QSD-B Series P·C Stone Molding Machine

This equipment is specially developed for municipal roads, landscape gardening, and building infrastructure projects as a high-end molding machine dedicated to imitation granite curbs and slabs, employing the industry’s advanced integrated high-pressure wet-material filtration plus vacuum-extraction molding process. The finished products achieve comparable density, strength, and surface texture to natural granite, offering both cost-effectiveness and environmental benefits, making it an ideal alternative to natural stone.

The core of the equipment utilizes direct high-pressure wet-material filtration molding technology, eliminating the need for lengthy curing or complex pre-processing steps typical of traditional methods. It boasts strong material adaptability, accepting cement, washed sand, stone powder, granite edge scraps, manufactured sand, and other materials, which are precisely proportioned and thoroughly mixed into a uniform wet mixture. During molding, the machine simultaneously performs high-pressure filtration and vacuum extraction, rapidly removing internal air and excess moisture, resulting in an extremely dense, pore-free, and delamination-free body. The finished products exhibit high density, extremely low water absorption, excellent compressive and flexural strength, smooth and refined surfaces, substantial texture, uniform coloration, and an appearance nearly identical to natural granite, giving them strong market competitiveness.

To meet diverse production needs—varying capacity, specifications, and strength—the equipment offers multiple adjustable molding pressures, including 250 tons, 350 tons, 550 tons, and 800 tons. Pressure output is stable, linearly increasing without impact, allowing flexible adjustment according to the thickness, size, and strength requirements of curbs and slabs, ensuring consistent quality across every piece. Under the combined action of high pressure and vacuum, the product’s internal structure becomes uniformly dense, with sharp, straight edges and smooth cross-sections, achieving high decorative effects without secondary polishing—perfect for municipal main roads, park scenic areas, upscale residential communities, commercial plazas, and other venues demanding exceptional aesthetics and durability.

The equipment features a scientifically designed and highly efficient power configuration, matching motors of various capacities such as 22KW, 25KW, 35KW, and 125KW, providing ample power while maintaining reasonable energy consumption, enabling energy-efficient operation even during high-pressure molding. The entire machine employs a heavy-duty, high-strength steel plate welded frame, subjected to aging treatment for enhanced rigidity, superior load-bearing capacity, long-term dimensional stability, and resistance to vibration and cracking, delivering outstanding stability. Host weights span multiple levels, including 8 tons, 18 tons, 25 tons, and 32 tons, ensuring a solid, steady chassis and smooth operation, capable of supporting 24-hour continuous high-intensity production with low failure rates and extended service life.

The molding rhythm is thoughtfully designed, with molding cycles controlled at 30–80 seconds per mold, automatically adjusting based on raw material moisture, product thickness, and pressure settings. This ensures stable pacing and controllable efficiency, accommodating both small-batch custom production and large-scale standardized mass production. The equipment boasts a high degree of automation, featuring simple operation: one-touch start, automatic filtration, automatic vacuum extraction, and automatic demolding, reducing reliance on manual labor and enhancing production safety and standardization.

Compared with natural stone mining, this equipment’s production process is free from blasting, minimal waste, and no environmental pollution, meeting green and low-carbon production standards while significantly reducing material costs. The finished products boast advantages such as high strength, wear resistance, freeze-thaw resistance, corrosion resistance, and fade resistance, with a service life far exceeding ordinary concrete curbs, and their aesthetic appeal can directly replace granite, making them widely applicable in municipal projects, road renovations, landscape construction, and beautiful countryside initiatives.

Overall, this equipment excels with its core advantage of integrated high-pressure wet-material filtration and vacuum-extraction molding, offering a complete range of models, flexible configurations, and stable performance. It efficiently produces highly realistic imitation granite curbs and slabs, serving as essential equipment for building material companies seeking to upgrade their products, expand into high-end markets, and enhance economic returns, providing higher-quality, more economical, and environmentally friendly stone alternatives for road and landscape engineering projects.
