CONFIGURATION GUIDE
Single Die vs Dual Die — Which Configuration Do You Need?
All SW small extrusion blow molding machines are available in single-die (S prefix) and dual-die (2S prefix) configurations. Choose based on your target output and container volume.
- One die head — one parison per cycle
- Suitable for larger containers (5L–15L)
- Lower upfront cost, simpler maintenance
- Ideal for start-ups or small-batch production
- Compact footprint, easier installation
- Two die heads — two parisons per cycle
- Up to 2× the output vs single die
- Suitable for small containers (0.5L–5L)
- Higher production efficiency, lower cost per unit
- Preferred for high-volume mass production
| Container Volume | Recommended Config | Typical Output | Recommended Model |
|---|---|---|---|
| 0.5L | Dual Die | 950×2 pc/h | SW-2S1L |
| 2L | Dual Die | 800×2 pc/h | SW-2S2L / SW-2S2L/T |
| 5L | Single or Dual | 700~700×2 pc/h | SW-S5L / SW-2S5L |
| 12–15L | Single Die | 600 pc/h | SW-S12L / SW-S12L/T |
