When manufacturing precision components, choosing between литьё под давлением 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
| Фактор | Литье под давлением | Литье под давлением |
|---|---|---|
| Материал | Metal (Al, Zn, Mg) | Инженерные пластики |
| Вес | Heavier | Lighter (40-70% reduction) |
| Стоимость оснастки | 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)
Преимущества материала
Engineering plastics offer advantages over die cast metals:
- Corrosion resistance — 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

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
When does Die Casting vs Injection Molding: Material and Process Selection Guide make sense?
Die Casting vs Injection Molding: Material and Process Selection Guide makes sense when the part volume, material choice, geometry, and repeatability needs justify mold design and tooling investment.
What design factors matter most for Die Casting vs Injection Molding: Material and Process Selection Guide?
На качество литой детали влияют такие факторы, как толщина стенок, ребра, выступы, угол наклона, расположение литника, усадка, линия разъема и выталкивание.
Какая информация необходима перед изготовлением пресс-формы?
Поставщик должен подтвердить 3D-модель, материал, предполагаемый годовой объем, требования к внешнему виду, допустимые отклонения, а также любые требования к сборке или функциональным испытаниям.
What is the biggest risk in Die Casting vs Injection Molding: Material and Process Selection Guide?
Наибольший риск заключается в утверждении инструментария до того, как поведение материала, усадка, течение и функциональность детали будут полностью проверены в условиях реального применения.
