FAQ
Why imported Composite Manhole cover/Grating fromChina?
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: What are the casting parts used to test shrinkage holes?
- 1. anatomy. It is easy to slack off by sawing and machining.
- Q: Why does the surface of stainless steel casting mirror mirror ripple?
- The surface can be improved by a little more than Xiasha
- Q: Casting parts have poor surface finish. What sand is used to make them?
- Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- 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: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
- 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
- Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- There is YW1 best, if not using YG6X, YG8 is ok!The speed should not be high, the greater the diameter, the lower the speed! For example, a diameter of 100 mm, speed is not greater than 80 rpm, each point is good!The main tool is the front angle to be larger, more than 6 degrees, and the groove should be wider and larger to reduce the cutting resistance! When the rear angle is properly reduced and the strength is increased, it is recommended to take 3 degrees.The main components are: spindle box, exchange gear box, feed box, slide box, tool post, tail frame, light bar, lead screw, bed, foot and cooling device.Spindle box: also known as the headstock, it is the main task of the rotary motion of the main motor came through the transmission mechanism of a series of positive and negative spindle to be required two different steering speed, the spindle box gives impetus to the movement of the box. Medium spindle is the key part of lathe. The stability of the spindle on the bearing directly affects the quality of the workpiece. Once the rotation accuracy of the main shaft is reduced, the value of the machine tool will be lowered.
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
- Q: How can the casting be free of trachoma?
- Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;
