Choosing the right manufacturing technology is the most critical decision when setting up a precast concrete plant. Two technologies dominate the market: Suspension Roller and Vertical Vibration Casting.
In this article, we’ll compare these two methods across four key dimensions to help you decide which is best for your business.
Choosing the right manufacturing technology is the most critical decision when setting up a precast concrete plant. Two technologies dominate the market: Suspension Roller and Vertical Vibration Casting.
In this article, we’ll compare these two methods across four key dimensions to help you decide which is best for your business.
1. Working Principle
- Suspension Roller (Roller Suspension): This method uses a rotating roller shaft to support the pipe mold. As the mold rotates at high speeds (60-900 RPM), centrifugal force and the pressure from the roller compact the dry-hard concrete against the mold wall.
- Vertical Casting: The mold stands vertically, and concrete is fed from the top while high-frequency vibrators or a pressing head compact the material.
2. Quality and Finish
- Suspension Roller: Known for producing pipes with an extremely smooth inner surface. This is a massive advantage for sewage and drainage pipes as it improves flow capacity. The high-speed rotation ensures high density and low water absorption.
- Vertical Casting: While also strong, the inner surface may not be as smooth as roller-suspended pipes. However, it is excellent for producing very large diameters (over 2500mm).
3. Production Efficiency and Range
- The 600-1200mm Sweet Spot: For the most common municipal pipe sizes (600mm to 1200mm), the suspension roller machine is incredibly efficient. It allows for quick mold changes and continuous production.
- Joint Types: Suspension roller machines are highly versatile, easily producing Flush joints, Tongue & Groove, and Bell & Spigot (Socket) joints with precision.
4. Investment Cost (ROI)
- Suspension Roller: Generally requires a lower initial investment compared to fully automated vertical casting lines. It is easier to maintain and requires fewer highly specialized technicians, making it ideal for growing factories.
- Vertical Casting: Highly automated but comes with a much higher price tag and complex maintenance requirements.
Summary Comparison Table
| Feature | Suspension Roller Machine | Vertical Casting Machine |
| Inner Surface | Mirror-smooth | Standard |
| Best For | 300mm – 2400mm pipes | Large-scale/Jumbo pipes |
| Operation | Simple / Semi-auto | Fully Automatic |
| Initial Cost | Affordable (High ROI) | High |
| Joint Quality | Excellent for Bell & Spigot | Good |
