The plastic mold of the through-hole manhole cover has low cost, good quality and low price, and strong competitiveness. We use waste residue as the main material, and the amount of waste residue can reach 30%-70%. This not only reduces the cost of raw materials, but also enjoys tax-free concessions, which reduces the cost of this series of products to the lowest level in the domestic industry. Each set of cast iron manhole covers more than 100 kilograms, even if the cost per kilogram of pig iron is more than 250 yuan, the cost of non-cast iron manhole cover is mostly more than 100 yuan, and this series of products cost 40 yuan per concrete type, composite type 50 yuan, stone molding 80 yuan, far lower than various products.
The through-hole manhole cover plastic mold products have excellent performance and good performance and price ratio. Although we use ordinary and cheap raw materials, the well covers are excellent in quality, excellent in overall performance, high in strength, long in life, light in weight, non-bounce, good in sealing, corrosion-resistant, color art, decorative, etc. Performance price ratio. This allows the product to enter the market at low cost and high performance.
Characteristics and advancement of three major products of Tongjing manhole cover plastic mold
1, super high strength. Cast iron manhole covers produced by other technologies have a bearing capacity of less than 15 tons of vehicles. Our products can withstand more than 30 tons of vehicles, of which the composite manhole cover can carry 40 tons, and the stone plastic manhole cover can carry 50 tons.
2, long life. The life of cast iron manhole covers is generally 3 years. There are non-cast iron manhole covers for 6 years, and the service life of our three major products is more than 15 years.
3, no recovery value, absolutely anti-theft. Among the three major products, the composite manhole cover does not contain metal, and the stone-plastic manhole cover and concrete manhole cover steel skeleton are less than 1/10 of the total weight of the manhole cover. There is not much value for theft. And because the strength of the manhole cover is extremely high, it is extremely difficult to remove this small point of steel from the manhole cover. Therefore, the thief does not steal.
4, super lightweight. The cast iron manhole cover is 130 kg per set and 220 kg heavy. The normal type of this product is only 50 kg, and the heavy duty is only 90 kg. It is only 40% of the cast iron manhole cover, which is one quarter lighter than other non-cast iron manhole covers.
5, the manhole cover does not bounce, no noise. The vehicle does not bounce, does not slip, has no impact noise pollution, and is environmentally friendly.
6, good sealing, effective anti-virus. This product has good sealing performance to the well, and the harmfulness caused by harmful gas and gas leakage in the sewage pipe is greatly reduced, which can improve the safety of use.
7, not easy to rust, insulation and corrosion resistance. The steel frame of this series is enclosed inside, not in direct contact with the atmosphere, the rusting opportunity is greatly reduced, and the formulation of this product enables the steel bar to automatically generate passivation anti-rust film, which can effectively prevent rust and prolong the service life of the product.
8, color art, good decoration. The three series of products are all in color art. The patterns can be designed according to local needs and characteristics. They are beautifully decorated and installed on the road, such as blooming flowers, which are pleasing to the eye.
