Manifold Only System
Heated Manifold
- Distributes melt from machine nozzle
Cold Runner Channels
- Final path to cavities
Standard Gates
- Edge gate / pin gate / submarine gate
Heaters + Thermocouples
- Only for manifold (not nozzles)
Types of Manifold-Only Systems
• Direct Feed Manifold + Cold Gate
- Manifold feeds directly into cavity via cold gate
? Simple, low cost
• Manifold + Sub Runner System
- Manifold distributes to multiple cold runners
? Used in multi-cavity molds
• Hybrid (Manifold + Hot Nozzle Mix)
- Some cavities hot, some cold
? For cost-performance balance
