PP Stretched Strip Production Line: Technical Specification Guide
PP stretched strips are the primary raw material for polypropylene geogrids. The quality of these strips directly affects the tensile strength of the finished geogrid. Choosing the right production line is essential for consistent output.
Key Specifications
| Parameter | Entry Level | Production Grade |
|---|---|---|
| Screw diameter | Ø100mm | Ø140mm |
| L/D ratio | 28:1 | 30:1 |
| Motor power | 55 kW | 75 kW |
| Output | 3-4 tons/24h | 5-8 tons/24h |
| Strip width | 10-25mm | 10-30mm |
| Line speed | 10-100 m/min | 10-150 m/min |
The Two-Stage Stretching Process
Single-stage stretching produces uneven strip orientation. Two-stage stretching is the industry standard for quality production. The first stage aligns the molecular structure at a lower stretch ratio. The second stage applies a higher ratio to achieve final mechanical properties. This produces strips with uniform strength across the full width.
Component Quality
- Screw: 38CrMoAlA nitrided steel, HV≥740
- Gearbox: ZLYJ280-16
- Heating: 6-zone ceramic, PID controlled ±1°C
- PLC: Mitsubishi FX series
- Inverter: Delta VFD
Revenue Potential
At 5-8 tons/day and current PP strip market prices ($2,500-3,500/ton), a single production-grade line generates $12,000-$28,000 weekly revenue at full capacity.
