Starting a brick manufacturing business doesn’t always mean investing in a million-dollar production line. If you’re supplying bricks for local construction projects, a hydraulic brick making machine from YG gives you solid output without the overhead of a fully automated plant. YG builds semi-auto machines that produce up to 24,000 standard bricks per shift with just 2-3 operators — and the price point makes sense for small to mid-scale operations. Here’s a full look at what YG offers, how these machines work, and where they’re already in use around the world.

Hydraulic Brick Making Machine Specifications & Models
Before we dive into features, let’s look at the numbers. YG currently offers 6 semi auto brick making machine models, divided into two series (A and B) with optional hopper upgrades.
| Model Features | YG4-35A | YG4-35A (Hopper) | YG4-35B | YG4-35B (Hopper) | YG4-40A | YG4-40A (Hopper) |
| Molding Cycle | 35s | 35s | 35s | 35s | 35s | 35s |
| Power (kw) | 4.8 | 4.8 | 6.3 | 6.3 | 7.5 | 7.5 |
| Standard Bricks/Shift | 15,000 | 20,000 | 15,000 | 20,000 | 20,000 | 24,000 |
| Hollow Blocks/Shift | 2,400 | 3,200 | 2,400 | 3,200 | 3,200 | 3,600 |
| Machine Weight | 750kg | 780kg | 800kg | 830kg | 1100kg | 1150kg |
| Operators Needed | 2-3 | 2-3 | 2-3 | 2-3 | 2-3 | 2-3 |
How to choose: The A series suits startups and smaller yards — lower power, lighter weight, easier to move. The B series steps up for higher-volume operations. Adding a hopper boosts per-shift output by roughly 30% because it cuts manual feeding time. The YG4-40A (Hopper) is the top performer at 24,000 bricks per shift.

How Does a Hydraulic Brick Machine Work?
If you’ve never operated a hydraulic brick machine before, the process is simpler than you might think. Here’s what happens from raw material to finished brick:
Step 1 — Material Preparation. Mix cement, sand, fly ash, stone dust, and water in a concrete mixer. The ratio depends on your target brick strength, but a common mix is 1 part cement : 3 parts sand : 3 parts fly ash.
Step 2 — Feeding. Load the mixed material into the machine’s feed hopper (or directly into the mold box for models without a hopper). The hopper models save time because workers don’t need to shovel material into each mold cycle.
Step 3 — Hydraulic Pressing. The core of the process. A hydraulic cylinder applies high pressure to compress the material inside the mold. This pressure ensures the bricks come out dense, uniform, and with sharp edges — something manual molding simply can’t match.
Step 4 — Vibration & Compaction. Simultaneously, vibration motors shake the mold to eliminate air pockets and further compact the material. The combination of hydraulic pressure + vibration is what gives these bricks their consistent quality.
Step 5 — Ejection & Stacking. The mold opens, and the finished bricks eject onto a pallet or conveyor. Workers stack them for curing. The entire cycle takes just 35 seconds per batch.
Step 6 — Curing. Fresh bricks cure naturally in the sun for 7-14 days (or in a steam chamber for faster turnaround). No kiln firing needed — that’s a major cost saving compared to clay brick production.

YG Hydraulic Brick Machine Features & Advantages
1. 35s Molding Cycle — Fast Enough for Real Demand
Every YG model runs a 35-second cycle, which translates to 15,000-24,000 standard bricks in an 8-hour shift. For context, a team of 5 manual molders produces roughly 2,000-3,000 bricks in the same time. One machine replaces a small crew.
2. 4.8kw Starting Power — Runs on Small Generators
The entry-level YG4-35A draws just 4.8kw. That means you can run it on a standard diesel generator at remote sites where grid power isn’t available. No need to invest in heavy electrical infrastructure before you start producing.
3. Only 2-3 Operators Needed
Every model in the lineup runs with 2-3 people — one feeds material, one operates the controls, one handles stacking. Compare that to manual production where 5-6 workers produce less. The labor savings pay for the machine fast.
4. Hopper Upgrade Boosts Output 30%
Choose the hopper version and per-shift output jumps significantly — from 15,000 to 20,000 on the A series, and from 20,000 to 24,000 on the B series. The hopper holds a batch of material so workers don’t stop to refill between every cycle.
5. Compact and Relocatable
At 750-1,150kg, these machines fit on a flatbed truck. Move them between sites, relocate as your project evolves, or transport them to a new market. No concrete foundation or permanent installation required.
6. Versatile Mold Options
YG offers interchangeable molds for standard bricks, hollow blocks, and paving stones. Switching molds takes about 30 minutes. One machine, multiple products — that flexibility helps you serve different customer needs without buying separate equipment.

Hydraulic Brick Making Machine in Action — International Cases
Case 1: Nairobi, Kenya — From Manual Molding to YG4-35B (Hopper)
How the client found YG: James, a building material supplier in Nairobi, came across YG Machinery through an Alibaba product listing in late 2024. He was looking for an upgrade from his team of 8 manual brick molders, who produced inconsistent quality and couldn’t keep up with growing demand from local contractors.
What James needed: Higher daily output, consistent brick quality, and a machine that could run on his existing 15kVA diesel generator without upgrading.
How YG helped: After a WhatsApp video call to assess his site conditions, YG’s sales engineer recommended the YG4-35B (Hopper) — 6.3kw power draw (well within his generator capacity), 20,000 bricks per shift, and the hopper to reduce manual feeding labor.
The results:
- Daily output increased from 2,500 bricks (manual) to 18,000+ bricks per shift
- Brick breakage rate dropped from ~15% to under 3%
- James reduced his molding crew from 8 workers to 3, redirecting the others to stacking and delivery
- The machine paid for itself in roughly 4 months based on increased sales volume
James’s feedback:“The quality difference is night and day. My clients now ask specifically for my machine-made bricks because they know the dimensions are exact. The hopper was a good call — we stop less often and the guys are less tired.”
Case 2: Cebu, Philippines — Scaling a Hollow Block Business with YG4-40A (Hopper)
How the client found YG: Maria runs a hollow block supply business in Cebu, Philippines. She found YG through a Google search for “semi auto brick making machine” in early 2025. Her existing machine — a small manual press — was breaking down constantly and couldn’t produce enough to fulfill a new contract with a housing developer.
What Maria needed: A reliable machine that could produce hollow blocks at scale (her contract required 3,000+ blocks per day), with simple operation her existing staff could learn quickly.
How YG helped: YG’s team reviewed her requirements — mainly hollow block production, moderate volume, and limited technical staff — and recommended the YG4-40A (Hopper) . At 7.5kw, 3,600 hollow blocks per shift, and a straightforward control panel, it matched her needs perfectly.
The results:
- Hollow block output jumped from 800/day (old manual press) to 3,200+ blocks per shift
- Fulfilled the housing developer contract on time, and took on a second contract within 2 months
- Staff learned to operate the machine in 2 days — YG provided a video tutorial and WhatsApp support during setup
- Machine downtime: near zero over the first 6 months of operation
Maria’s feedback:“I was nervous about buying from overseas, but the YG team answered every question. The machine arrived, my guys set it up in one afternoon, and we were making blocks the next morning. Best investment I’ve made for this business.”

Frequently Asked Questions About Semi Auto Brick Making Machine
FAQ 1: How Many Bricks Can a Hydraulic Brick Making Machine Produce Per Day?
YG’s lineup produces between 15,000 and 24,000 standard bricks per 8-hour shift, depending on the model. Hopper versions produce roughly 30% more than non-hopper versions. For hollow blocks, output ranges from 2,400 to 3,600 per shift. Running two shifts can double daily output.
FAQ 2: How Many Workers Do I Need to Operate the Machine?
Every YG model operates with 2-3 workers — one to feed material (or just monitor the hopper), one to run the controls, and one to stack finished bricks. This is a significant reduction compared to manual molding crews of 5-8 people.
FAQ 3: Can the Machine Run on a Generator?
Yes. The YG4-35A series draws just 4.8kw, and even the top model (YG4-40A) only needs 7.5kw. Most standard diesel generators at construction sites can handle this without issue. No heavy electrical infrastructure required.
FAQ 4: What Raw Materials Do I Need?
The standard mix includes cement, sand, fly ash, and stone dust with water. Exact ratios depend on your target brick strength and local material availability. YG provides mixing guidelines with every machine purchase and can help optimize your formula based on your local materials.
FAQ 5: How Long Does It Take to Receive the Machine After Ordering?
For standard models, YG typically ships within 15-20 days after order confirmation. Shipping time depends on your destination — Southeast Asia usually takes 10-15 days by sea, East Africa 25-35 days. YG handles export packaging and provides tracking throughout transit.
