The Cadona is a fully automatic, hydraulic concrete block injection molding machine with PLC control. It is designed to produce hollow and solid blocks, color paving blocks and curbstones with high output and easy operation.
Model: QTJ4-18. Motor power: 20.5 kW (power distribution suggested 40 kW). Weight: 5,000 kg. Overall size: 3700 × 2100 × 2700 mm. Forming cycle: 20–25 seconds. Vibrating force: 60 kN. Down pressure: 4–7 tons. Pallet size: 850/880 × 550 × 20 mm.
It can use cement, concrete, sand, fly ash, construction waste, slag and mountain flour (local stone powder).
Typical proportions: cement 8%–10% of the mix. A commonly used approximate ratio by volume is cement : sand : stone ≈ 1 : 4 : 5.
It can produce hollow and solid blocks, color paving blocks and curbstones in a variety of sizes. Common sizes listed include 400×200×200 mm, 400×150×200 mm, 400×100×200 mm, 400×250×200 mm and many smaller formats; molds can be changed to make other sizes and shapes.
Example hollow block weights from the specification: 400×200×200 mm ≈ 17 kg; 400×150×200 mm ≈ 13.5 kg; 400×100×200 mm ≈ 10 kg.
Capacity depends on block size and number of cavities per mould. Typical examples from the machine data: 400×150×200 mm — 5 pcs/mould, ~1,200 pcs/hour, ~9,600 pcs/8 hr; 400×200×200 mm — 4 pcs/mould, ~960 pcs/hour, ~7,680 pcs/8 hr; 400×100×200 mm — 7 pcs/mould, ~1,680 pcs/hour, ~13,440 pcs/8 hr; 400×250×200 mm — 3 pcs/mould, ~720 pcs/hour, ~5,760 pcs/8 hr. (Actual output varies with mix, cycle time and operator efficiency.)
Recommended installation area: 2,600–3,300 m². Workshop area: ~80 m². Raw material/workshop area: ~400 m². Office: ~50 m². Staff: 5–6 people. Power distribution: ~40 kW available. Water consumption: about 5 tonnes/day.
The spec indicates around 1,500 pallets are required for continuous operation. Pallet size is 850 or 880 × 550 × 20 mm (depending on tooling).
Yes — the machine is equipped with a PLC control box for automated cycles and easy operation. Controls are intended to be user-friendly, but operator training is recommended.
Yes. The machine specification lists construction waste and slag among acceptable materials. Proper processing and grading of recycled materials is important to ensure block strength and consistent quality.
Regular maintenance includes checking hydraulic oil and filters, vibration system inspection, greasing moving parts, checking pallets and moulds for wear, and monitoring electrical/PLC connections. It's advisable to stock wear parts such as spare pallets, seals, liners, vibration elements and common hydraulic components.
Most suppliers of this type of machinery provide installation, commissioning and operator training — confirm service scope with the seller. Professional installation and initial training are recommended to reach optimal performance quickly.
Yes. Moulds can be customized for different block sizes, patterns and colors. Color paving blocks require pigment added to the mix; discuss specific customization, tooling lead times and costs with the supplier.
