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 requirements for casting steel castings?
- 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
- Q:When there is no flaw detection for large casting parts, is there any crack inside?
- Cracks are considered serious levels of defects and should be repaired
- Q:What is the reason for 304 stainless steel precision casting parts to be changed?
- Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
- Q:Domestic large steel castings factory which is better, recommend!
- Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.
- Q:What method of casting does not rust? I think the sample is like oil
- Close to the solder, and slowly dissolve is hot melt double-sided adhesive, otherwise it is oily double-sided adhesive.
- Q:Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
- General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
- 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!
- You oily sludge!Is not the general market on the soil?If it isPlease use two groups of chemicals to reinforce the soilOr suggest your company?Do the putty or paint film after doingThat's better
- 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: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:Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- What kind of work, what kind of material, 204201304316, how big live ah? You ask?Can the 201 pieces of material and 304 of the pieces fit in a single car? Can I use the universal YG8 knife? Straight, knife, pipe thread?You should live to say, understand, say, do not understand, draw a simple drawing with Baidu doodle, marking the important size, this is good to answer ah!
