Specific requirements for casting defect inspection

This specification clarifies the specific requirements for casting defect inspection and is applicable to the inspection of castings of this company and outsourced companies.
1. The casting surface must be clear and correct, and there must be no wrong characters, missing characters, or unclear characters.
2. There must be no single sand holes or pores on the casting surface that exceed 1MM, and shallow but piece-by-piece casting defects. Sand holes and pores on the casting surface that are less than 2MM can be repaired and smoothed with putty if they are not on the sealing surface and do not affect the wall thickness.
3. The flash, burrs, and box seams on the casting surface must be polished and smooth.
4. The casting must not have obvious defects such as deformation, shrinkage, lack of meat, box expansion, and box misalignment. For the gate frame, its thickness dimension must be inspected with the corresponding inspection fixture; for the large cover of the check valve, the plane with the O-ring groove must be inspected with a flatness inspection fixture.
5. The asymmetry between the inner cavity and the outer shape of the casting shall not exceed 1.5MM (including the center and flange).
6. The inner cavity of the casting shall not have defects such as bulging, lack of meat, excess meat, burrs, etc., and its shape and size shall be inspected with the corresponding gate.
The gate used (DN40-200) shall be replaced every six months, and DN250-600 shall be replaced once a year.
7. The surface roughness of the casting shall refer to the roughness sample: ≤N11~12, see Appendix 1.
8. The surface cleanliness shall be visually evaluated according to ISO8501-Sa2.5, see Appendix 2.
9. Each casting that passes the inspection shall be marked with its own inspection mark.
10. The castings inspected every day shall fill in the "Casting Inspection Record" truthfully.
11. Each furnace of the outsourced casting shall be accompanied by a test block, which shall be brought with the goods. If there is no test block, the goods shall not be accepted.
12. This specification is applicable to both our factory and outsourced manufacturers.
All casting outsourcing manufacturers are required to conduct 100% self-inspection according to the above inspection items, and then the factory inspection personnel will randomly inspect 20% of the castings sent in. If unqualified items are found, the specification will be fully inspected or rejected, and the relevant manufacturer will re-inspect and sort out the project, and after completion, it will be submitted to the inspection personnel for re-inspection.
