Quality Inspection:

The inspection of castings mainly includes dimensional inspection, visual inspection of appearance and surface, chemical composition analysis and mechanical property test. For castings that are more important or easy to cause problems in the casting process, non-destructive testing is required, which can be used for ductile iron castings. Non-destructive testing techniques for quality testing include liquid penetrant testing, magnetic particle testing, eddy current testing, radiation testing, ultrasonic testing, and vibration testing.

Manufacturing Process

Wax---Repair wax----Wax inspection----Group tree (wax module tree)---Shell (first paste, sand, re-slurry, finally mold drying)--- Dewaxing (steam dewaxing)-------Mould roasting--chemical analysis--casting (casting molten steel in the mold shell)----vibration shelling---separation of casting and pouring rods- ---Grinding gate---Initial inspection (hairy inspection)---Blasting shot-----Machining-----Polishing---Finishing inspection---Warehousing
The casting production process is generally such that it can be divided into wax, shell, casting, post-treatment, and inspection.
Pressure wax includes (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)
