What is the technological process of stainless steel precision casting?

Wax pressing (wax injection to make wax mold) --- wax repair --- wax inspection --- group trees (wax module trees) --- shell making (first dipping, drenching, then dipping, Mold shell air drying) --- dewaxing (steam dewaxing) --- mold shell roasting --- chemical analysis --- pouring (pouring molten steel in the mold shell) --- vibrating shelling --- casting and rod cutting separation --- grinding gate --- initial inspection (rough embryo inspection) --- shot blasting cleaning --- machining --- polishing. --- finished product inspection --- Foundry production process is generally like this, generally speaking, it can be divided into wax pressing, Shell making, pouring, post-treatment and inspection of wax pressing include (wax pressing, wax trimming, tree grouping)

 

Wax pressing------using wax press to make wax mold.

Wax repair------modify the wax mold.

Group tree------the wax mold is grouped into a tree.

Shell making includes (hanging sand, hanging pulp, air drying).

Pouring includes (roasting, chemical analysis, also known as spectrum, pouring, shock shell, cut gate, grinding gate).

Post-treatment includes (sandblasting, shot blasting, correction, pickling).

Inspection includes (wax inspection, preliminary inspection, intermediate inspection, finished product inspection).

 

Cold iron, gating system and riser are often used together in stainless steel precision casting production to control the solidification process of castings and obtain qualified castings.
