Q:Casting parts have poor surface finish. What sand is used to make them?
V casting, EPC, precision casting of the surface is good.
Q:How about casting parts for a year?
3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
Q:What is the casting material?
Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Valve sand core mold drying is not in place, excessive water content
Q:How to distinguish the forging parts and casting parts accurately
Distinguish from scopeShanghai Zhejiang forest auto parts experts pointed out that the forging process can eliminate cast loose, metal welding holes, so an important part of high load working conditions, severe machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging process. Because of its low cost and good economy, casting parts processing is widely applied and belongs to the basic process of modern machine building industry.
Q:What are the general technical requirements for casting parts?
What kind of casting do you want to know? Copper parts, iron pieces, aluminum pieces??? Their casting conditions are different.
Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
The types and uses of foundry sand according to the mineral composition of different silica sand and non siliceous sand is divided into two categories. The main mineral composition of silica SiO2.: natural silica sand used for non-ferrous metal casting, cast iron and steel castings in small sand and core sand. The selection of natural silica sand: used in organic matter as the binder of various sand and core sand. The artificial sand for sand and core sand castings. Non siliceous sand and non siliceous sand have many kinds and different uses. Limestone sand: crushed by limestone, the main mineral composition is CaCO3, used for casting sand and core sand. Zirconium sand: the main mineral composition is ZrO2 SiO2, used for large steel castings and alloy steel pieces of core sand or sand surface sand, or powder used as coating. Magnesia: the main mineral composition is MGO, used for high manganese steel casting surface sand, core sand, and its powder can be used as coating. Chromite ore: the main mineral composition is chromite FeO. Cr2O3, used for large or special casting steel surface sand, core sand, its powder can be used as coating.
Q:What's the density of casting?
Uneven casting density is caused by uneven shrinkage of the casting during solidification.
Q:What is the reason for 304 stainless steel precision casting parts to be changed?
Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.
Q:What is the difference between the casting drawing and the car work drawing?
Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems
