In today’s world of infrastructure, the automated extruded curb machine is quickly taking the place of old-school manual methods. Unlike the slow and labor-intensive process of hand-molding, this machine can boost construction efficiency by over five times! It works by using the extrusion principle to lay down concrete or asphalt directly and continuously onto the prepared sub-grade.
This cutting-edge construction technique greatly lessens the need for a big team of skilled workers. For contractors, embracing YG Machinery’s extrusion technology means faster project timelines and better profit margins. In areas like South Africa, the Middle East, and Southeast Asia, this equipment has become essential for raising the standards of road construction.

Deep Dive: How an Extruded Curb Machine Works
The core of an extruded curb machine is its powerful extrusion system. Once the material makes its way into the hopper, a high-efficiency auger or plunger pushes it into the forming mold. This process subjects the material to significant pressure, which is crucial for achieving the high levels of concrete compaction needed for engineering standards.
By swapping out different curb molds, contractors can create a variety of shapes with the same equipment. The hydraulic systems from YG Machinery provide stability during movement, resulting in smooth and visually appealing curb lines.
Concrete Mix Design for Optimal Extrusion
| Parameter | Recommended Value | Why it Matters |
| Concrete Slump | 10mm – 30mm | Prevents curb collapse while ensuring smooth finish. |
| Water-Cement Ratio | 0.35 – 0.45 | Ensures high concrete compaction and strength. |
| Aggregate Size | < 20mm (Crushed stone) | Prevents auger jamming in the extruded curb machine. |
| Sand Ratio | 35% – 40% | Provides the necessary “cream” for a smooth surface. |
| Compressive Strength | 20MPa – 30MPa | Prevents curb collapse while ensuring a smooth finish. |

Technical Advantages of the Extruded Curb Machine

Superior Daily Output and Speed
A high-performance extruded curb machine can consistently lay 500 meters or more per day. This daily output capacity is unattainable by manual crews, giving contractors the confidence to meet tight deadlines.
Reduced Labor and Management Costs
Traditional curb installation often requires a team of 8–10 people. In contrast, operating a slipform curb machine requires only about 3 operators. This not only cuts payroll expenses but also simplifies onsite personnel management.
Structural Durability and Resilience
The high pressure from mechanical extrusion leaves virtually no internal voids in the curb. This dense structure effectively resists impacts from vehicles and erosion from natural elements. YG Machinery equipment is typically fitted with a reinforced hydraulic drive system, maintaining consistency even under harsh working conditions.
Wide Applications and Global Success Stories

Highways and Urban Arterials
In large-scale road projects, the extruded curb machine is widely used for the rapid laying of drainage gutters and edge curbs. It adapts perfectly to various sub-grade preparation conditions, ensuring precise linear alignment.
Commercial Parking Lots and Industrial Parks
Many clients look for an extruded curb machine for sale to handle private commercial projects. The machine can turn precisely in tight spaces, creating neat, curved edges that enhance the overall project aesthetics.
Case Study: A Leap in Efficiency for a South African Contractor
Mr. Andre, who runs a road and bridge company in South Africa, faced a major hurdle during a 12km project in Johannesburg: the cost of transporting precast sections was astronomical, and installation was incredibly slow.
After switching to a YG Machinery solution, the situation turned around:
- The Solution: Implemented continuous onsite casting using a slipform curb machine with custom molds tailored to local standards.
- Results: Daily production stabilized at 650 meters, and labor costs were slashed by 55%.
- Impact: Andre delivered the project 15 days ahead of schedule and secured two subsequent government contracts due to the superior finish quality.
Optimizing the Performance of Your Extruded Curb Machine

The material mix is the most critical factor for a successful finish. We recommend a concrete slump between 10mm and 30mm. If the mix is too dry, surface cracks may appear; if too wet, the curb may collapse under its own weight.
Furthermore, regular inspection of the auger for wear is essential. YG Machinery suggests a deep inspection every 5,000 meters of paving. Keeping the machine clean and replacing hydraulic oil on time are the secrets to extending the equipment’s lifespan.
