BMC polymer resin molded manhole cover

Product Introduction

The new BMC polymer resin molded composite manhole cover produced by our factory adheres to the concept of "green and environmental protection", uses unsaturated resin, glass fiber and other chemical raw materials, supplemented by steel reinforcement, and is compounded under high temperature and high pressure.

Product Benefits

1. Anti-theft

The materials used in this product have no recycling value and therefore cannot be stolen, fundamentally eliminating the phenomenon of urban traps and road black holes and protecting people’s lives and property.

(ii) Lightweight, easy to use, and affordable

It uses high-strength composite materials as raw materials, is convenient and practical, weighs about half of cast iron products, is easy to transport and construct, is cheaper than cast iron manhole covers, and is rapidly promoted.

(III) High and low temperature resistance, corrosion resistance, and aging resistance

The raw materials used have stable performance. After being tested in accordance with the national standards for high and low temperature resistance, corrosion resistance, and aging resistance for related products, the product performance indicators meet the standards and have a long service life.

(IV) Large payload and no impact noise

This product has both the strength of cast iron manhole covers and the toughness of cast iron manhole covers, with high performance and large bearing capacity. This product is formed by high-temperature die-casting, with a small gap between the cover and the seat, which overcomes the problem of manhole covers "running, jumping, and making noises", and improves road traffic capacity and driving.

(V) Strong color plasticity

The products can be matched with colors, plate-making and typing according to customers' requirements, and the designs are exquisite and scientific.

Product Application

It is suitable for streets, industrial parks, residential areas, city squares, underground garages, colleges, factories and mines, farms, communications, fire protection, gas, chemical industry, water supply and drainage, and all roads or sites with underground facilities, as well as shaft exits and fertilization and maintenance pools for trees, flowers and plants.

Product applicable units

Water supply companies, municipal companies, real estate companies, gas companies, China Unicom, Netcom, China Mobile, China Tietong, power companies, factories and mines, parks and schools, etc.

SMC polymer resin molded manhole cover

Product Introduction

SMC is a raw material for sandwich molding. The core material is short-cut untwisted coarse yarn, impregnated with polyester resin paste, and covered with polyethylene film on the upper and lower sides. When used, it is added to the heated mold, pressurized and maintained for the required time, and then the product can be demoulded to obtain the product.

Product Advantages

1. SMC resin material has all the advantages of BMC material.

Second, SMC has very good formability, which is very suitable for large-size products and products with complex shapes and structures, and the size of the molded parts is stable.

3. High productivity, suitable for batch production.

4. The surface quality is good and can meet the A-level surface requirements.

5. The colors are diverse and bright.

6. The product has high strength and strong toughness.
