Know-How to Transfer The Technology

The faucet's main production procedures include casting, mechanical processing, surface treatment,  assembly and testing etc. .

1. Casting process

a. Product design

b. Mold design and manufacturing

c. Mold's repair and maintenance

d. Sand mixing/mixer

e. Sand Core blower

f. Low-pressure die casting machine/heavy casting 

g. Sand cleaner 

h. Sawing machine
 

The most important production procedure is casting. The sand core's quality plays an important role in this production process, as it forms water channels in the faucet body during casting. A solid core is made from fine sand and a hardening agent by heating in a core box.

The core is made from fine sand and it forms the waterways for the faucet body during the casting

                   sand core's production

During casting, the shell mold is dipped into a water and graphite bath. The operator places the cores inside the mold and removes any loose sand from the shell mold using compressed air.

The cores are placed inside the mold.

The mold is sealed and placed in the blazing-hot casting chamber of the casting furnace. Three tons of molten brass flow from the casting furnace into shell molds. The core maintains waterways open inside the mold, to which technical components are installed and through which water flows through the faucet.

Molten brass flows into the shell molds.

After cooling down, the caster uses tongs to move the cast to cool down. Next, the core is removed from inside the faucet body by whirling it in a mill equipped with metal balls.

LPDC casting steps

Cooled faucet bodies delivered from the foundry are separated from each other by sawing, and any parts that were necessary during casting but not included in complete faucets are removed.

2. Machining

Get the brass casting after annealing, using a CNC numerically-controlled machine tool and another machine tool to process the brass casting,to make it dimensional, accurate, and position meet drawing requirements.

Proceed to polish, take outrags, rough surface, and potholes on the surface, and make the product surface have no obvious sand holes and hole defects after completion of machining. Grinding polishing processing, after polishing, use the high-speed rotating wheel to grind workpiece surfaces, make it smooth and bright, and increase the brightness of the product surface.

3. Surface treatment.

Matte and Bright Chrome electroplating line,   PVD (Physical Vapor Deposition) vacuum coating processes. 

4. Accessories process

The shaft, screw nut, screw, etc., which are used for faucets, need to forge and press from the copper bar into copper pieces, and then Processed thread according to the need by the machining technician, commonly known as tapping.

5. Assembly

After faucet castings pass the test after plating, then into the assembly process. Assembly is the processing that content faucet components according to certain order and technology, become a complete set of faucet products, and realize the function of the product design process reliably.

6. Testing
