Beryllium Copper
Chill Vents
Key Properties
Meeting the demands of high-pressure die casting!
The C-Block is NGK’s standard beryllium copper chill vent, developed and manufactured to provide solutions to common die casting issues.
Ventilation and Simplification
With a thermal conductivity five times greater than steel, NGK’s Chill Vent delivers ideal cooling capacity to resolve major aluminum die casting challenges.
Key Properties of NGK Copper Alloys
- Superior thermal conductivity and hardness
- Cooling rate five times faster than steel
- Enables very large cross-sections
- Eliminates aluminum/vent chemical reactions
Compactness – Thanks to its high cooling performance, the NGK C-Block enables optimized die design and reduced mold size.
Efficiency and Cost Effectiveness – The C-Block significantly reduces production costs related to casting rejects and mold wear.
Versatility – NGK Chill Vents are available in a wide range of sizes and in two configurations: for vacuum and non-vacuum casting systems.
Our R&D department is at your disposal to design and manufacture Chill Vents tailored to your specific requirements.
