the processing of our precision casting 

1.       Process Design:Design the tooling according to customs' drawing or sample, set up the pouring

           system with CAE casting simulation software

2.       Mould Fabrication:Transfer the drawing or sample into 3D drawing which is applied to aluminum or

           steel mould fabrication

3.       Wax Injection:Mix liquid wax slurry and solid wax together, inject wax into metal mould, fetch it out

           after cooling

4.       Wax Mold Assembly:Heat the stainless steel welding knife, weld the wax molds together on the gate

           stick according to technically designed
5.       Dipping:The wax molds are dipped into waterglass solution, with surface coated by the solution

6.       Stuccoing:Stucco the dipped wax molds with quartz sand, then dip into induration solution

           containing ammonium chloride & magnesium chloride and hang to dry. The whole process repeats 6 times

7.       Wax Removal:Put the thick coated wax molds into wax removal gutter, keep heating. After lost all the wax only sand shell was left

8.       Sand Shell Preheat:Heat the sand shell in order to strengthen the shell

9.       Casting:Put the raw material into the induction furnace and melt, add with chemical composition per

material spec. After the temperature of molten steel rises to about 1600 degrees, take a pre-pouring

chemical analysis, if approved then pour liquid steel into the sand shell by ladle, make sure the shell is

filled with liquid steel and then cool off, meanwhile take the testing bar for after-pouring analysis

10.   Sand Shell Removal:Make the casting free from sand by shaking

11.   Cutting:Oxyacetylene cut off the castings from gate stick

12.   Grinding:Grind the ingate and defected surface with grinding wheel

13.   Heat treatment:Heat treat the casting by nomalizing, annealing, quench+tempering, induction

quenching, case hardening and Nitriding per material spec

14.   Machining:Machine the castings by CNC according to drawing spec

15.   Final inspection:Test the parts' mechanical properties by tension tester, impact tester, hardness

tester, take NDT with X-ray, UT and M.P.T, final dimension inspection are down by CMM, Measures &

Gauges, etc

16.   Pack & Transport:After rust prevention, pack the parts into plywood or iron case for transportation.
