Describe the process flow of precision casting in detail?
Wax pressing (die casting moulding) — wax repair – wax inspection – group tree (wax module tree) — shell making (first dipping, sanding, then dipping, and finally mold
Shell air-drying) — dewaxing (steam dewaxing) — mould shell roasting – chemical analysis – pouring (pouring molten steel in the mould shell) — vibration dewaxing —
Cutting and separation of castings and pouring rods—-Grinding gate—Initial inspection (burr inspection)—Shot blasting—Machining—Polishing—Inspection of finished products— 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)
Wax pressing — Use wax pressing machine to make wax molds
Repair wax—correct the wax mold
Group tree — Group wax mold 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)
