QT5-15 Block Machine for Hollow Block | Full Range

Matched System Specification — the QT5-15 is configured as a complete press, mould, pallet, and handling package rather than assembled from separate suppliers, so cycle time and output figures reflect the actual block format you plan to produce.

What "1800 Pieces per Hour" Actually Means for the QT5-15 Block Machine

Output only holds true when the block format, cycle time, and mix design are stated together.

I have watched buyers receive a QT5-15 block machine for sale brochure quoting a single hourly number, then discover on commissioning day that their chosen hollow block format runs a longer cycle than the catalogue assumed. The 1800 pcs/h figure applies specifically to 400×200×200mm hollow blocks at a 16-20 second cycle with 5 pieces per mould. Switch to a 400×150×200mm hollow block and the realistic rate shifts to around 1300 pcs/h at 6 pieces per mould with a 15-20 second cycle. Pavers tell a different story again. Without format-level capacity documentation, daily planning becomes guesswork [NEED_CITE: capacity calculation standards for concrete block production lines].

Positioning the QT5-15 Within the Stationary Block Machine Range

The QT5-15 occupies the mid-tier of our stationary block machine lineup. Below it sits the semi-automatic range suited to smaller workshops with lower capital outlay and manual pallet handling. Above it, high-capacity automatic lines push larger pallet sizes and shorter cycles for buyers who need maximum throughput from day one. The QT5-15 block machine bridges these tiers, offering fully automatic PLC-controlled operation at a power draw of 26.5 kW — substantial enough for consistent production yet manageable for plants that are not yet running three shifts.

Where the Automation Tier Meets Your Growth Path

Buyers often start with a semi-automatic press and add automatic pallet feeding, stacking, and cubing later. The QT5-15 is designed within the same platform family, meaning the mould interface, pallet size, and hydraulic connections remain compatible as you move through the range. This matters when a distributor evaluates the full product family for a regional market — stocking one pallet size and one mould mounting standard across tiers reduces inventory complexity. The block machine manufacturer configures each tier so the jump from semi-auto to fully automatic is a module addition, not a full machine replacement [NEED_CITE: modular automation upgrade paths in block making equipment].

Reading the Specs That Decide Daily Output

Platform vibration at 2800–4500 r/min works together with 21 MPa hydraulic pressure to compact the mix. Higher frequency suits fine aggregate and paver faces; lower frequency with sustained pressure fills deep hollow block cores. The 1100×550 mm pallet size determines how many blocks fit per cycle — five for a standard 400×200×200mm hollow block, sixteen for an S paver. Molding cycle ranges from 15 to 25 seconds depending on format complexity and mix workability. Overall dimensions of 7400×1950×2800 mm set the press footprint, but the full line length extends once you add mixer, pallet feeder, and stacking stations. Hydraulic demolding lifts the mould box cleanly, reducing edge chipping on interlocking profiles and colored paver surfaces.

The Cost of Skipping Format-Level Configuration

A buyer once ordered a stationary block machine rated at a blanket hourly capacity and assumed any mould would deliver the same output. When the first custom interlocking block mould arrived, the cycle stretched beyond the quoted figure because the vibration frequency and hydraulic hold time had never been matched to that specific geometry. Production fell short, the curing rack backed up, and pallets piled on the floor because the stacking station was specified for a faster cycle. These mismatches are not equipment failures — they are specification gaps that surface only after the line is running [NEED_CITE: common causes of block plant output shortfalls].

Why Source the QT5-15 Through Shiyue

Block machinery is our single focus, so the QT5-15 arrives with machine, mould, pallet, and handling specified as one matched system. Configuration is set against your actual mix design and local aggregate rather than a catalogue default. Mould design covers the formats your market sells, including custom drawings reviewed before production. Automation level is selectable — you can take the QT5-15 in semi-automatic trim now and upgrade later within the same platform. Installation support includes operator training on the PLC interface so your crew is self-sufficient from the first week.

Before You Request a Quote

To size the QT5-15 correctly within our range, share the block formats your market currently sells and the daily volume you target for each. Confirm your local raw materials — aggregate type, sand gradation, and cement availability — so the mix can be matched before the mould is built. Let us know your site voltage and frequency, plus the control language your operators read, so the PLC is configured before the machine leaves the factory.

Frequently Asked Questions

Q: Where does the QT5-15 sit compared to semi-automatic and higher-capacity models in the range?
A: The QT5-15 is the mid-tier fully automatic stationary block machine. Below it, semi-automatic models suit smaller workshops with manual pallet handling. Above it, high-capacity lines use larger pallets and shorter cycles. The QT5-15 offers full PLC automation at a 26.5 kW power level, bridging entry-level and top-tier investment.

Q: What is the realistic daily output per block format on the QT5-15?
A: Output depends on format. For 400×200×200mm hollow blocks, the rate is 1800 pcs/h at a 16-20 second cycle. For 400×150×200mm hollow blocks, expect 1300 pcs/h at 15-20 seconds. S pavers at 225×112.5×60mm run around 3700 pcs/h at 15-17 seconds. Daily totals depend on shift length and line uptime.

Q: What plant footprint and supporting equipment does the QT5-15 require?
A: The press itself measures 7400×1950×2800 mm, but the full line includes mixer, pallet feeder, and stacking equipment. Pallet size is 1100×550 mm, so curing racks and forklifts must accommodate that dimension. We provide a line layout showing every station before order confirmation.

Q: Can I start with a semi-automatic QT5-15 and add automation later?
A: Yes. The QT5-15 platform supports a selectable automation level. You can begin with semi-automatic operation and add automatic pallet feeding, stacking, or cubing modules later. The mould interface and pallet size stay the same, so existing tooling carries over without replacement.

Q: What investment level does the QT5-15 tier represent in the range?
A: The QT5-15 sits between entry-level semi-automatic machines and high-capacity automatic lines. It offers full PLC control and hydraulic demolding at 21 MPa for buyers who have outgrown manual operation but do not yet need maximum throughput. Stepping to the next tier adds larger pallets and higher cycle speeds.
