Plastic injection molding hot runner system
Hot runner is a set of temperature control heating-device, installed in the plastic injection mold, it is part of the mold. A Hot Runner System is used to maintain a molten flow of plastic from the injection molding machine nozzle to the gate in a plastic injection mold.
Advantages of a Hot Runner System
The critical areas of performance for a hot runner system are:
Advantages of a Hot Runner System
- Reduce cycle times.
- Remove cold runner that would be either scrap or require regrind.
- Improve part consistency and quality.
- Reduced gate mark.
- Reduce injection pressure.
- With valve gates, makes sequential filling and family of parts molds possible.
- Offers more process control for fine tuning.
The critical areas of performance for a hot runner system are:
- Precise temperature control of the molten plastic to avoid degradation.
- Balanced flow to all cavities giving even filling of parts.
- Nozzle sizing for maintaining sufficient molten material flow.
- Gate detail to correctly fill the part but also shut the gate off after filling ensuring.
- minimal drool and short cycle time.
- No traps or areas of flow hesitation to ensure quick color change and prevent.
- material degradation.
- Minimum pressure drop across the hot runner system.
- Reasonable melt residence time.

Hello,
We have not made any temperature control heating-device parts specifically, but that is well within our capability. Please contact us for a free quote if you are interested. this is best post and advantages of hot runner system are good. so I am waiting your next post.
