Cement Paving Block Making Machine for Hollow Brick – Manufacturer

Matched System Approach — the QT4-18 block making machine manufacturer configures the press, mould, pallet and handling as one verified set rather than sourcing each from separate suppliers.

What "1200 Pieces per Hour" Leaves Out

Capacity figures mean nothing unless the block format and cycle time are stated alongside them.

Most block making machine manufacturer catalogues quote a single hourly number without telling you which mould was in the press when that number was measured. I once saw a buyer receive a machine rated for a certain output, only to find that figure assumed a solid brick mould while their market needed 400×200×200 mm hollow blocks — the actual throughput dropped to a fraction of what was expected. The QT4-18 data sheet shows different outputs depending on whether you run hollow blocks, solid bricks or pavers, and each figure ties back to a specific cycle window of 15–25 seconds.

Where the QT4-18 Sits in the Full Machine Range

The SHIYUE range spans mobile egg-laying machines at the entry end, semi-automatic presses like this block making machine manufacturer model in the middle, and fully automatic lines with batching, stacking and cubing at the top. The QT4-18 occupies the semi-automatic tier, meaning the press itself runs under hydraulic and vibration control while pallet feeding and product handling still involve some operator input — though an automatic stacker is included to reduce manual lifting at the discharge end.

Reading the Range Before You Commit

Buyers who are setting up a first plant often start at this tier because it delivers hydraulic pressure and vibration forming without the capital outlay of a full automatic line. The key question is whether your daily volume target and local labour cost justify stepping straight to a higher tier, or whether starting semi-automatic and adding automation modules later makes more financial sense. [NEED_CITE: automation upgrade paths in concrete block production] The SHIYUE range is structured so that pallet sizes and control logic carry forward, meaning an upgrade does not require scrapping the existing press.

How Vibration Force and Hydraulic Pressure Shape Block Density

The QT4-18 delivers 40–50 kN of vibration force combined with hydraulic compression from above. In practice, the vibration settles the aggregate into the mould cavity while the hydraulic head applies downward pressure to compact the mix — the balance between these two forces determines whether the finished block has uniform density or weak spots at the corners. A mix with high fly ash content responds differently than one based on crushed stone, which is why the vibration and pressure settings need adjustment once your specific raw material arrives on site. The 850 × 550 mm pallet size defines the mould footprint; every mould you order must match this dimension or the feeding system will not index correctly. Mould change on a semi-automatic tier typically involves manual clamping, so the time it takes to swap formats depends on how many bolts and alignment pins the mould design requires.

The Cost of Ignoring Pallet and Curing Area Alignment

When the pallet size is chosen without checking the buyer’s existing curing racks and forklift tine width, the result is pallets that cannot be stacked in the curing area or moved by the equipment already on site. I have seen plants where 300 pallets sat unused because the curing yard was designed for a different dimension. The QT4-18 recommends 300–500 pallets in either fiberglass or wood — fiberglass lasts longer under repeated vibration cycles, but wood may be the only option if your local supplier cannot source the fiberglass grade. [NEED_CITE: pallet material durability under vibration forming] Choosing wrong here means either replacing pallets within months or reconfiguring the entire curing layout.

Why Buyers Source This Tier from SHIYUE

The machine, mould, pallet and handling equipment are specified as one matched system, so the pallet size, vibration rating and mould cavity count are verified together before the order goes to production. Configuration is set against the buyer’s actual mix design and local aggregate rather than a catalogue default — if your sand has high clay content, the vibration parameters are adjusted accordingly. Mould design covers the formats your market actually sells, including custom drawings if your region demands a non-standard paver profile. The semi-automatic level lets you start with controlled investment and add automation modules as volume grows, and the pallet and control architecture carry forward into higher tiers.

• Wear parts list covers mould liners, vibration springs and hydraulic seals

What to Prepare Before Requesting a Quotation

Share the block formats your market sells, the daily output you need per format, and the raw materials available locally — especially aggregate type and any fly ash or dust you plan to use. Confirm your site voltage, frequency and preferred PLC display language so the control panel is built correctly before the QT4-18 leaves the factory.

Frequently Asked Questions

Q: How is QT4-18 capacity calculated per block format?
A: Each output figure is tied to a specific mould and cycle time within the 15–25 second range. A hollow block mould with four cavities produces fewer pieces per cycle than a solid brick mould with a higher cavity count, so the hourly number changes with the format. Always ask for capacity stated per block type.

Q: When should a buyer step up from QT4-18 to a fully automatic model?
A: If your daily volume target requires continuous multi-shift operation and your local labour cost makes manual pallet handling expensive, a fully automatic line with batching and cubing becomes justified. The semi-automatic tier suits single-shift plants or buyers testing a new market.

Q: What voltage and PLC language options are confirmed before shipment?
A: Voltage, frequency and phase are confirmed during the order stage to match the buyer’s site supply. PLC display language is also locked in at this point so the operator interface is readable from the first day of commissioning, avoiding costly reprogramming after arrival.

Q: What pallet size does the QT4-18 require?
A: The machine uses 850 × 550 × 25 mm pallets in fiberglass or wood. Before ordering, check that this dimension fits your existing curing racks and that your forklift tine width can handle the loaded pallet. Mismatched pallets delay production from day one.

Q: What is the upgrade path from this semi-automatic tier?
A: The SHIYUE range shares pallet dimensions and control logic across tiers, so adding automatic pallet feeding, stacking or cubing modules is possible without replacing the press. Discuss your growth plan early so the base machine is configured to accept future automation additions.
