Precision casting refers to the general term for the process of obtaining precision-sized castings. Compared with the traditional sand casting process, the castings obtained by precision casting have more precise dimensions and better surface finish. It includes: investment casting, ceramic casting, metal casting, pressure casting, lost foam casting.
Precision casting is also called lost wax casting. Its products are precise, complex and close to the final shape of the parts. They can be used directly without machining or processing. It is an advanced process of near net formation.
Wax (wax waxing mold)---repair wax----wax inspection----group tree (wax module tree)---shell (first paste, sand, re-slurry, finally Mould air drying)---Dewaxing (steam dewaxing)-------Mould roasting--chemical analysis--casting (casting molten steel in the mold shell)----vibration shelling--- Cutting and pouring of casting and pouring rod----grinding gate---initial inspection (hairy inspection)---shot blasting-----machining-----polishing---finish inspection--- The warehousing and casting production process is generally such that it can be divided into waxing, shelling, pouring, post-treatment, and inspection of wax including (pressure wax, wax repair, group tree).
Wax---Use wax machine to make wax mold
Repair wax---correct the wax mold
Group tree---group the wax mold
The shell includes (hanging sand, hanging pulp, air drying)
Casting includes (baking, chemical analysis, also called spectroscopy, casting, shock shell, gate, gate)
Post-treatment includes (blasting, shot blasting, correction, pickling)
Inspection includes (wax inspection, initial inspection, intermediate inspection, finished product inspection)
