What "15–20 Second Cycle" Actually Means for Your Output
Cycle time shifts with every block format, and the daily output figure on a quotation only holds if the assumed format matches what your market actually buys.
I have watched buyers sign contracts on a headline cycle number, then discover that the hollow block their region demands pulls the cycle to the upper end of the range while the paver they quoted against sat comfortably at the lower end. The gap between those two realities can swallow an entire shift of expected production. When you evaluate any automatic block making machine specifications sheet, the question is never "how fast does it cycle" but "how fast does it cycle on the exact block I sell, with the exact aggregate I can source."

Mould Format Dictates the Real Production Day
The QT6-15 ships with mould options for hollow blocks, solid blocks, pavers and curbstones, and each format sits at a different point within the 15–20 second moulding cycle range. A buyer sizing a machine to a specific product and market needs a written capacity table listing every format they intend to run, its individual cycle time, and the resulting daily output — not a single aggregate number that blurs the differences. This is where honest automatic block making machine specifications separate useful planning tools from marketing brochures.
Pallet Size Must Match What You Already Have
The 1020 × 900 mm pallet is a fixed dimension on this press, which means your curing rack spacing, forklift fork width and stacking workflow must accommodate it — not the other way around. Confirming pallet compatibility before the machine ships prevents the costly surprise of arriving pallets that your existing racking cannot accept.

Vibration and Pressure Tuned to Your Aggregate
The 55 kN exciting force works in combination with the high-pressure hydraulic station to compact the mix into the mould. That combination must be matched to your specific aggregate gradation and cement content to deliver consistent block density and strength across every batch. A mix that performs well under one vibration-pressure setting may produce weak, crumbly output under another, which is why factory testing with the buyer’s actual material sample matters before the machine leaves the workshop.
Reading the Numbers That Matter
The 37.2 kW rated power covers the press, hydraulic station and vibration motors running together, so the electrical supply at the destination must support continuous draw at that level plus starting surge. The JS750 mixer paired with this line sets the batch volume per mix cycle, and its throughput must keep pace with the press demand to avoid the press standing idle between batches. The 8300 × 1860 × 3000 mm overall footprint determines the minimum building envelope, and the 8 T total weight governs foundation design and floor loading — both must be confirmed against the buyer’s site before installation planning begins.
The Cost of Skipping the Format Conversation
When the mould format, pallet size and mix design are not confirmed as a matched set before the order is placed, the consequences surface at commissioning. Blocks crack during curing because the vibration force was set for a different aggregate. Mould changes consume most of a shift because the quick-change system was not specified for the number of formats the buyer actually rotates through. Pallets pile up on the floor because the automatic stacker was left out of the quotation to save cost, forcing manual handling that bottlenecks the entire line.

Why Source This Configuration Here
The machine, mould, pallet and handling equipment are specified together as one matched line, so the pallet feeder, block conveyor and sweeper arrive aligned to the press cycle rather than sourced separately and reconciled on site. Configuration is set against the buyer’s actual mix design and local aggregate sample, not a default that assumes ideal sand and cement. Mould design covers the formats the buyer’s market sells, with custom drawings reviewed before tooling begins. Automation level is selectable, so a plant can start with the standard automatic package and add stacking or cubing functions later. Factory testing uses the buyer’s confirmed mix proportion so the test record reflects real production conditions, not a generic benchmark.

What We Need to Size Your Line Correctly
Share the specific block formats your market demands, the local aggregate and cement you plan to use, and your target daily output per format so the capacity calculation reflects reality. Confirm the voltage, frequency and PLC language required at your site, along with the pallet handling and curing infrastructure you already operate, so the line integrates without gaps.
Frequently Asked Questions
Q: How is capacity calculated per block format on the QT6-15?
A: Each mould format — hollow block, solid block, paver, curbstone — has a distinct cycle time within the 15–20 second range. We provide a written table listing every format, its individual cycle, and the resulting daily output so the capacity figure matches what you actually plan to produce rather than a single generic headline number.
Q: How do I confirm the 1020 × 900 mm pallet fits my curing setup?
A: Before the order is placed, share your curing rack dimensions, spacing and forklift fork width. We cross-check the pallet against your existing infrastructure so the pallets arriving on site slot directly into your curing workflow without requiring rack modification or new handling equipment.
Q: What is involved in a mould change on this machine?
A: The QT6-15 requires a physical mould swap to switch between block formats. We confirm the change procedure, tooling requirements and expected downtime during the configuration stage so you can plan format rotations around your production schedule rather than discovering the time cost after delivery.
Q: How is vibration force tuned to my local aggregate?
A: We request a sample of your local sand, crushed stone and cement to run a mix trial. The 55 kN vibration force and hydraulic pressure are then adjusted together to achieve consistent block density and strength for your specific material, and the settings are recorded in the factory test documentation.
Q: What electrical details must be confirmed before production begins?
A: Voltage, frequency and PLC display language are confirmed in writing before the machine enters production. This prevents commissioning delays caused by mismatched electrical standards or an operator interface the local team cannot read when the machine arrives at the plant.
