v Allows a safer working condition, which a SINGLE worker is enough when installation without risk of injury.
4. Durable service life.
v More than 30 years service life without crack and color fading, comparing to 5 years of cast iron.
v Anti corrosion,water, dust and pets tight, well sealed prevent poisonous gas leaking out.
v Without displacement, freely radio signal passing.
v Higher and lower temperature tolerance with the range -40°C-200°C.
v Wear indicators available when thread depth is in a danger value.
5. Free design
v Much more clear resolution ratio of surface design than cast iron or BMC.
6. Carbon footprint saving and environmental care.
v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.

- 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.
- Q:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- uch as: automobile transmission shaft adopts mechanical rolling machine with good performance, gray cast iron can play seismic effect effectively, with good thermal conductivity of radiator graphite in gray cast iron, the aircraft engine turbine blade by casting directional solidification casting and Dan Jingzhu.Do everything we can to make the best use of it, the advantages and disadvantages of rolling and casting, and you'll find it yourself, Baidu, depending on how you use it
- Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- According to different casting process and parts materials, each has relevant standards, can be found online;
- 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: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:In theory, which is more expensive, forging parts or casting parts?
- It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
- 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!
- If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
- 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: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:When there is no flaw detection for large casting parts, is there any crack inside?
- Cracks are considered serious levels of defects and should be repaired
