FAQ

Why imported Composite Manhole cover/Grating from China?

1. Very competitive price, it will save you third or even half cost;

2.Good quality, don't worry much about the quality, actually, most of the building materials you buy from Miami, Dubai ,Italy, South Africa or your local market are imported from China. So why not buy direct from China. The key point is to find a reliable supplier who is honest and professional to take care of the quality and delivery time.

3. China has full range of Manhole covers which Follow En124  for your market, like A15,B125,C250,D400.

How do we start our cooperation?

If you are wholesaler, please send us the detailed information of the products you are doing, like Cover size, clear opening size, loading Grade, we will give you our best advices. We can start from sample order. 

 Sometimes if meet the size we don’t have, the new mould with your size and design can be considered from us. Let's talk more details about the New Mould and Charges. Then start our Cooperation.

Q: What's the effect of casting copper?
Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
Annealing is needed to eliminate stress and refine grain
Q: How do casting parts remove stress?
Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably 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: Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?
The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot
Q: What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q: What should I pay attention to when designing a casting structure?
The basic structure of unit 3 in the design of metal casting casting and its parameters are selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting casting casting; (2) the inner wall of the internal ribs and the thickness of a should be connected the outer wall thickness of 0.6 to 0.7, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage; (3) to prevent generating white grey cast iron, in addition to taking measures in the process, must make the wall thickness is not too thin (some information that cast fillet at the corner of the wall thickness of 15mm or more, with metal casting casting must be in the corner, for Aluminum Alloy, metal casting magnesium alloy castings shall not be less than 3 ~ 4m; (4) because of the metal type and the core that, for To facilitate the extraction of castings and casting out type, slope casting should be suitably large than sand casting metal casting, the general should be 30% ~ 50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction of the metal type the surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal casting type should be given greater inclination.
Q: Why should pig iron be used in casting?
Not necessarily is iron, steel, stainless steel, aluminum, copper can be cast iron, is cheaper, and better properties of cast out, for example, is not easy to rust, high strength, easy processing and so on, and is the only iron iron cast out, it is not necessarily the raw pig iron, plus some other material
