Extrusion Wire‑Drawing Processing
Processing temperature, pressure and other parameters shall be optimized according to equipment, product specification and performance requirements.
‑ Processing temperature: general HDPE extrusion range 160‑220°C; fine‑tune according to MFR (1.0 g/10min) and actual equipment. ‑ Screw configuration: single‑screw or twin‑screw extruder; L/D ratio greatly affects plasticizing quality and output. ‑ Cooling & drawing: extruded filaments pass through water bath for cooling and sizing; drawing ratio and final filament denier are controlled by traction rollers. Drawing ratio is critical for filament strength and molecular orientation. ‑ Winding: wind finished filaments onto bobbins.
Extrusion Processing Notes
‑ Melt strength: MFR 1.0 g/10min delivers good melt strength for stable extrusion and filament forming. ‑ Cooling condition: Cooling‑water temperature and stable traction speed are critical for crystallinity, tensile strength and surface gloss of filaments. ‑ Raw‑material drying: HDPE has low moisture absorption. Dry at 60°C for 1 hour to remove surface moisture if stored under high‑humidity conditions.
Injection‑Molding Processing
‑ Melt temperature: 220‑260°C; for higher‑molecular‑weight grades, adopt 200‑250°C. ‑ Mold temperature: 50‑95°C. Higher mold temperature for wall thickness below 6 mm; lower mold temperature for wall thickness above 6 mm. ‑ Injection pressure: 700‑1050 bar. ‑ Injection speed: high‑speed injection recommended. ‑ Runner & gate: runner diameter 4‑7.5 mm; keep runner length as short as possible.
