Product Description

Faucet Production Process By Low Pressure Die Casting Machine 0

Faucet production process consists of four parts,casting,mechanical processing,surface treatment,and assembly.

  1. Casting process
  1. Product design
  2. Mould design and manufacturing
  3. Mould tidy up
  4. Mix sand
  5. Sand core shooter
  6. Low pressure die casting machine
  7. Short blasting cleaning out the sand core
  8. Sawing cutting

get the brass casting after annealing, using CNC numerically-controlled machine tool and other machine tool to process the brass casting,to make it’s dimensional,accuracy,and position meet drawing requirements.


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


3.Surface treatment.

Surface treatment technology mainly include PVD (Physical Vapor Deposition), ORB (Oil Rubber Bronze),electroplating plating etc., most widely used is electrochromism.Electroplate can enhance corrosion resistance of faucet, increasing hardness, prevent abrasion, surface beauty. Most common is hexavalent chromium electroplating,now green trivalent chromium plating is rising. Electroplating can be divided into three layers,first layer acid copper plating,second nickel plating and three chrome plated. International standard of faucet electroplating thickness is 8 microns, the best can reach 12 micron.


Plating surface treatment can be used 24 hours acetic acid salt spray test to judge quality, and can use layer thickness meter to authenticate each metal coating thickness.Usually if coating thickness can reach standard,salt spray test can pass. Electroplating is big pollution and big energy consumption,general faucet factory have to send faucets to professional electroplating factory to plating, thereby increasing production time and difficulty of control.


For direct drinking water faucet, need lead washing treatment after plating processing,get rid of the lead on faucet surface. After secondary water washing,chemical degreasing, de-lead by alkaline and acid, make our products conform to the American NSF61,lead content under 8 ‰, make product more conducive to human health. (2015 AB1953 regulation is more strict).
