Moulds for Concrete Hollow Blocks and Hollow Bricks
Factory-direct plastic and ABS moulds for concrete hollow blocks and hollow bricks — 54 designs including three-in-one multi-cavity and double-sided S30 series.
Hollow block moulds — also called concrete block making moulds or hollow bricks moulds — are used to cast the cored masonry units that form walls, partitions, boundary walls and ventilated screens. Because the core geometry decides both block weight and mortar key, hole shape and wall thickness are the two parameters buyers check first.
Zhihua supplies 54 hollow block mould designs: ABS three-in-one and two-in-one multi-cavity moulds that cast three blocks per pour, a 22-design double-sided S30 series in 30×30×10cm, numbered 20×20cm patterns, plus square-hole, round-hole, angled-hole, arched-hole and ventilation block moulds. Standard catalogue designs and OEM patterns are both available.
54 qualified product examples across 4 categories. More sizes and patterns can be quoted from drawings or sample photos.

Hollow block mould selection is driven by finished block size, hole geometry and how many blocks you need per pour. Multi-cavity ABS moulds cut labour per block but need a flatter casting bed.
For hollow block moulds, the key parameters are finished block dimensions, hole shape and wall thickness between cores. Tell us your target blocks-per-day and we can advise on cavity count.
| Application | Suitable mould type | Key parameters |
|---|---|---|
| Volume block production | ABS three-in-one multi-cavity moulds | Block size, cavity count, casting bed flatness |
| Decorative / double-faced walls | Double-sided S30 series 30×30×10cm | Pattern design, thickness, both-face finish |
| Ventilated screens & infill | Ventilation and angled-hole block moulds | Hole geometry, open area, block height |
Hollow block orders are usually driven by finished block size and target output. Send the block dimensions plus your blocks-per-day target and we will recommend single or multi-cavity moulds.
Send your drawing or a photo of the target result. We can review catalogue options or OEM mould feasibility.

If you need a cell pattern or block size that is not on this page, send a drawing or a photo with dimensions and we will check it against our tooling.
A hollow block mould casts concrete masonry units with internal cores. The cores reduce block weight, save concrete, improve insulation and give mortar a mechanical key. Blocks are used for boundary walls, partitions and ventilated screens.
Single-cavity moulds cast one block per pour. Our ABS three-in-one moulds cast three blocks per pour and two-in-one moulds cast two, which significantly reduces labour cost per block.
A hollow block mould has core formers that create internal voids, so the finished unit is lighter and uses less concrete. A solid block mould produces a fully filled unit with higher compressive strength but more weight and material cost.
Yes. Send the block drawing or a sample photo with finished dimensions, hole layout and wall thickness. We review draft angles and demoulding direction, then quote OEM mould production.
