Cast Iron Manhole Cover with High Quality from China Factory

Cast Iron Manhole Cover with High Quality from China Factory



Advantages



Good compressive, bending and impact strength, anti-corrosion, not rust, long service life  (at least 30 years).

The quality meets the same kinds cast ion manhole covers but the cost is 30% lower than.

Contain no metal and no recovery value, anti-theft.


Features



     1.High Intensity

It adopts macromolecule complex material and reinforcing steel bar moulded by high temperature and press at one time.

      2.Durable

Acid-alkali and corrosion resistance; anti-rust; insulation; weatherability; excellent anti-pressure capability.

     3.Unique  appearance

Rich colors;the cover is not sprayed in surface but painted in whole material so that the color can keep lasted.

     4.Competitive price

The price of compound manhole cover is lower than stipulated standard cast iron ones.

     5.Save mine resource

It is made by regenerated resin or regenerated plastic raw material, which save application of cast iron.

FAQ



1.Q: Are you factory ?
      YES!  We are a professional ductile iron &gery iron casting  Factory in China.
2.Q: How long can you make your quotation:
        Within 3 workdays after received your detailed product information
3.Q: Do you provide OEM Service?
       Yes, we provide OEM Service.
4.Q: What 's  your quotation element?
      Drawing, material, weight and quantity.

Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
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: The casting defects of pores, trachoma how to repair?
Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.
Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties
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: What is the difference between casting and stamping parts?
Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.
Q: Heat treatment process and purpose of casting parts
Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
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: The difference between sheet metal and casting parts
Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.
Q: ZGMn13 casting parts processing, with what knife head good?
The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger,
