Q:What are the causes of pitting on the surface of a precision casting?
There is a bump on the mold. Or casting cooling fast.
Q:What are the requirements for casting steel castings?
1, high quality requirements of the surface or the main processing surface should be placed below.
Q:What are the casting parts processing engineering?
At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.
Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
According to the grade of the parts, according to the relevant standards, the regular drawings will be noted in the technical requirements of the parts.
Q:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described

Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
Q:Is the cast steel a casting part?
Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast
