Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying:80 ℃ for 3‑6 h; alternatively 80‑90 ℃ for 6‑8 h to reduce moisture below 0.1%. Extend drying time or adopt high‑temperature vacuum drying under high‑humidity conditions. | Critical operation. Prevent hydrolysis‑induced bubbles, silver streaks and mechanical‑property deterioration. Use immediately after drying or seal and keep warm properly. |
| Melt Temperature | Barrel rear/middle/front:270‑290 ℃; nozzle:280‑300 ℃; general range 270‑290 ℃. | Fine‑tune according to equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | 80‑90 ℃; alternative range 80‑100 ℃. | Proper mold temperature ensures good crystallinity, surface gloss and mechanical performances. Higher mold temperature improves crystallinity for better mechanical properties. |
| Injection Pressure | Adjust per product & mold design | Higher injection pressure may be required for glass‑fiber‑reinforced grade. |
| Injection Speed | Medium‑high speed | Fast filling is beneficial; mold shall be well‑ventilated. |
| Runner & Gate | Gate dimension shall not be excessively small | Nylon solidifies rapidly; gate location and size are critical for filling. |
