阿里巴巴不锈钢精密铸造又叫作熔模精密铸造。该工艺在铸造过程中尽量减少或者根本不进行切削，是一种少切削或无切削的铸造工艺，是铸造行业中一项优异的工艺技术。其应用范围非常广，不仅适用于各种类型、各种合金的铸造，
Stainless steel precision casting is also called investment casting.
This process minimizes or does not carry out cutting at all in the
casting process. It is a casting process with little or no cutting. It
is an excellent process technology in the casting industry. It has a
wide range of applications and is not only applicable to the casting of
various types and alloys,
而且生产出的铸件尺寸精度、表面质量比其他铸造方法要高。同时，耐高温、不易于加工的铸件，均可采用熔模精密铸造方式。这种铸造方式由于铸造过程中并不处于超高温状态，更适于铸造航空航天、国防等高精尖产业的元件。
Moreover, the dimensional accuracy and surface quality of the castings
produced are higher than those of other casting methods. At the same
time, investment casting can be used for castings that are resistant to
high temperature and not easy to process. This casting method is more
suitable for casting components in aerospace, national defense and other
high-precision industries because it is not in an ultra-high
temperature state in the casting process水玻璃型壳工艺发明时间很早，我国也在上世纪五六十年代从苏联引进了该技术。该技术成本低，操作相对简单，同时对原材料的要求也不高，
The sodium silicate shell technology was invented very early, and China
also introduced the technology from the Soviet Union in the 1950s and
1960s. The technology has low cost, relatively simple operation and low
requirements for raw materials,
在不锈钢精密铸造中使用较为广泛。不过，该技术相比于硅溶胶制壳工艺的最大问题是所得铸件的表面质量一般，尺寸精度较低。但因其成本具有优势，我国在部分民用或者低精度的内燃机上仍然沿用这一技术。该技术自引进以来，我国科研人员对其进行了比较大的改进，主要表现在改善型壳涂料、优化硬化剂、采用复合型壳等方面。
It is widely used in stainless steel precision casting. However,
compared with the silica sol shell making process, the biggest problem
of this technology is that the surface quality of the castings is
general and the dimensional accuracy is low. However, due to its cost
advantage, this technology is still used in some civil or low precision
internal combustion engines in China. Since the introduction of this
technology, Chinese researchers have made great improvements, mainly in
improving shell coating, optimizing hardener, using composite shell and
so on
