PA66 BASF A3WG6 Resin
PA66 BASF A3WG6 Resin
Material Introduction: PA66 BASF A3WG6 (Germany BASF) is a high‑performance 30% glass‑fiber‑reinforced PA66 engineering plastic. It features high strength, high rigidity, good heat resistance and dimensional stability, together with favorable electrical‑insulation performance and HB‑grade flame retardancy. Its inherent water‑absorption property will affect dimensional stability and partial performances; strict drying is mandatory before processing.
Main Applications
Automotive industry: Engine‑peripheral parts (intake manifolds, cooling fans), structural components (door‑frame parts, bumper supports), wheels, gears, bearings, oil pipelines and oil reservoirs.
Electronic‑electrical industry: Connectors, coil bobbins, timers, circuit‑breaker covers, switch housings, lamp‑holder housings, electrical‑appliance enclosures and terminal blocks.
Mechanical parts / Industrial fittings: Industrial gears, bearings, pulleys, pump housings, high‑stress technical components, enclosures, sports‑equipment parts (ski‑shoe bases, ice‑skate bases), textile shuttles and pedals.
Other fields: Insulation profiles for aluminum window frames, containers and home‑appliance components.

Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying at 80 ℃ for 2‑4 h; vacuum‑dry at 105 ℃ for 12 h if moisture＞0.2%. | Critical operation. Control moisture content below 0.12%‑0.15% to avoid hydrolysis‑induced bubbles, silver streaks and mechanical‑property deterioration. Use immediately after drying or seal and keep warm properly. |
| Melt Temperature | 275‑280 ℃ for glass‑filled grades; alternative range 280‑305 ℃. | Fine‑tune according to equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | Recommended 80 ℃; optional 80‑90 ℃. Mold temperature affects crystallinity and physical properties. Thin‑wall parts molded below 40 ℃ require annealing for geometric stability due to time‑dependent crystallinity change. | Higher mold temperature delivers better crystallinity and property stability. |
| Injection Pressure | 750‑1250 bar. | Adjust per product & mold design. Higher injection pressure may be required for glass‑fiber‑reinforced grade. |
| Injection Speed | High speed (moderately reduced for reinforced grades). | Fast filling is beneficial; mold shall be well‑ventilated. |
| Runner & Gate | Gate bore ≥0.5*t (t = part wall thickness). Hot‑runner gate size shall be smaller than conventional runner. Minimum diameter for submarine gate:0.75 mm. | Nylon solidifies rapidly; gate location and size are critical for filling. |
| Screw Speed | ‑ | Avoid excessive shear heat. General PA66:30‑60 rpm. |
| Holding Time | ‑ | Depends on part wall thickness. |
