Features of DI Manhole Cover 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.

- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
- Q: Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?
- The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot
- Q: What is the difference between forging parts and casting parts?
- The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.
- 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: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q: What should I pay attention to when designing a casting structure?
- 1 of the casting in metal mold cooling was faster than sand, metal type and let, thus casting in metal mold casting, casting stress generated in the ratio of sand casting to crack tendency is also large, but also prone to misrun and cold lap, white (for casting casting). Defect. Usually: (1) in the prevention of metal casting casting crack aspect should pay attention to the following problems: the structure of A in wall thickness, wall transition and connection to the ease, corner fillet appropriate requirements such as should be more strict than sand casting; B should be connected vertically connected with the wall to tilt C; for the weak parts of the structure should be set to strengthen ribs, bosses, to prevent casting; D should minimize the obstacle free shrinkage of the boss, casting rib, flange and other prominent part; E in the casting arrangement of ribs, but also should consider its influence on the casting shrinkage.
- Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- It has something to do with the size of your work, and it has a lot to do with the blade you're using right now.
- 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?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
- 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: How to solve casting defect casting?
- Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire
