​What is the difference between ordinary casting and precision casting?

1. What are the differences in casting types between precision casting and general casting?

Precision casting, from a professional perspective, is a unique casting method compared to traditional casting processes. Therefore, there are many casting types, but most of them are dominated by sodium silicate casting. In ordinary casting, there is sand casting, but in precision casting, there is generally no sand casting, so this is the difference between them.

2. In terms of precision casting, what should lost foam casting manufacturers pay attention to when choosing specific methods? And, is it available for casting and precision casting of ferrous metals?

In precision casting, when choosing a specific method, what should be considered is the adaptability of the method, and whether the efficiency can be improved by using molding or core-making technology through facilities, etc. But for the casting of ferrous metals, precision casting can be used. Moreover, according to the characteristics of this casting, it can be used to produce some thick-walled lost foam casting parts.

3. What do you call precision lost foam casting? And, do parts obtained through precision casting need to be machined?

Precision lost foam casting, for this kind of mold, we call it precision lost foam casting, and it is an exclusive mold for precision casting. And the parts obtained through precision casting do not need to be machined. Because precision casting is a special casting, its casting specifications are very accurate and can meet relatively standardized requirements.
