When manufacturing precision components, choosing between 사출 성형 and die casting depends on material requirements, production volume, and part complexity. Both processes offer unique advantages for different applications.
Process Overview
Die casting injects molten metal (aluminum, zinc, magnesium) into steel molds under high pressure. Injection molding does the same with thermoplastics like nylon, POM, or PEEK.
Key Differences
| 팩터 | 다이 캐스팅 | 사출 성형 |
|---|---|---|
| 재료 | Metal (Al, Zn, Mg) | 엔지니어링 플라스틱 |
| 무게 | Heavier | Lighter (40-70% reduction) |
| 툴링 비용 | Higher ($30k-$150k) | Lower ($10k-$50k) |
| Cycle Time | 15-60 seconds | 10-45 seconds |
When to Choose Injection Molded Plastics
Nylon injection molding is preferred when:
- Weight reduction is critical (automotive, aerospace)
- Electrical insulation is required
- Chemical resistance to specific environments
- Lower tooling investment for mid-range volumes
- Design requires complex features (undercuts, threads)
소재의 장점
Engineering plastics offer advantages over die cast metals:
- 내식성 — no rust or oxidation
- Design freedom — snap-fits, living hinges, integrated fasteners
- Vibration damping — quieter operation
- Lower secondary operations — no machining or surface treatment needed
