The production processing of the Brass Faucets

The production process of the faucet:

Product structure design-mold fixture design and production (casting workshop-die casting workshop-forging workshop-injection workshop)-machining workshop-polishing workshop-electroplating workshop-parts storehouse-assembly workshop-finished product warehouse.

At present, the most commonly used in sanitary ware factories is gravity casting: under the action of the earth's gravity, molten metal is poured into a metal cavity to obtain a casting. Then the basic raw materials used are: copper alloy, zinc alloy, and aluminum alloy. Working temperature: 990℃-1010℃. Castings can be used as semifinished for the following parts of the faucet: body (main body), water outlet, decorative cup, gland, handle, copper sleeve, copper core (spool seat), base, etc.; faucet casting process: core-casting-drain Sand-sand washing-saw runner-finishing.

3. The definition of die-casting: it is a method of using high pressure to press molten metal into a metal mold with a complex shape. Dissolution temperature: 400C°-450C° Die casting can be used to make the following parts in the faucet: decorative cups, glands, handles, copper sleeves, bases, panels and other non-waterproof parts. The surface of the zinc alloy die casting is a dense layer with a thickness of about 0.1mm and a porous structure inside. When designing the mold and adopting the die-casting process, try to make the surface of the workpiece as smooth as possible to reduce casting defects such as cracks, pores, cold cracks, flash and burrs.

4. The definition of injection molding: a method of mixing completely melted plastic materials at a certain temperature with a screw, injecting them into the mold cavity with high pressure, and then cooling and solidifying to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. Molding temperature: 200C°-240C° The injection workshop can produce the following parts in the faucet: decorative cups, panels, fixing rings, O-rings, showers and other parts. Raw materials: ABS, PP, PVC, PC. PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), PF (phenolic plastic) and amino plastic.

5. The definition of machining: refers to the process of changing the shape, size or performance of a workpiece through a kind of mechanical equipment. According to the different processing methods, it can be divided into cutting processing and pressure processing. The machinery required for processing includes CNC lathes, electrical discharge machines, universal grinders, machining centers, laser welding, wire cutting, general and cylindrical grinders, internal grinders, etc. Precision lathes can be used for turning, milling, planing, and grinding of precision parts, and can process various special-shaped parts. Process the following faucet parts: body (main body), water outlet (elbow), copper core, copper sleeve, joint, gland, decorative cup, handle, panel, valve core, water separator and other parts.

6. Polishing workshop Polishing definition: refers to the high-speed rotation of various abrasive belts, grinding heads or linen (cloth) wheels of polishing machinery to process the surface of the faucet. Polishing can produce faucet parts: body (main body), water outlet (elbow), copper sleeve, decorative cup, handle, panel, diverter and Others parts. Basic polishing process: 60#-90#-180#-320#-400#-600#-800#-hemp wheel-cloth wheel.

7. The basic definition of electroplating: the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.), and enhance beauty. So how are plastic non-metallic products plated with metal materials? This requires sensitization and activation of non-metallic products to achieve the desired surface.
