Full Range QT5-15 Hollow Block Machine – 32 kW PLC Control

Matched System Design — The QT5-15 block machine manufacturer specifies machine, mould, pallet and handling together against the buyer’s actual block format rather than quoting isolated cycle speeds.

What "9600 Blocks per Shift" Leaves Out When Comparing Machines

A capacity number without its block format and cycle time is not a capacity number — it is a marketing headline.

I have watched buyers compare three quotations side by side and choose the one with the highest hourly figure, only to discover on site that the quoted rate assumed a small solid brick they never intended to produce. The block machine manufacturer you work with should state the mould count, block dimensions and cycle seconds behind every output claim. When a supplier quotes cycles per hour but omits the format, the real daily tonnage through your curing yard often falls well short of what the spreadsheet promised.

Placing the QT5-15 Within the Complete Machine Range

The QT5-15 occupies the mid-output tier, sitting above small workshop machines that run semi-automatic pallet handling and below high-capacity lines with full cubing and rack systems. For a buyer surveying options for a first or replacement plant, this tier offers automatic pallet feeding, material feeding, vibration and hydraulic demoulding as one integrated process without the capital jump to a fully stacked and cured end-of-line. The 1000 m² factory area requirement keeps the building footprint manageable while still accommodating a curing rack layout that matches the pallet output rate.

Where the Mid-Tier Machine Meets the Real Project Timeline

Construction contractors who need hollow blocks, pavers and solid bricks from one press find the QT5-15 range covers the formats that typically appear in a single housing or infrastructure project. The simple mould replacement system lets the crew switch from 400×200×200 mm hollow blocks in the morning to 200×100×60 mm rectangular pavers after lunch, keeping one machine busy across phases instead of leaving a specialised press idle. This format flexibility matters when the block machine manufacturer ships the unit to a site where the product mix evolves as the project moves from structural walls to external paving.

How Vibration Force and Hydraulic Pressure Shape Block Density

The 80 kN vibration force operating across a 0–60 Hz frequency range works together with the independent integrated hydraulic station to compact the mix inside the mould cavity. Platform vibration transmits energy through the 1100×550 mm pallet, and the hydraulic demoulding lifts the formed block without cracking green edges. If the vibration force were too low for a stiff, low-slump mix, the block would emerge with voids and fail the >15 MPa compressive strength target. If the hydraulic pressure were mismatched, the block would stick to the mould or crack during extraction — problems that show up only after the first production run.

The Cost of Ignoring Pallet Size and Curing Yard Layout

A buyer who selects a machine without checking whether the 1100×550 mm pallet fits the existing forklift tines and curing rack slots will spend the first week rearranging the yard or ordering new racks. Pallets that do not match the curing area force manual restacking, which negates the output advantage of the automatic tier and turns the end of each shift into a bottleneck. I have seen entire production lines sit idle while the crew searched for pallets that could survive the vibration cycle without splitting.

Why Procurement Starts with Format, Not Horsepower

Our machine, mould, pallet and handling components are specified as one matched system for the QT5-15, so the vibration force, pallet size and hydraulic pressure align with the block formats your market actually sells. Configuration is set against your local aggregate and mix design rather than a catalogue default — meaning the sand source and cement ratio you can actually obtain drive the setup. Mould design covers the formats in your quotation list, with custom drawings available when your market demands a profile outside the standard range. Automation level is selectable, letting you begin with the automatic QT5-15 and add stacking or cubing stations as volume grows. Installation support includes operator training so the crew can run format changes and daily maintenance from week one.

What to Prepare Before Requesting a Quotation

Send the target block formats with dimensions, the daily output you need per format, and a sample of your local sand or aggregate so the mix can be tested before the machine is configured. Confirm your site voltage, frequency and preferred PLC display language, along with the curing area dimensions and the forklift model already on site.

Frequently Asked Questions

Q: How do I verify the QT5-15 capacity for my specific hollow block size?
A: We provide a capacity calculation document that states the block dimensions, mould cavity count and cycle seconds behind every output figure. You compare that document against your daily target rather than relying on a single headline cycles-per-hour number that may assume a different format entirely.

Q: Where does the QT5-15 sit compared to semi-automatic and higher-output automatic models?
A: The QT5-15 is the mid-output tier with automatic pallet feeding, material feeding and hydraulic demoulding. It sits above semi-automatic machines that require manual pallet handling and below high-capacity lines with full stacking and cubing, matching buyers who need consistent automatic output without the capital outlay of an end-to-end line.

Q: What voltage, frequency and PLC language options are available?
A: Voltage and frequency are configured to your site supply, and the PLC display language is confirmed before the control cabinet is built. We lock these details in writing during the quotation stage so commissioning is not delayed by an electrical mismatch after the machine arrives.

Q: What plant footprint and supporting equipment do I need alongside the QT5-15?
A: The machine requires approximately 1000 m² of factory area, a concrete floor rated for the 5000 kg mass and vibration, a mixer matched to the 32 kW power envelope, and curing racks sized for 1100×550 mm pallets. Supporting equipment specifications are included in the line layout document.

Q: Can I start with the QT5-15 and add automation later?
A: The QT5-15 platform supports future additions such as automatic stacking and curing rack handling stations. The automation level is selectable at order, so you can begin with the core automatic press and expand the line as production volume and capital allow.
