages of simple technique, easy embodiment, saving of materials and low cost, and moreover, because the water faucet is made of stainless steel material, the water faucet is not faded and rusted, so the appearance is good.

Description

technical field [0001] The invention relates to a faucet, in particular to a manufacturing method of a stainless steel faucet. Background technique [0002] Water taps are widely used in daily life, and existing water taps are usually made of copper material. Such material makes the heat conduction of the faucet fast, that is to say, the temperature of the faucet will rise in a short time after hot water passes through the faucet, and people are easy to be scalded when operating the faucet. Therefore, the existing faucets are less safe to use. [0003] Simultaneously, in order to reduce cost, lead is added in copper material, because lead has influence on human health, therefore, drinking the drinking water discharged by above-mentioned faucet for a long time is harmful to human health. [0004] In addition, the above-mentioned copper material will be oxidized and faded, which will affect its appearance, so it needs to be electroplated on the outside. Moreover, if the fauc...

Problems solved by technology

Such materials make the faucet conduct heat quickly, that is to say, the temperature of the faucet will rise in a short time after hot water passes through the faucet, and people are easily burned when operating the faucet. Therefore, the existing faucets are less safe to use

[0003] Simultaneously, in order to reduce cost, lead is added in the copper material, because lead has influence on human health, therefore, drinking the drinking water discharged by above-mentioned tap for a long time is harmful to human health

[0004] In addition, the above-mentioned copper material will be oxidized and faded, which will affect its appearance, so it needs to be electroplated on the outside

Moreover, if the faucet is not used for a long time, there will be patina inside the faucet.

[0005] In order to solve the above problems, people have designed a stainless steel faucet, but the valve body of the faucet is directly made by casting through a mold, so the material consumption is more, and its cost is correspondingly higher.
