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: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:Why does the precision casting factory not usually make iron castings?
Because it is too cheap, the design of materials is cast iron, generally do not have very high requirements.
Q:Why do cheap cars like stamping parts instead of casting 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. The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and straightening are the main types of stamping machines.
Q:Is the cast steel a casting part?
Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts
Q:What is the ejection angle of the die casting (Tan Gang)?
Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:What is the casting material?
Kdl1588n said in detail, casting a lot of material, steel, iron, aluminum, copper, zinc, etc. can be, valuable, as well as gold and silver, the most common on cast steel and cast iron, cast aluminum and so on.
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
Q:What's the effect of casting copper?
Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.
Q:What are the general technical requirements for casting parts?
Satisfy appearance quality (appearance defect, quality change, size deviation)Intrinsic quality (composition, properties, internal organization)Service performance (abrasion resistance, corrosion resistance, heat resistance, pressure resistance)
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
