manhole cover mould

We also often see the existence of manhole covers on urban roads. In the past, manhole covers were mostly made of cast iron, but this kind of material has many disadvantages, such as easy to break, easy to lose, easy to cause accidents, etc. Therefore, people began to study the replacement of cast iron products by polymer composite materials

Currently, most of the manhole covers are using SMC or BMC material to replace steel parts. The perfect property of SMC material can be reached 400-900KN, which can ensure a heavy truck to go cross. SMC manhole cover has the following advantages

• (1) SMC manhole cover has high strength, stiffness;
• (2) SMC manhole cover does not deform or break under heat and stress;
• (3) SMC manhole cover has high wear resistance and heat resistance;
• (4) SMC manhole cover has good molding process, low shrinkage rate and good dimensional stability;
• (5) SMC manhole cover has low molding pressure, simple manufacturing process, wide material sources and low price;
• (6) SMC manhole cover has non-recyclable performance, anti-theft (not recyclable).

Compression Mould process produces high strength, complex manhole cover parts in a wide variety of sizes. The manhole cover material charge is manually or robotically placed in manhole cover mould; the heated mould halves are closed, pressure can be available applied from 500T till 4000T at MDC workshop, cycle time ranges from one to five minutes, depending on part size and thickness. Features such as ribs, bosses, and inserts can be moulded in.
