10 Critical Questions to Ask Before Buying a PTFE Extrusion Line
Introduction: Making Informed PTFE Extrusion Equipment Decisions
Purchasing a PTFE extrusion line requires careful evaluation of material properties, production requirements, and equipment capabilities. This guide examines the key technical and operational factors that determine successful Teflon extrusion outcomes.
Core Considerations for PTFE Extrusion Systems
1. Material Compatibility and Processing Requirements
Evaluate your PTFE resin specifications against these extrusion parameters:
| Material Property | Extrusion Impact | Optimal Range |
|---|---|---|
| Melt Flow Index | Screw Design | 0.5-2.5 g/10min |
| Particle Size | Die Land Length | 150-250 μm |
| Compression Ratio | Barrel Zones | 2.5:1 to 3:1 |
2. Throughput Capacity and Line Configuration
Modern PTFE extruders typically feature:
- 30:1 L/D ratio screws for uniform melt
- Multi-zone temperature control (±1°C accuracy)
- Post-extrusion calibration baths
Technical Specifications Comparison
| Parameter | Entry-Level | Industrial Grade |
|---|---|---|
| Output Capacity | 15 kg/hr | 45 kg/hr |
| Tolerance | ±0.2 mm | ±0.05 mm |
| Pressure Range | 20-40 MPa | 50-80 MPa |
