Vacuum gives a very big improvement to the quality of die castings.
Top five benefits are:
- Superior cast surface appearance
- Enables excellent paint and plating finishes
- Reduces number of castings rejected for surface defects
- Minimises porosity
- Gives savings in manufacturing costs
This comprehensive technique was first used in 1991 at a
commercial zinc die-casting foundry in UK; since then it has been
successfully applied in aluminium and zinc foundries in UK, China, Canada and USA.
The method uses innovative and fundamental engineering
methods to achieve a very powerful technique that can be applied to all
types of diecasting die with excellent process reliability and low
A key feature of the process is a unique technique for
measuring the vacuum pressure in the mould during each cycle.
Northey Vacuum Pumps and equipment are recommended on
their proven reliability and performance in 24/24 hour 3 shift diecasting
foundry environment with minimal maintenance needs.
