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.

Delivery Detail of Ductile Iron Manhole Cover A15:
15 days after receiving the deposit.
- Q: What is the ejection angle of the die casting (Tan Gang)?
- Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
- Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- Annealing is needed to eliminate stress and refine grain
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
- The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
- 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, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
- Q: Where is the precision casting factory?
- Shandong, DongyingThe birthplace of precision casting
- 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!!
- Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
- 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!
- Q: In the design of casting steps and precautions, for casting design, we have what experience?.
- A: 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 reason is the bronze statue choking fire?
- The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
