Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?: Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.

Q: What are the casting parts used to test shrinkage holes?: 3 fluorescent magnetic powder, this method can also be found in part.

Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?: The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.

Q: Why do cheap cars like stamping parts instead of casting parts?: We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.

Q: Casting parts have poor surface finish. What sand is used to make them?: Now resin sand, coated sand and other processes are also very good surface.

Q: What's the density of the cast iron? The density is thin and the density is thin: Uneven casting density is caused by uneven shrinkage of the casting during solidification.

Q: How to cast iron and wrought iron collocation: 3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.

Q: Which surface is coarser for cast iron or cast steel castings? Why?: The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.

Q: What reason is the bronze statue choking fire?: The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
