Open Nozzle Hot Runner · Best Seller
- Technical Features
- Integrated heating and packaging structure for the nozzle head with independent temperature control
- Core Advantages
- Smooth flow path, corrosion- and wear-resistant alloy steel nozzle for extended service life.
- Use Cases
- Over 90% of precision injection molding scenarios can be met without needle valves.
- Core Benefits
- Effectively prevents filament formation, sagging, and nozzle clogging.
Four Key Selling Points
- 1Directly heats the mouthpiece, rather than relying on passive heat transfer.
- 2Maintains melt temperature during injection hold phase, eliminating nozzle clogging issues.
- 3After pressure holding, the nozzle cools to the curing temperature of the rubber compound.
- 4No fiber drag or stringing at the gate during mold opening
Add model
Open Pointed
- Use Cases:Precision plastic components, standard precision injection molding, direct gate molding
- Key Features:Direct injection onto the product surface with adjustable nozzle temperature and easily balanced, controllable mold cavities.
- Key Advantages:Fast thermal response prevents stringing and dripping, ensuring high molding yield.
Needle Valve Series
- VG Series (High-End Connector Housing):Precision-guided valve needle ensures reliable sealing, significantly eliminating gate blush and weld lines while delivering superior gate quality.
- PVG Series (PVC / Corrosive Materials):Optimized for easily degradable and corrosive plastics; temperature control prevents gate burn, supporting a wider range of materials.
