InfluenceStainless steel precision castingThe purity and transparency of the oxide film are important factors. Its thickness, porosity, purity, and sealing quality all directly affect the mirror effect of the casting. For example, if the oxide film contains a lot of impurities, its purity will decrease, and the transparency of the cylinder will decrease.
Stainless steelInvestment CastingTo ensure stainless steelInvestment CastingTo achieve a mirror-like finish, the impurity content in the oxide film must be reduced. Therefore, the thickness, porosity, purity, and sealing quality of the film must be carefully controlled to minimize impact on processing. Impurities in the oxide film of stainless steel precision castings primarily originate from the casting itself, with some coming from the oxidation bath. Therefore, appropriately reducing the content of alloying elements in the casting can minimize impurity levels. Stainless steel precision casting is a minimal or no-cutting casting process, a superior technology in the casting industry with wide applications, suitable not only for casting various types and alloys.
The mirror finish process for stainless steel precision castings is also difficult to complete smoothly. To achieve good results, various influencing factors must be eliminated to ensure the process functions effectively, thereby improving the overall quality of the stainless steel precision castings.
To determine casting defects, one must consider their location, severity, and batch patterns simultaneously.
The same surface phenomenon may originate from the structural, mold, shell-making, melting, casting, or cleaning processes. The cause cannot be directly determined based solely on the defect name; analysis of the part and production records is necessary.
Confirm whether the defects are concentrated in thick areas, corners, hole edges, near gates, or in areas exposed after machining.
Distinguishing between sporadic, concentrated, recurring, or persistent problems helps narrow down the range of causes.
Simultaneously check wall thickness changes, fillet radius, feeding conditions, casting parameters, and post-processing.
Clearly define appearance, dimensions, non-destructive testing, or performance requirements before providing a quote to reduce delivery disputes.
