Q:The cause of fracture and why there is no toughness: This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.

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:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you: Service performance: heat conductivity, friction reduction, shock absorption, heat resistance and corrosion resistanceTo compare these properties, it depends on the specific material, structure, and use of the parts. Otherwise, there is no comparisonS

Q:Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?: Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.

Q:What are the factors affecting the machining process of the casting material and structure?: The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.

Q:our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!: The pre treatment temperature and the quality of plastic powder are likely to be problems

Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?: Tangshan Yongding automobile spare parts factory also give a lot of supply, casting factory of Tangshan n to the car enterprises casting wheel gearbox etc.The team of casting experts welcome you to ask questions and accept questions!

Q:The difference between sheet metal and casting parts: Commonly used in machine tools casting material is gray cast iron, casting bearing alloys can also be.

Q:Where is the precision casting factory?: Everywhere is. Look what you want to do

Q:Why should pig iron be used in casting?: 1, in the absence of special requirements, the most important thing is that the price is cheap.2, pig iron castings quenching process requirements are not high. You can do it by hand.3, pig iron casting hardness is very large, can meet many requirements.4, pig iron castings, high temperature resistance is relatively strong. Like stoves are pig iron castings.5, pig iron casting plasticity is very bad, but in some experiments, but use this weakness to improve the sensitivity of the experiment.Wait
