Block Making Machine Price Bands by Output Tier and Drive

A block making machine price sits inside a band, not at a single point, and the band follows the output tier. Four numbers fix that band before freight and duty enter the picture: pallet size, machine weight, installed power and vibration force. They climb together. A QT4-15 runs at 22.9 kW and weighs 6,200 kg, and it moulds on an 850 x 560 mm pallet. A QST1800 runs at 104 kW and weighs 34 t, on a 1,400 x 1,400 mm pallet. This page walks the ladder step by step, including the parallel static press line, and shows how to spot a small frame being sold as a large production line.

1. The bottom step: what a QT4-15 actually buys

Start where the ladder starts. A QT4-15 carries 22.9 kW of installed power, weighs 6,200 kg, and delivers 68 kN of vibration force on an 850 x 560 x 20 mm pallet, on a 25 MPa hydraulic system. Cycle time is 15 to 20 seconds, for two pallets of work per minute on a good mix. That combination is honest for a plant selling a few hundred blocks a day into a local market, and it is the cheapest complete moulding unit we build.

The limits at this step are structural, not commercial. At 6,200 kg the frame cannot carry a 1,400 mm pallet, and at 68 kN of force the work stays on the non-structural side: garden walls, kerbs and thin partitions. The bottom step is therefore not a stripped version of the top step. It is a different machine class with a smaller pallet, and its price is lower because of that geometry, not because a salesman removed parts from it.

2. The middle three steps: 34.4 kW to 57.6 kW

The middle of the ladder is where most export projects land. QST6-15 holds 34.4 kW and 12 t with 68 kN of vibration force on a 980 x 680 mm pallet. QST8-15 steps up to 44.9 kW and 14 t, 95 kN of force, a 980 x 860 x 22 mm pallet, and a hydraulic system that holds 31.5 MPa instead of 25 MPa. Rated output is 90,000 standard bricks in an 8 hour shift.

QST1200 is the third step of the middle group: 57.6 kW, 17 t, 150 kN of vibration force, a 1,350 x 880 x 25 mm pallet, and 120,960 standard bricks in 8 hours. Between QST6-15 and QST1200 the cycle stays inside the 15 to 25 second band, so the extra output comes from pallet area and from the force behind it, not from a faster cycle. That is the structural reason you pay more without the machine running any quicker.

3. The top step: QST1500 and QST1800

QST1500 carries 69.1 kW and 20 t, with 220 kN of vibration force on a 1,350 x 1,150 x 30 mm pallet. QST1800 carries 104 kW and 34 t, with 280 kN on a 1,400 x 1,400 x 30 mm pallet, and it reports 220,000 standard bricks in an 8 hour shift. Both hold 31.5 MPa and run a 15 to 25 second cycle.

At this level the price stops describing the moulding unit alone. QST1800 occupies 15,500 x 5,500 x 3,200 mm of floor, while QST1500 and QST1200 occupy 11,500 x 4,550 x 2,800 mm. The stacker on the two largest machines draws 3.7 kW, against 3.0 kW on QST8-15 and QST6-15. Foundations, crane access and building height join the bill at the top step, and none of those three appears in a machine-only quotation.

4. The parallel ladder: static presses from QS600 to QS1500

Block is not the only product, and vibration is not the only drive. The static hydraulic line runs from QS600 to QS1500, all of them at 31.5 MPa, with a main cylinder that grows from 450 mm to 720 mm in bore and installed power from 46.9 kW to 108.2 kW. Machine weight moves from 23 t to 43 t across the same span, which is the clearest sign of what the buyer is paying for.

Mould output shows the geometry of each step. On a 200 x 100 x 60 mm paver, QS600 forms 16 pieces per mould and QS1500 forms 40. On a 390 x 190 x 190 mm hollow block the count runs 5 on QS800, 10 on QS1000 and 12 on QS1500. A double-direction press moves the money again: QS1500 goes from 88.4 kW and a 20 to 25 second cycle to 108.2 kW and 18 to 22 seconds.

5. Four numbers that expose a small frame sold as a big line

Ask for four numbers and put them side by side: pallet size, machine weight, installed power and vibration force. In our own range, a 68 kN machine weighs between 6,200 kg and 12 t, a 95 kN machine weighs 14 t, a 150 kN machine weighs 17 t, and a 280 kN machine weighs 34 t. Steel and force move together, because the frame, the columns and the bearings absorb the vibration, and the motor only starts it.

So when a quotation offers 220 kN of vibration force on a 12 t machine, or a 1,400 x 1,400 mm pallet under 44.9 kW, one of the four figures is wrong. A 280 kN machine on a 1,400 mm pallet, with 104 kW behind it and 34 t of frame, is a set that agrees with itself. A small frame sold as a large line always fails one of these four checks, usually on weight, because weight is the most expensive number to invent.

6. Landed cost: where the equipment price stops being the total

Equipment is one line of a longer budget. In the plants we see, machinery lands around 40% to 55% of the total build, and the rest is foundation, building, curing yard, pallets and the power connection. On top of the machine price, add landed cost for sea freight, duty and inland transport, commonly +15% to +40% depending on the destination and the number of containers.

Published whole-machine bands for cement block machines run from $30,000 to $300,000, and a small machine and a large one can sit more than 100 times apart once capacity is counted. Those two published figures bracket a budget honestly before the configuration is fixed. They are not a quotation. QST8-15 and QST1800 do not share a price, and neither do a single-direction and a double-direction press of the same size.
