Process flow of precision casting

Pressing wax (wax injection moulding) --- repair wax - wax inspection - group tree (wax module tree) --- shell making (first dip, sand, then paste, and then mold Shell air-drying) --- dewaxing (steam dewaxing) --- mould shell roasting - chemical analysis - pouring (pouring molten steel in the mould shell) --- vibration shelling ---Cutting and separation of castings and pouring rods----Grinding gate---Initial inspection (burr inspection)---Shot blasting-----Machining-----Polishing---Product inspection--- Warehousing

The casting production process is roughly like this. Generally speaking, it can be divided into pressing wax, shell making, pouring, post-processing, and inspection.

Pressing wax includes (pressing wax, repairing wax, group tree)

Pressing wax---Using a wax press to make wax molds

repair wax---correct wax mold

group tree --- group Lamo into tree

Shell making includes (hanging sand, hanging slurry, air drying)

Pouring includes (baking, chemical analysis also called spectroscopy, pouring, shock shell, cutting gate, grinding gate)

post-processing includes (sand blasting, shot blasting, correction, pickling)

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