QT4-15A Automatic Hydraulic Block Making Machine – Full Range

Matched System Design — The QT4-15A is specified as one integrated line from the hydraulic press through to the pallet feeder, brick conveyor, and block sweeper, so cycle times match across every station rather than leaving the press idle while upstream or downstream equipment catches up.

What "3264 Blocks per Shift" Actually Assumes

The QT4-15A output of 3,264 hollow blocks per eight-hour shift is rated specifically on a 400×200×200 mm format — switch the mould and that number changes.

Most quotations lead with a single headline capacity figure. That number is usually tied to one block format, often the smallest or fastest to press. When a buyer’s real production target is a different format — say a 400×150×200 mm hollow block or a solid brick — the cycle time and pieces-per-mould shift, and so does the daily total. I have watched buyers sign contracts expecting a quoted output, only to discover on commissioning day that their actual format runs noticeably slower. As an automatic hydraulic block making machine manufacturer, SHIYUE states output per format in the capacity calculation so the buyer can verify daily volume against their own market demand before the order is placed [NEED_CITE: block format assumptions in capacity quotations].

Placing the QT4-15A on the Full SHIYUE Range

The QT4-15A occupies the mid-tier position within the complete SHIYUE block machine lineup. Below it sit semi-automatic models suited to smaller workshops where investment budgets are tighter and pallet handling can be managed manually. Above it, higher-capacity automatic lines add fully automated stacking and cubing for plants targeting large daily volumes. This machine bridges the gap: it delivers PLC-controlled hydraulic pressing and vibration with a matched pallet feeder, brick conveyor, and block sweeper already included, giving a buyer a genuinely automatic line without stepping into the footprint and capital outlay of the largest tier.

How the Automatic Tier Differs from Semi-Auto and Mobile

Semi-automatic machines rely on operators to move pallets in and out, which keeps the purchase price lower but ties daily output to crew stamina and shift discipline. Mobile egg-laying machines produce directly on the ground, eliminating pallets altogether but limiting the formats and finishes available. The QT4-15A, as an automatic hydraulic block making machine, removes the pallet handling variable from the operator’s workload. The pallet feeder indexes a new board into position on each cycle, the conveyor carries finished blocks away, and the sweeper cleans pallets before they return — the operator monitors the PLC rather than moving steel and concrete by hand.

Reading the Specs That Shape Daily Output

The vibration force of 40–50 kN at 4,600 r/min works together with the hydraulic station’s pressing pressure to compact the mix into the mould. Higher vibration frequency reduces air voids, while hydraulic pressure locks the aggregate matrix into shape before the block leaves the press [NEED_CITE: hydraulic pressure and vibration force in block compaction]. The moulding cycle of 15–25 seconds reflects the range across formats: a thin solid brick cycles faster than a tall hollow block that needs more fill time. The 850 × 550 × 25 mm pallet size determines how many blocks fit per press stroke and must align with the curing racks and forklifts the buyer already has on site — ordering pallets that do not match existing racking is a surprisingly common oversight.

When the Wrong Configuration Reaches the Site

A machine configured for a standard river sand mix will underperform if the buyer’s local aggregate is volcanic ash or crushed coral. The vibration force and hydraulic pressure settings that produce strong blocks with one material may leave blocks crumbling with another. Similarly, arriving at a site with an unconfirmed voltage or a PLC display in a language the operators cannot read delays commissioning by days or weeks [NEED_CITE: voltage and frequency mismatches at commissioning]. These are not machine defects — they are specification gaps that surface only once the equipment is bolted to the floor.

Why Buyers Source the QT4-15A Through SHIYUE

The QT4-15A is supplied as one matched system: press, hydraulic station, PLC, pallet feeder, conveyor, and sweeper are specified together so cycle times align across every station. The capacity calculation names the exact block format behind each output figure, so buyers compare tiers on real numbers. Mould options cover the formats the buyer’s market actually purchases, and custom drawings are available when a standard mould does not fit. Voltage, frequency, and PLC language are confirmed before production starts, not discovered at the container. The upgrade path is built in — a buyer can start with the QT4-15A’s automatic configuration and later add stacking or cubing modules as demand grows.

What We Need Before Quoting Your Line

To match the QT4-15A to your actual production target, share the block formats your market demands, the daily volume you need per format, and the raw materials available locally — especially the aggregate type and moisture range. Confirm your site’s voltage, frequency, and preferred PLC display language so the electrical package is built correctly before the machine ships. If you already have pallets, curing racks, or a forklift on site, send the dimensions so the pallet feeder and conveyor are set to match.

Frequently Asked Questions

Q: How is QT4-15A output verified per block format?
A: Each output figure in the capacity table is tied to a specific block dimension — for example, 408 pieces per hour assumes a 400×200×200 mm hollow block. When you share your target format, the capacity calculation is recalculated using that mould’s cycle time and cavity count, so the daily volume you plan around matches what the machine actually delivers on your product.

Q: Where does the QT4-15A sit compared to other SHIYUE tiers?
A: It is the entry point of the fully automatic tier, sitting above semi-automatic models that require manual pallet handling and below high-capacity lines with integrated stacking and cubing. Buyers choose it when they want PLC-controlled automation without the plant footprint and investment of the largest tier.

Q: What electrical details are confirmed before production?
A: Voltage, frequency, and PLC display language are all confirmed with the buyer before the electrical cabinet is wired. This prevents commissioning delays caused by mismatched supply or operators unable to read the control interface — issues that are simple to fix on paper but difficult once the machine is on a ship.

Q: What supporting equipment does the QT4-15A line require?
A: Beyond the included press, pallet feeder, conveyor, and sweeper, the buyer needs a mixer such as the JQ350, pallets sized 850 × 550 × 25 mm, a curing area with compatible racks, and a forklift or trolley for moving cured blocks. The line layout document shows spacing for each station so you can plan the floor area.

Q: Can the QT4-15A be upgraded later for higher automation?
A: Yes. The machine’s automation level is modular, so a buyer can start with the standard pallet feeder and conveyor configuration and later add automatic stacking or cubing equipment as production volume grows, without replacing the press or hydraulic station.
