Wax pressing (wax model made by shooting wax) — wax repairing-wax inspection-group tree (wax module tree) — making shells (dip the slurry first, drench the sand, then dip the slurry, and finally mold

Shell air-drying) — Dewaxing (steam dewaxing) ——- Mold shell roasting-Chemical analysis-Pouring (Pouring molten steel in the mold shell)-Vibration shell removal —

Cutting and separation of castings and pouring rods-grinding gate-initial inspection (blank inspection)-shot blast cleaning-machining-polishing-finished product inspection Warehousing

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

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

Wax pressing — wax wax machine for making wax mold

Wax repair — modify wax mold

Group tree — group the wax model

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

Pouring includes (roasting, chemical analysis also called spectroscopy, pouring, shock shell, cut gate, grinding gate)

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

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