FAQ

1.Q: Are you factory ?
      YES!  We are a professional ductile iron & grey iron casting  Factory inChina.
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 much is the amount of electrophoretic paint per square meter used in the casting?
It was a very simple question, and it was complicated by what you said.In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.
Q:What are the casting parts processing engineering?
According to the classification of process methods, sand casting and special casting.
Q:How to get rid of casting sand inside casting parts?
Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
Q:How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
Q:Why does the surface of stainless steel casting mirror mirror ripple?
The surface can be improved by a little more than Xiasha
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: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!
Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust
Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.
