精密铸造这一铸造方式，其是相对于什么而言的？其的主要优势，是什么？
Compared to what is the casting method of precision casting? What are its main advantages?
在铸造方式中，精密铸造是其定州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院中之一，而且，从专业角度来讲的话，其是相对于传统铸造工艺而言的一种铸造方式。其的主要优势，是为，可以获得较为准确的形状，以及在铸造性能上，也是非常好的。所以，可以很好利用这两点，来进行合理利用，获得质量好的铸件。
Precision
casting is one of the casting methods, and from a professional
perspective, it is a casting method compared to traditional casting
processes. Its main advantages are that it can obtain a relatively
accurate shape, and its casting performance is also very good.
Therefore, these two points can be well utilized for reasonable
utilization to obtain high-quality castings.
2.精密铸造中的硅溶胶精密铸造，其主要是用在哪儿的？
Where is the main use of silica sol in precision casting?
精密铸造，其是有很多种类的，而其中的硅溶胶精密铸造这一种，其在具体应用上，主要是在一些精密零件上，以及，一些结构较为复杂、外观光洁度高且形位公差要求高的铸件上。而且，在机械制造中，是零件的成型方法之一，在某些领域中，是有广泛应用的。
There
are many types of precision casting, among which the silica sol
precision casting is mainly used in specific applications on some
precision parts, as well as on castings with relatively complex
structures, high appearance finish, and high geometric tolerance
requirements. Moreover, in mechanical manufacturing, it is one of the
forming methods of parts, which is widely used in some fields.
