Product Description:

Specification of Ductile Gully Grates B125:

Class B125: EN124

The access covers and grates of this class are capable of withstanding a 400KN(-40 tonnes) test load

Use:

carriage ways, hard shoulders and pedestrian areas where cars and lorries have access.

Features of Ductile Gully Grates B125:

1. High load rating and strength

v Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.

v Less noise and lower vibration transmissions.

2. Against theft and safety options

v Zero theft value, reducing potential accident and further maintenance cost caused by thieves.

v Surface anti-slip thread guarantees safe road condition even in extreme weather.

v Locks are available as an option molded into the cover to improve security rate.

v Non-electricity conduction and non-heat conduction.

3. Lightweight

v Compared with cast iron manhole covers, composited covers are 50% lighter.

v Lightweight allows more loading per vehicle, more convenient transportation and economical saving.

v Allows a safer working condition, which a SINGLE worker is enough when installation without risk of injury.

4. Durable service life.

v More than 30 years service life without crack and color fading, comparing to 5 years of cast iron.

v Anti corrosion,water, dust and pets tight, well sealed prevent poisonous gas leaking out.

v Without displacement, freely radio signal passing.

v Higher and lower temperature tolerance with the range -40°C-200°C.

v Wear indicators available when thread depth is in a danger value.

5. Free design

v Much more clear resolution ratio of surface design than cast iron or BMC.

6. Carbon footprint saving and environmental care.

v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.

Packaging:

Metal band, plastic, wooden pallet. As per customers' requirements

Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: German winter three step mirror polishing 2013 new processYou can free proofing!

Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.: I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .

Q: How to improve the surface roughness of casting parts?: One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.

Q: What should I pay attention to when designing a casting structure?: (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.

Q: What is the difference between casting and stamping parts?: The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning and rectification are several main stamping processes. The difference between stamping parts and castings: with thin, uniform, light, strong features, stamping can be produced by other methods difficult to make, with stiffeners, ribs, UPS or flanging of the workpiece, to improve its rigidity. Due to the use of precision molds, the workpiece accuracy up to microns, and repeated high precision, specifications consistent, you can punch out of the hole, lug and so on.

Q: Which surface is coarser for cast iron or cast steel castings? Why?: The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.

Q: When there is no flaw detection for large casting parts, is there any crack inside?: According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified

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: What do you mean by "proofing" in the casting? Do you charge for the proofing?: Die die must charge, wood cheap, expensive aluminum mold

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?: The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.
