Casting Process
Process Features:
● Use a fusible easy-to-use mold and a primary core; use an
integral wax mold and an integral cavity without opening the mold;
● Fluid shell: The coating is bonded to the sand to form a shell,
and the coating has good copyability to the wax pattern;
● Hot shell casting: pouring under the hot shell, the metal liquid
filling is good.
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.
