1.Cast Iron Manhole Cover Description :

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.

5FAQ:

Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?

A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.

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: How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
Q: How to improve the surface roughness of casting parts?
First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
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: 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: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described
Q: What are the causes of pitting on the surface of a precision casting?
There is a bump on the mold. Or casting cooling fast.
Q: How to distinguish the forging parts and casting parts accurately
Distinguish from performance:The processing performance of forged parts is higher than that of the same material. The forging parts are compact and have good mechanical properties, but the casting parts may have sand holes, holes, shrinkage holes and other defects, and their mechanical properties are inferior to those of forgings. At the same time, forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with mechanical properties and long service life good.
Q: We are small castings, the need for surface treatment of shot blasting machine, about how much?
The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine,
Q: Why should pig iron be used in casting?
Popular name is called pig iron, in fact, is a kind of cast iron without treatment, after casting, in iron elements to add other elements to improve casting performanceIt mainly improves the fluidity, reduces the melting point and reduces the shrinkage.Usually pure iron and cast iron at the eutectic point (about 4.7% carbon content) can be used for castingThere are many kinds of cast iron, usually grey cast iron, ductile iron and vermicular graphite iron......
Q: Can the casting part be phosphating with the phosphating solution of the pickling board?
Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required
