1,Cast Iron Manhole Cover Description : A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material. Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them. A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques. 2,Main Features of the Ductile Iron Manhole Cover: ·High endurance ·High Strength ·Pressure Resistence ·Anti-corrosion ·Anti-theft ·Good visual effect Product information: Manhole Covers are manufactured for construction and public use. Manhole Covers shall be smooth and free from sand holes, blow holes, distortion or any other defects Designs .EN124 A15, B125, C250, D400, E600 and F900 A60005 for casting design 4,Manhole Cover Specifications: 1. material:ductile iron 4. D400, C250, B125 5. According to EN124 5，FAQ: We have organized several common questions for our clients，may help you sincerely： Q. Can I fit a square manhole cover into a round chamber? A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers. Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why? A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this. Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything? A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require. Q. Odours are coming through where I have installed my manhole cover, why? A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable. Q. I need access through my manhole cover on a regular basis, is this possible? A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.

- Q: Why does the precision casting factory not usually make iron castings?
- Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting
- 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. At least spend money on research and development, then the quality should be all right.
- Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- As a pig iron smelting, iron smelting belongs to physical, two belongs to the chemical refining, smelting, smelting generally not as a product after use, the product can be used as a chemical composition and casting the two refining, in general is to scrap as additional material after melting making products; engine castings have professional manufacturers making castings. You can own professional production of engine castings.
- 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: The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
- Q: What is the difference between casting and stamping parts?
- Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
- 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?
- There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
- 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!!
- Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
- Q: Shandong foundry, casting small pieces of precision casting
- Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
- Q: The difference between sheet metal and casting parts
- Commonly used in machine tools casting material is gray cast iron, casting bearing alloys can also be.
