QT4-15 Automatic Concrete Block Molding Machine

Product Description

<h2>What the QT4-15 Is Built For</h2><p>The QT4-15 is an automatic concrete block molding machine aimed at small and mid-sized block works that need reliable daily output without a large crew. It brings mechanical, hydraulic, and electrical control together in one unit, so a single operator runs what used to need several workers. Investment cost stays moderate while output stays steady, which suits standard brick factories and municipal building material suppliers.</p><h2>Vibration Plus Hydraulic Pressing</h2><p>The machine forms blocks with a vibration and pressure process. High frequency vibration spreads the mix and settles it inside the mold cavity, then hydraulic pressure compacts it into a dense, uniform mass. A full cycle takes 15 to 20 seconds. Each mold carries 26 standard bricks, so one eight hour shift can turn out roughly 37,440 to 49,920 bricks. The same cycle also runs hollow blocks and paving bricks once the mold is changed.</p><h2>Control and Line Integration</h2><p>A PLC with a touch screen interface manages the whole sequence. The operator sets parameters, monitors the run, and reads fault alarms and diagnostics from the panel instead of walking the line. The machine handles material distribution, vibration, pressing, demolding, and brick discharge on its own. It connects with batching machines, mixers, conveyors, and automatic palletizers, so a plant can assemble a complete automatic line and cut manual handling.</p><h2>Frame, Drives, and Running Costs</h2><p>The body is a high strength welded frame built to hold up under constant vibration and high pressure. Hydraulic components and vibration motors come from established makers, which keeps motion smooth and the failure rate low. Wear parts are simple to reach and swap, so maintenance stays predictable across a long production schedule. Total installed power is 22.9 kW.</p><h2>Technical Parameters</h2><p>The main figures are straightforward: total power 22.9 kW, excitation force 68 kN, molding pressure 25 MPa, and host weight 6,200 kg. The host measures 6,200 x 2,350 x 2,700 mm and takes trays of 850 x 560 x 20 mm. The material distribution motor is rated 2.25 kW. These numbers describe what the machine draws and what it pushes into the mold, so a plant can size batching and mixing equipment to match.</p><h2>Where It Fits</h2><p>Plants use the QT4-15 for standard concrete bricks, hollow blocks, and paving bricks, and it suits projects that mix these products in the same week. It serves municipal material suppliers, rural housing programs, and contractors who want one machine that can switch molds and keep the yard busy through the season.</p>
