Precision casting process

Wax pressing (injection molding) ---- wax repairing ---- wax inspection -- group tree (wax module tree) ---- -- shell making (first dip pulp, pour sand, then dip pulp, and finally mold

Shell dry) - dewaxing (steam dewaxing) -- -- -- -- -- - mold shell roasting, elasticity analysis, casting (within the shell mould casting molten steel) - vibration - to moult his shell

Separation, castings and casting rod cutting grinding gate - test (MAO embryo screening) -- -- -- -- -- -- -- -- the shotblast cleaning machine -- -- -- -- -- -- -- -- polish finished product - into the Treasury

Casting production process is generally like this in general can be divided into wax, shell, pouring, post-treatment, inspection

Wax pressing includes (wax pressing, wax trimming, tree setting)

Wax press -- use wax press to make wax models

Wax -- correct the wax mold

Group tree -- group tree with wax model

Shell making including (hanging sand, hanging pulp, air drying)

Pouring includes (roasting, chemical analysis also known as playing spectrum, pouring, shaking shell, cutting gate, grinding gate)

Post-treatment includes (sand blasting, shot blasting, correction, pickling)

Inspection includes (wax inspection, initial inspection, intermediate inspection and finished product inspection)
