Nowadays, more and more companies are using SMC composite materials to produce manhole covers. Today, PHP will talk about the advantages of SMC manhole covers made by compression molding process.
The weight of SMC manhole cover is only one fourth to one third of iron cover, so it is convenient to transport, install and repair.
SMC manhole cover uses high molecular synthetic material with steel reinforcement framework and is formed by compression molding process with high temperature and high pressure. The maximum testing result of bearing tonnage is larger than 40 ton.
SMC products have low recycle and reuse value so SMC manhole cover can avoid being stolen; what’s more, it has self-locking property, the black hole accident in cities can be completely eradicated.
SMC materials are natural anti-corrosion, so they have technical and economic advantages for manhole covers used in acidic, alkaline, salty, polluted environments.
Oil gas leakage can be effectively avoided so as to reduce the accident rate.
SMC manhole cover can be used for more than 30 years.
SMC manhole cover has exquisite surface pattern with customized company logo, nice and durable.
Since the product is formed by high temperature compression molding, so the joint gap of cover frame is small. Therefore, the problem of skipping, jumping and noise occurred in cast iron or cement manhole covers can be overcome and the road capacity and drive comfort can be improved.
PHP is specialized in manufacture SMC hydraulic press which is applied in fields like automotive lightweight, construction and building, rail traffic, low-voltage electrical and communication. If you need to make SMC manhole covers, welcome to reach us:
