Features of Ductile Iron Manhole Cover A15:

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.

Manhole Cover

Q: Why does the precision casting factory not usually make iron castings?: Because it is too cheap, the design of materials is cast iron, generally do not have very high requirements.

Q: Is the cast steel a casting part?: Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.

Q: How to get rid of casting sand inside casting parts?: Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

Q: In theory, which is more expensive, forging parts or casting parts?: It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high

Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.: Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems

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: How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?: The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.

Q: Why do casting parts have air holes?: First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.

Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!: If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.

Q: How can the casting be free of trachoma?: 3, the gate is not facing sand core, flush sand core, will cause trachoma.
