There are several casting processes for stainless steel precision castings?
Stainless steel precision casting is a kind of object made of metal casting, which can be manufactured into various shapes and has a wide range of applications, such as the blank of machinery and equipment parts, valve body blank, etc. So there are several kinds of casting process of stainless steel precision castings?
There are many casting processes for stainless steel precision castings, such as metal mold casting, dewaxing casting, sand casting, investment casting, etc., among which sand casting and investment casting are more commonly used.
The casting process selection of stainless steel precision castings is mainly determined by the structural characteristics of the castings, such as wall thickness, shape and weight volume, etc. The suitable casting technology should be selected according to the structural characteristics of different castings.
The following are the characteristics of the two casting processes commonly used in stainless steel precision castings:
1. sand casting
1. Because of the advantages of selecting internal sand core, live block appearance, gasification mold and other special construction methods, castings with complex appearance can be produced and processed;
The size and weight volume of the casting are almost not limited, and the weight volume of the casting is usually tens of grams to hundreds of kilograms;
Sand casting has certain limitations on the minimum wall thickness of castings.
2. investment casting
1, can cast a very complex form of castings, its complexity is any other casting methods are difficult to achieve. Rewriting the whole sentence Although the investment form that can be made by one press is relatively simple, multiple press forms can be used to make various parts of complicated parts respectively, and then welded together to form the investment form of complicated parts;
2, investment casting can cast a clear pattern pattern, text content;
3. The minimum diameter of the hole can be cast up to 0.5mm, and the minimum wall thickness of the casting is 0.3mm, but it is not suitable for casting castings with large wall thickness.
