Description
Mould format matched to your actual sales mix — output capacity on this QT6-15 is calculated per block size and cycle time, not reduced to a single headline figure that ignores format changeovers.

What "1080 Pieces per Hour" Actually Means on the QT6-15
Every capacity figure on this page is tied to a specific block format and moulding cycle, because a single number without that context is how projects run into delays.
I have sat through commissioning meetings where the buyer signed a contract on a headline cycle rate, then watched real output fall to half when the block format changed or the local sand carried more clay than the factory test assumed. The hollow block making machine specifications you evaluate should always name the block dimensions, the cycle seconds, and the mould cavity count behind each hourly rate. Without those three numbers together, you cannot plan curing racks, pallet circulation, or shift staffing. [NEED_CITE: block output calculation standards by format and cycle time]
Platform Vibration Tuned to Your Mix Design
The QT6-15 uses platform vibration adjustable from 0 to 60 Hz with a rated force of 45 kN. This is the parameter that determines whether your local aggregate compacts fully before the hydraulic head finishes its stroke. A high-clay river sand needs a different frequency window than washed crushed granite, and getting this wrong shows up as inconsistent block strength across the pallet.
Mould Selection and Cycle Time by Format
Hollow block making machine specifications mean little without the matching mould inventory. The QT6-15 covers cavity counts from 6 per mould on the 400×200×200 mm hollow block up to 32 per mould on the 240×115×53 mm solid brick. Paving formats like the 200×100×60 mm rectangular brick run on a longer 20–25 second cycle because surface finish tolerance is tighter. A technical buyer planning daily output needs these per-format numbers to size the curing yard and pallet return loop. [NEED_CITE: paving block cycle time versus surface finish requirements]
Reading the Specs That Matter on Site
The independent integrated hydraulic station sits isolated from the main press vibration, which keeps seal wear and valve response consistent across a full shift. The 880×850 mm pallet size must be cross-checked against whatever curing racks and forklifts the buyer already has — ordering a machine whose pallets do not match existing handling equipment causes bottlenecks that no amount of press speed can fix. The PLC touch screen controls the moulding sequence, but the display language and electrical voltage must be confirmed before the machine enters production, not after it arrives at the port. The 45 kN vibration force and hydraulic pressure work together: vibration settles the mix into the mould cavity while hydraulic pressure sets the final density, and both must match the buyer’s actual mix proportions.
When the Wrong Configuration Reaches the Site
A pallet size chosen without regard to the curing area means blocks are stacked by hand before they gain initial set strength. Voltage and frequency confirmed too late delay commissioning by weeks while transformers or motor rewinds are arranged. A mould change procedure that takes most of a shift cancels out the format flexibility the buyer paid for in the first place.

Why This Machine Is Configured Before It Is Quoted
Block machinery is the single production focus here, so the press, mould, pallet, and handling equipment are specified as one system rather than assembled from unrelated suppliers. The hollow block making machine specifications are set against the buyer’s confirmed mix design and target block format, not a catalogue default. Mould design covers the formats the buyer’s local market actually sells, with custom drawings when standard cavities do not match. Automation level is selectable, meaning a semi-automatic start can be upgraded later without replacing the press. Installation support includes operator training so the crew understands mould change procedure and cycle adjustment from day one.

What We Need to Configure Your QT6-15
Send the target block formats your market sells, the daily output you need per format, and a sample or description of your local aggregate and sand source. Confirm the site voltage, frequency, and preferred PLC display language so the control panel is built to match. If you have existing pallets, curing racks, or forklifts, share the dimensions so the 880×850 mm pallet system is verified against your handling setup before the quotation is finalised.
Frequently Asked Questions
Q: How is capacity calculated per block format on the QT6-15?
A: Each output figure pairs a specific block dimension, mould cavity count, and moulding cycle in seconds. For example, the 400×200×200 mm hollow block runs 6 cavities per mould at a 15–20 second cycle, giving 1080–1440 pieces per hour. Paving formats use a longer cycle for surface finish.
Q: How do I match vibration force to my local aggregate?
A: The 45 kN platform vibration is adjustable across 0–60 Hz. High-clay or fine-graded materials need a different frequency window than coarse crushed stone. We configure this against your confirmed mix design before dispatch.
Q: What mould formats are included and how long does a change take?
A: The format list covers hollow blocks, solid bricks, and pavers from 400×200×200 mm down to 225×112.5×60 mm zigzag. Mould change time depends on the specific system fitted and must be confirmed during the quotation stage.
Q: How do I confirm voltage and PLC language before production?
A: Both are locked in during the configuration proposal stage, documented in writing, and verified against the buyer’s local electrical standard. This prevents commissioning delays when the machine arrives at site.
Q: Does the 880×850 mm pallet fit my existing curing racks?
A: Pallet dimensions must be cross-checked against your curing area layout and forklift capacity. We verify this during the line design phase so pallet circulation matches your site handling equipment.
