Why "Pieces per Hour" Means Nothing Without the Format Attached

Every output figure on this page names the exact block format and mould cavity count it assumes.

When a quotation lists a single capacity number, it almost always refers to the smallest, fastest-cycling format the machine can run. Buyers then plan their revenue around solid brick throughput and are surprised when their actual product — a 200 mm hollow block — delivers a fraction of that volume. The QT4-15A fully automatic block making machine for sale here states three separate capacities so you can match the number to the block your market actually buys [NEED_CITE: common discrepancies between quoted and actual block plant output].

A 400×200×200 mm hollow block mould holds 4 cavities and cycles at 15–25 seconds, yielding 408 pieces per hour and roughly 3264 pieces in an eight-hour shift. Switch to a 240×115×53 mm solid brick mould with 18 cavities and the same press delivers 2100 pieces per hour. The machine does not change; the format does. Any supplier who quotes one number for all formats is leaving out the only detail that matters for your business plan.

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

The SHIYUE range spans semi-automatic machines for low-investment starts, mid-tier automatic lines like this fully automatic block making machine for sale, and high-capacity plants for large-volume producers. The QT4-15A occupies the middle position: it delivers full PLC-controlled automation with pallet feeding, conveying and sweeping, yet its 3-tonne weight and 7.1-metre line length keep the plant footprint within reach of a first commercial setup. Buyers moving up from a mobile egg-laying machine or a semi-automatic press will find the automation step removes manual pallet handling without requiring the infrastructure of a high-capacity line.

Matching Machine Tier to Your Actual Production Volume

Choosing a tier is not about maximum possible output; it is about the daily volume your market absorbs and the capital you are prepared to deploy. A contractor producing hollow blocks for a single housing project may never need the throughput of a high-capacity line, and the extra automation stages would sit idle. The QT4-15A is specified for plants targeting several thousand hollow blocks or over ten thousand solid bricks per shift, with the option to add formats through mould changes as market demand shifts [NEED_CITE: block plant sizing against local construction demand]. Starting at this tier also leaves room to add automatic stacking and cubing later if volume grows.

Reading the Specification Sheet Against Real Production Conditions

Vibration frequency at 4600 r/min and exciting force between 40 and 50 kN determine how densely the mix is compacted inside the mould. Higher force and frequency produce stronger blocks, but only when the mix design and aggregate grading suit that energy level; a lean mix with oversized aggregate may fracture under maximum vibration rather than consolidate. The high-pressure hydraulic station supplies the pressing force that works in tandem with vibration, and its rating must be confirmed against your target block strength. Pallet size at 850×550×25 mm governs both the mould footprint and the curing area layout — if your existing forklifts and curing racks are sized for a different pallet, the mismatch will surface on day one. The 18.45 kW total power draw dictates the supply circuit you need to prepare before the machine arrives.

What Happens When Voltage and Language Are Left to Chance

Arriving at a job site to commission a new block line and discovering the PLC display is in a language your operators cannot read is a preventable delay, yet it happens regularly. The same applies to voltage and frequency: a machine wound for 380 V / 50 Hz will not start on a 440 V / 60 Hz supply without transformer or motor changes that add weeks to commissioning [NEED_CITE: voltage and frequency standards by export market]. Confirming these details in writing before production begins costs nothing; resolving them after the machine is bolted to the floor costs time and money.

Why Buyers Source This Fully Automatic Block Making Machine for Sale Here

Block machinery is the sole focus of SHIYUE’s engineering and production, which means the press, mould, pallet and handling equipment are specified as one matched system. Configuration is set against your actual mix design, local aggregate and target block format rather than a catalogue default. Mould design and supply cover the formats your market sells, with custom drawings available when standard moulds do not match. The automation level is selectable — you can start with the pallet feeder, conveyor and sweeper included here and add stacking or cubing stages later. Installation support includes on-site commissioning and operator training so the line runs correctly from the first shift.

Documentation & Verification

• Line layout and capacity calculation stating the block format assumed for each output figure

• Dedicated power circuit matching confirmed voltage and frequency for the 18.45 kW total load
• Line components arrive dismantled for container loading and are reassembled on-site during commissioning
• First-run parameter setting covers molding cycle, vibration duration and hydraulic pressure for your mix
• Operator training addresses PLC operation, mould change procedure and daily maintenance routines
• Wear parts list and spare tools ship with the machine to cover initial replacement cycles

Before You Request a Quote

To configure the QT4-15A for your plant, share the block formats your market demands, the daily volume you plan to produce and the raw materials available locally including aggregate grading. Include your site voltage, frequency and preferred PLC display language so these are locked in before manufacturing. If you have existing curing racks, forklifts or pallets on site, provide their dimensions so the pallet and handling specification aligns with what is already in place.

Frequently Asked Questions

Q: How is the output capacity calculated and which block format does each figure assume?
A: Every capacity figure on this page is tied to a specific block format and mould cavity count. For example, 408 pieces per hour assumes a 400×200×200 mm hollow block with 4 cavities per mould at a 15–25 second cycle. Solid brick capacity is stated separately at 2100 pieces per hour based on 18 cavities. No single blended number is used.

Q: Where does the QT4-15A sit in the full machine range?
A: This model sits in the mid-tier of the SHIYUE automatic range. It offers full PLC control with pallet feeding, conveying and sweeping, positioned above semi-automatic entry-level machines and below high-capacity automatic lines. It suits plants scaling up from manual operation or starting a first commercial block production setup.

Q: What voltage, frequency and PLC language options are available?
A: These are confirmed in writing before production begins, matched to the destination market’s electrical standards and the buyer’s preferred operating language. Stating requirements at inquiry stage prevents commissioning delays caused by mismatched motors or unreadable control displays.

Q: Which moulds are included and can I add formats later?
A: The machine supports hollow block, solid brick, paver and curbstone production through mould changes. The quotation specifies which moulds ship with the line. Additional moulds and custom format designs can be supplied separately as market demand changes.

Q: What supporting equipment is included and what must I prepare on-site?
A: The line ships with the hydraulic station, PLC control system, pallet feeder, brick conveyor, block sweeper and a manual hydraulic trolley. Buyers prepare the foundation, power circuit and curing area to match confirmed pallet dimensions before the machine arrives for installation.
