CONCRETE PRODUCTS & CAST STONE116 CPI %u2013 Concrete Plant International %u2013 5 | 2025 www.cpi-worldwide.comIn concrete paving block production, precision and quality are essential in ensuring flawless products and minimizing production costs. A major advancement in the industry is the integration of advanced technologies such as intelligent quality control systems. This technology not only improves efficiency but also enhances control over production quality.Board weighing for greater precisionThe weighing of production boards is a crucial step in ensuring production accuracy. Before machine processing, the production board is weighed to determine the weight of the empty board. This weighing process takes place during the idle time of each cycle, ensuring that the flow of production remains uninterrupted. After processing, the weight of the product is measured on the walking beam conveyor, enabling precise determination of product quantities and continuous monitoring of production performance. This measurement also takes place during the cycle%u2019s idle time, keeping the production process efficient.Automatic quality control with AIThe new automatic quality control system Frima AQC (Automatic Quality Control) was specifically developed for paving block / paving slab production and is based on artificial intelligence. It can be easily integrated into existing production lines and works with equipment from any manufacturer without requiring modifications. The system operates on the wet side of the production line following the block-making machine and ahead of the elevator.Using a high-precision laser scanner and a camera, the products are continuously monitored. The laser measures product height with an accuracy of 0.5 mm, while the camera system detects surface defects such as cracks, stains, inclusions, or depressions. These defects are displayed in real time on the operator%u2019s screen, with deviations highlighted in colour, allowing the operator to intervene immediately and prevent the production of defective products.Advantages for productionThe Frima AQC system can offer the following advantages:%u2022 Reduction of production lossesFast error detection helps minimizing the number of defective products.%u2022 Improved product qualityDefective products are detected immediately, increasing the overall quality of the final products.Optimizing production quality with innovative technology %u2013 new systems for paving block productionFrima GmbH & Co.
