Q:My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?: The common material that can be anodized is aluminum alloy. It is recommended to use casting aluminum alloys, such as ZL102 and ZL105, which are commonly used as cast aluminium alloys. The processing of aluminum casting is easy. After processing, the surface of the whole part can be anodized. The color can be chosen.

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:It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！: As a pig iron smelting, iron smelting belongs to physical, two belongs to the chemical refining, smelting, smelting generally not as a product after use, the product can be used as a chemical composition and casting the two refining, in general is to scrap as additional material after melting making products; engine castings have professional manufacturers making castings. You can own professional production of engine castings.

Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?: 4, the performance requirements of the steel: whether castings or welding parts, there may be quality defects, but the casting will generally be worse than the weldment.You should be able to make a choice in the end.

Q:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you: The performance is too extensive, I think the following several people all fall into the erroneous zone directly, the performance includes a series of aspects:Mechanical properties: tensile strength, yield strength, elongation and contraction ratio of section and impact toughness after etc.

Q:Cause of choking of casting parts: Is it boiling from the picture? Does it sound like a fire? If not, it's not choking. I feel like choking. The gas doesn't drain out

Q:Why do casting parts have air holes?: First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.

Q:The casting sand is going on: Dispersed sand inclusion is common on the surface and subcutaneous of steel castings, often concentrated on the outer surface of the upper box and the inner surface of the lower case, and a few of them are inside the cast steel parts.

Q:Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: It has something to do with the size of your work, and it has a lot to do with the blade you're using right now.

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.
