Polymer-sand sewer manhole covers are an excellent alternative to traditional cast-iron products. Comparative tests show that they are twice as strong and 1.5 times lighter, while their service life is virtually unlimited. Color pigments offer broad design possibilities for urban spaces, and the pigments are resistant to sunlight and adverse weather conditions. Steady demand for this type of polymer-sand product is driven by the following advantages:
- long service life;
- lower weight than cast-iron alternatives;
- a wide range of colors;
- resistance to temperature and humidity fluctuations;
- chemical resistance, including resistance to de-icing agents and disinfectants;
- low thermal conductivity, which prevents freezing;
- no interference with remote data transmission from monitoring and metering devices;
- of no interest to scrap-metal collectors.
Market-demand analysis and economic calculations demonstrate the potential of polymer-sand manhole-cover production. The key indicators significantly exceed average standard values for various industries. Minimal space and staffing requirements, growing demand, and relatively modest investment make polymer-sand manhole-cover production highly attractive. Using plastic waste as a raw material also significantly reduces production costs while helping solve the problem of plastic disposal.
Ivanovo Mechanical Plant offers unique equipment for quickly launching the production of sewer manhole covers and other polymer-composite products. Our own developments are based on original engineering solutions, proven technology, and patented formulations. All processes are highly automated, reducing the required operating staff.
The standard configuration includes:
- dosing units;
- a shredder for preparing raw material from recycled plastic;
- a melting and heating unit;
- a press;
- molds.
All equipment is selected according to the customer's specific requirements.
