Nylon is one of the most widely injection molded engineering thermoplastics, but its unique processing characteristics—moisture sensitivity, narrow melting range, and rapid crystallization—require specific knowledge to achieve consistent quality.
Material Preparation: Drying is Critical
| グレード | Drying Temp | Time | Target Moisture |
|---|---|---|---|
| PA6 | 80°C | 4-8 hrs | < 0.10% |
| PA66 | 80°C | 4-8 hrs | < 0.10% |
| PA6 GF30 | 80°C | 4-6 hrs | < 0.05% |

処理パラメータ
| パラメータ | PA6 | PA66 | PA6 GF30 |
|---|---|---|---|
| 溶融温度 | 240-270°C | 270-300°C | 250-280°C |
| 金型温度 | 60~90°C | 80-100°C | 80-100°C |
| Injection Pressure | 70-120 MPa | 80-140 MPa | 80-150 MPa |

Mold Design for Nylon
Gate Design
Gate size should be 50-75% of wall thickness. Position gates to ensure uniform flow and minimize fiber orientation issues in glass-filled grades.
愚痴
Proper venting is essential—nylon’s low viscosity means it fills quickly and can trap air. Vent depth of 0.01-0.03mm is typical.
よくある不具合と解決策
| 欠陥 | Cause | 解決策 |
|---|---|---|
| Splay/Silver Streaks | Moisture | Dry material properly |
| Brittle Parts | Overheating | Reduce melt temp; verify drying |
| 反り | Uneven cooling | Adjust mold temp; optimize gate |
| Flash | Low viscosity | Reduce injection speed |

Post-Molding Handling
Moisture Conditioning
Nylon parts are at their most brittle straight out of the mold. Accelerated conditioning in 50-80°C water for 1-4 hours improves impact resistance and toughness.
