v Lightweight allows more loading per vehicle, more convenient transportation and economical saving.

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:Why does the surface of stainless steel casting mirror mirror ripple?
Those should be head prints. If required, it would be better to throw with a single grinding head.
Q:Stainless steel mirror polishing precision casting parts is very difficult, 20
Buffing should be better, to see how your embryo, but a bit difficult
Q:Domestic large steel castings factory which is better, recommend!
At least spend money on research and development, then the quality should be all right.
Q:How to distinguish the forging parts and casting parts accurately
Distinguishing between forging and casting can be done from the following points:From the principle of distinguishingForging processing of machining by hammer or press and other equipment for forging parts produced in hot state, casting processing of metals into liquid, pouring into the cavity with a specific shape, produced by machining parts after cooling solidification. Simply say that forging is the metal soft pinch molding, and casting the metal into thin cooling solidification.
Q:How to cast iron and wrought iron collocation
3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.
Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
The main content of red sand table (Institute of soil science, China) silica 79.4%. three 1.48%. three 10.55%. two aluminum oxide iron oxide, calcium oxide 0.85%. Magnesium Oxide 0.52%. 1440. refractory mud 3.06% LOI 1.98% red sand with high silicon content, permeability is strong, durable, high refractoriness, good angle, low moisture content, less mud the casting finish is high, the basic requirements of sand should meet the following requirements: Casting of high purity and cleanliness, with silica sand as an example, iron sand SiO2 content of more than 90%, the big steel casting requests the SiO2 content of more than 97%; the high refractoriness and thermal stability; the suitable particle the shape and particle composition; it is not easy to be wetted by the liquid metal; cheap. The particle shape and composition of casting sand particle shape and particle composition permeability properties such as mobility, sand compaction, permeability, strength and resistance to liquid metal effects, is an important indicator of the quality of casting sand.
Q:What is the difference between forging parts and casting parts?
The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.
Q:What is the difference between casting and stamping parts?
Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
Q:When there is no flaw detection for large casting parts, is there any crack inside?
According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
Q:Heat treatment process and purpose of casting parts
Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
