Q:In theory, which is more expensive, forging parts or casting parts?: The structure of the casting is relatively flexible in design, and the modeling is easy to realize.

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:How can the casting be free of trachoma?: Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;

Q:There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: Buffing should be better, to see how your embryo, but a bit difficult

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:Can the casting part be phosphating with the phosphating solution of the pickling board?: Phosphating. But it's not necessary. Because casting parts have strong corrosion resistance.

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?: The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.

Q:What is the difference between forging parts and casting parts?: No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions

Q:What is the ejection angle of the die casting (Tan Gang)?: Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle

Q:Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.
