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.


Q: Why does the surface of stainless steel casting mirror mirror ripple?
Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.
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!
The pre treatment temperature and the quality of plastic powder are likely to be problems
Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.
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 do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?
Casting parts do not need to provide drawings of casting blank, the casting factory according to your drawings in the required surface will be sufficient allowance, and the rest of the size according to the mechanical design manual and the casting manual can be found. The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q: What kind of flaw detector is better for casting parts?
If the casting is very small, can be used for fixed magnetic detection machines, of course with fixed magnetic powder the testing machine, the best first contact the manufacturers, because the fixed magnetic particle testing machine belongs to the non-standard equipment, according to the workpiece size, different shape, manufacturing daily inspection and measurement.
Q: Can the casting part be phosphating with the phosphating solution of the pickling board?
Phosphating. But it's not necessary. Because casting parts have strong corrosion resistance.
Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q: Shandong foundry, casting small pieces of precision casting
Dongying Huayang precision casting factory, the smallest to do 2G pieces.
