The whole machine main frame is integrally welded by thick 12cm×12cm square steel supplied by Laigang and Jinggang, two top domestic steel manufacturers in China. The thickened square tube structure greatly improves the overall rigidity, torsion resistance and impact resistance of the equipment. During long-term continuous high-frequency vibration and hydraulic stamping production, the frame will not deform, bend or crack, which effectively extends the whole service life of the block machine. Unlike thin steel frames used by low-cost small manufacturers, this robust frame can withstand long hours of heavy load production without structural aging.
The hydraulic system adopts original Calyca hydraulic components imported from Taiwan, a well-known professional hydraulic brand in Asia. Compared with ordinary domestic hydraulic accessories, Calyca hydraulic valves, oil cylinders and oil pumps feature stable pressure output, small pressure fluctuation and low internal leakage. The hydraulic oil tank is integrated on the main machine, with complete sealing and dustproof design, which avoids hydraulic oil pollution. The whole hydraulic circuit runs smoothly, reduces sudden shutdown failures caused by unstable oil pressure, and supports 24-hour non-stop continuous industrial production.
The QTF3-20 semi-automatic concrete block machine abandons the traditional single external vibration motor driving mode, and adopts an integrated built-in vibration box as the vibration source. The vibration force can be evenly transmitted to the whole supporting pallet without local vibration dead zones. The vibration box has good heat dissipation and dust isolation performance; the motor inside is not easy to burn out under long-time high-frequency operation, greatly cutting down the frequency of motor replacement and daily maintenance cost.

The equipment is equipped with a full platform vibration system, with a maximum exciting force of 50KN and a vibration frequency reaching 4500 times per minute. In the molding process, high-frequency uniform vibration cooperates with 16Mpa hydraulic pressing force at the same time, so all concrete raw materials inside the mould can be fully vibrated and compacted. The produced bricks and blocks have uniform internal density, smooth surface, no loose edges, hollow cores or honeycomb holes, and the compression strength of finished products fully meets national and international building material standards.
A complete feeding, vibration and pressing molding cycle only takes 20 to 25 seconds. Fast circulation molding greatly improves the hourly production capacity of the equipment. Under standard continuous operation, the block machine can stably produce thousands of finished blocks per shift, which can fully meet the medium-scale production demands of brick factories, construction material processing plants and waste resource recycling enterprises. The small matched pallet size of 680mm×550mm further reduces the extra procurement cost of supporting pallets for customers.
The QTF3-20 semi-automatic block machine is pre-installed with an independent color material feeding system as standard configuration, which can realize separate feeding of surface color mortar and base concrete material in one molding procedure. Besides ordinary hollow blocks and solid standard bricks, manufacturers can produce colorful interlocking pavers, garden landscape bricks, curb stones, grass planting bricks and slope protection bricks. Multiple product categories help buyers expand market business and increase profit sources without purchasing extra separate color feeding equipment.
The semi-automatic concrete block machine has extremely high tolerance for mixed raw materials. Available production materials include crushed stone, river sand, cement, coal fly ash, coal cinder, mineral slag, coal gangue, expanded perlite and other industrial solid wastes. Enterprises can replace a large proportion of expensive natural aggregate and cement with local waste residues, significantly lowering overall raw material expenditure. Meanwhile, the production mode of recycling industrial waste conforms to global environmental protection and circular economy policies, helping factories obtain relevant environmental assessment qualifications and policy subsidies.
One set of standard hollow manganese steel mould is delivered together with the machine for free. All customized moulds adopt wire cutting processing and carburizing heat treatment technology. The finished mould has ultra-high dimensional accuracy and outstanding wear resistance, and will not wear or deform after long-term high-frequency friction with concrete materials. Customers only need to replace different moulds according to market demand, and a single host can switch the production of dozens of different specifications of building blocks, realizing multi-purpose of one machine and reducing investment in multiple forming equipment.

A complete matching electric control box is equipped on the side of the main machine, pre-programmed with standardized automatic production logic programs. The control system supports automatic circulation of feeding, vibration, pressing and demoulding. It also carries built-in fault self-check modules, which can automatically identify abnormal signals of vibration, hydraulic pressure and feeding, and display fault prompts intuitively. Ordinary workers without professional electrical maintenance background can quickly judge and solve simple equipment faults without hiring senior technical staff all year round.
The operation logic of the equipment is clear and straightforward. New operators only need short-term simple training to independently complete full-day production operation. All wearing parts such as vibration box components and hydraulic seals are designed for quick disassembly and replacement, and daily cleaning and lubrication work are convenient, which greatly saves labor time spent on equipment maintenance every day.
The overall dimension of the QTF3-20 main machine is 5990mm×4260mm×2620mm, with a total net weight of 3500KG. The compact overall structure will not occupy excessive space during ocean transportation. When matched with supporting vertical mixer, 8m belt conveyor and automatic block stacker, the whole complete production set can be fully loaded into one standard 20-foot container, which effectively reduces international ocean freight cost and simplifies cross-border logistics arrangement for overseas importers.
The manufacturer provides a full one-year warranty service for the QTF3-20 semi-automatic block machine, counting from the date of complete installation and commissioning at the buyer’s local factory. Within the warranty period, all standard spare parts damaged due to original manufacturing quality problems can be replaced free of charge by the supplier. Professional online technical guidance is provided all the year round to solve installation, debugging and production failure problems remotely, reducing the customer’s later operation risk and maintenance capital investment.
