Wax Injection

Mix liquid wax slurry and solid wax together, inject wax into metal mould, fetch it out after cooling.

Wax Mold Assembly

Heat the stainless steel welding knife, weld the wax molds together on the gate stick according to technically designed. 

Dipping

The wax molds are dipped into waterglass solution, with surface coated by the solution.

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.

  

Wax Removal

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

Sand Shell Preheat

Heat the sand shell in order to strengthen the shell.

  

Casting pouring

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. 

   

Sand Shell Removal

Make the casting free from sand by shaking.

  

Cutting

Oxyacetylene cut off the castings from gate stick. 

  

Grinding

Grind the ingate and defected surface with grinding wheel.  

  

Heat treatment

Heat treat the casting by nomalizing, annealing, quench+tempering, induction quenching, case hardening and Nitriding per material spec

  

  

Machining

Machine the castings by CNC according to drawing spec.

  

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.

  

Pack & Transport

After rust prevention, pack the parts into plywood or iron case for transportation.
