QT5-15 Concrete Brick Machine for Hollow Block – Technical Guide

Description

Mould-First Engineering — the QT5-15 block machine is sized to the buyer’s exact block format, with every cycle time and output figure traced back to a named mould and a stated pallet dimension.

What "7200 Pieces per Day" Actually Means When Formats Change

Capacity is meaningless without naming the block size, the pieces per mould, and the cycle time that produced the number.

I watched a plant owner in Java argue with his line manager over a shortfall that never should have surprised either of them. The quote said the machine could push 9600 hollow blocks in an eight-hour shift. Nobody asked which hollow block. When they switched from 200 mm to 150 mm cavity walls, the mould changed, the cycle shifted, and the daily count moved with it. The QT5-15 block machine specifications only hold their ground when tied to a specific format — 5 pieces per mould for a 400×200×200 mm hollow block at 15-20 seconds, or 6 pieces per mould for a 400×150×200 mm unit at the same interval. Swap the mould and the arithmetic follows. [NEED_CITE: block format impact on daily output planning]

Format-by-Format Output for the Concrete Brick Machine Mould Capacity

Every number in the output table above traces back to a defined block dimension, a fixed pallet area of 1100×550 mm, and a stated pieces-per-mould count. A technical buyer sizing a line for hollow blocks sold in a specific local market can pull the exact row that matches their product. No averaging across formats, no catalogue headline that dissolves when the mould changes.

Where Cycle Time Diverges Between Block Types

Hollow blocks and solid bricks share a 15-20 second cycle window on this press. Pavers and interlocking bricks move to 20-25 seconds because the higher density requirement demands longer vibration exposure and more hydraulic dwell. The difference is small per cycle but compounds across a shift, and it changes the pallet return rate and the curing rack throughput downstream.

Vibration Force, Hydraulic Pressure, and the 1100×550 mm Pallet

The 80 kN platform vibration sits beneath the mould table, isolated from the independent hydraulic station so that high-frequency oscillation does not travel through valve blocks and hose fittings. That separation matters for component life in a plant running three shifts. The pallet dimension of 1100×550 mm is fixed for this model — before confirming an order, the buyer must check that their existing curing racks, forklift tines, and stacking area accept that exact footprint. A mismatch here means pallets sit on the floor or racks go half-empty.

The Cost of Skipping the Aggregate Question Before Purchase

Standard sand behaves nothing like volcanic ash, crushed coral, or the washed river gravel available in parts of Sumatra and the Visayas. When a machine arrives configured for a mix the buyer cannot source, the plant either imports material at unsustainable cost or retunes vibration force and feed timing on-site — which takes the line offline and burns through the commissioning window. I have seen two full weeks lost because the press was set for a textbook aggregate that did not exist within 300 kilometres of the job site.

Why Procurement Decisions Land Better Here

Block machinery is the single production focus, which means the press, mould, pallet, and handling stations arrive as one matched set rather than a collection of separate purchases. Configuration starts from the buyer’s actual mix design and target format, not a catalogue default row. Mould design covers the formats the local market actually buys, with custom drawings available. Automation level is selectable, so a semi-automatic start can grow into full stacking and cubing later.

Before You Send the Inquiry

Share the block format your market actually sells — dimensions, target compressive strength, and whether fly ash or slag is part of the local supply. State the daily output you need per format, not an average across types. Confirm your available voltage, frequency, and the language your operators read on a screen. If you already have curing racks and a forklift, send the pallet footprint they accept.

Frequently Asked Questions

Q: How is the QT5-15 capacity calculated per block format?
A: Each output row names a specific block size, pieces per mould, and cycle time. The 7200-9600 pieces per 8-hour shift applies to a 400×200×200 mm hollow block at 5 pieces per mould and a 15-20 second cycle. Switch to pavers and the cycle extends, changing the total accordingly.

Q: Which mould formats come standard and how long does a change take?
A: The standard range covers hollow block, solid brick, rectangular paver, and zigzag interlocking brick. Mould change time depends on the quick-release system specified at order — confirm the procedure and timing in the mould drawing package before production starts.

Q: How is the machine tuned to local aggregate rather than a default mix?
A: Configuration begins with the buyer’s material sample and target block strength. Vibration frequency, hydraulic pressure, and feed timing are set against that mix. The PLC stores parameters per mould, so switching formats restores the correct settings automatically.

Q: What pallet size does the QT5-15 use and why does it matter?
A: The pallet measures 1100×550 mm. This dimension must match the buyer’s curing racks, stacking area, and forklift tine spacing. A mismatch causes pallets to pile on the floor or racks to run below capacity, creating a bottleneck downstream of the press.

Q: How are voltage and PLC language confirmed before production?
A: Both are signed off in writing after inquiry and before the machine enters the build stage. The buyer states local voltage, frequency, and preferred display language. These are recorded in the specification sheet and verified during the factory test.
