FAQ
1.Q: Are you factory ?
YES! We are a professional ductile iron &gery iron casting Factory in China.
2.Q: How long can you make your quotation:
Within 3 workdays after received your detailed product information
3.Q: Do you provide OEM Service?
Yes, we provide OEM Service.
4.Q: What 's your quotation element?
Drawing, material, weight and quantity.
- Q:How to improve the surface roughness of casting parts?
- One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
- Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
- The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
- Q:My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?
- Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.
- 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！！！
- 1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
- Q:What is the difference between casting and stamping parts?
- Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.
- 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:How can the casting be quenched and tempered?
- Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
- Q:Why does the surface of stainless steel casting mirror mirror ripple?
- Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.
- 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.
- Q:What's the cause of the choking of the casting?,
- 2. when casting mold exhaust condition is not good, in the casting material use consider whether and hinder its gas permeability; in the process to consider to release more pores, multi venting; core exhaust is particularly important.
