QT4-15A Maquina Automatica Para Fabricar Ladrillos | Full Range

Matched System Design — the QT4-15A block machine, moulds, pallets and handling equipment are specified together as one coordinated line rather than sourced separately.

What "Pieces per Hour" Actually Means on the QT4-15A

Every output figure here is tied to a specific block format, mould cavity count, and an eight-hour shift assumption — no single "up to X per hour" headline number.

Buyers comparing automatic block making machine manufacturer options often see capacity stated as one peak figure without disclosing which block size produced it. A hollow block and a solid brick share the same pallet cycle, yet their per-mould counts differ dramatically. I have watched contractors order a machine based on a brochure number, only to discover their actual product format yields far fewer units per shift than expected [NEED_CITE: block machine capacity calculation methods by format].

Where the QT4-15A Fits in the Full Machine Range

The SHIYUE line spans semi-automatic machines for smaller workshops through high-capacity fully automatic plants. The QT4-15A sits in the mid-tier of this automatic block making machine manufacturer range, delivering PLC-controlled cycling with integrated pallet feeding and brick conveying. It targets buyers who need consistent automated output without the floor space and capital outlay of a high-capacity line.

Semi-Automatic Versus This Tier

Semi-automatic machines in the range require manual pallet handling and stacking, keeping investment lower but tying labour to every cycle. The QT4-15A removes the operator from pallet feeding and block conveying, reducing the labour count on the press itself. Buyers planning to scale can start at this tier and move upward as demand grows [NEED_CITE: automation level comparison in block production plants].

Reading the Vibration and Pressure Numbers Together

Vibration force of 40–50 kN at 4600 r/min works alongside the hydraulic station to compact the mix inside the mould cavity. Neither number alone determines block strength. The vibration must fluidise the mix while hydraulic pressure locks the particles into position. If the local aggregate carries high clay or silt content, the vibration frequency may need adjustment — a reason to share material samples before finalising the configuration. Pallet size at 850×550×25 mm should be checked against the buyer’s existing curing racks and forklift fork dimensions to avoid mismatches after the machine arrives.

When the Wrong Configuration Costs More Than the Machine

A buyer who skips voltage and frequency confirmation before production may receive a machine that cannot connect to the local grid, stalling commissioning for weeks. Pallets specified without regard to the curing yard layout force manual re-stacking that erases the automation advantage. Mould formats ordered without verifying local market dimensions mean the machine produces blocks the market does not buy [NEED_CITE: common commissioning delays in exported block machinery].

Why Source This Range Here

Block machinery is the single focus, so the QT4-15A is not a generic press resold under a different label — the mould, pallet, and handling equipment are matched to the same production parameters. Configuration is set against the buyer’s actual mix design and target block format, not a default catalogue entry. Mould design covers the formats the buyer’s market requires, including custom drawings where standard sizes do not apply. Automation level is selectable within the range, so a buyer can begin semi-automatic and upgrade later.

Frequently Asked Questions

Q: How is output capacity calculated per block format on the QT4-15A?
A: Each output figure is based on a specific mould cavity count and block dimension. For example, the 400×200×200 mm hollow block mould holds 4 cavities, yielding 408 pieces per hour at the stated cycle range. Solid brick output is higher because 18 cavities fit the same pallet. Daily figures assume an eight-hour production shift.

Q: Where does the QT4-15A sit compared to semi-automatic and higher-tier machines?
A: It occupies the mid-tier of the automatic range. Semi-automatic models require manual pallet handling at lower investment. Higher-tier automatic lines add stacking and cubing systems with larger footprints. The QT4-15A integrates pallet feeding and brick conveying without the space demand of a full high-capacity plant.

Q: How are voltage, frequency, and PLC language confirmed before shipment?
A: The buyer provides local grid specifications and preferred control language during the inquiry stage. A written confirmation document is issued before production begins. This step prevents commissioning delays caused by mismatched electrical supply or unreadable PLC displays on arrival.

Q: How is pallet size matched to existing curing and handling equipment?
A: The standard pallet size is 850×550×25 mm. Buyers share their curing rack dimensions and forklift fork specifications so compatibility is verified before order. Mismatched pallets force manual re-handling that undermines the automation investment.
