SYNOPSIS 摘要

VACUUM FOR DIECASTING

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 cost.

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.

真空技术在压铸方面的应用

真空技术应用于压铸件的生产,使生产出的压铸件质量得到了很大的提高。

五大突出优点:

  • 出众的铸件表面质量
  • 使铸件表面的喷漆和电镀效果极佳
  • 减少由于铸件表面缺陷造成的废品
  • 把气孔缺陷降到最低
  • 节省机加工费用


这项技术最早应用于1991年,在一家生产锌合金压铸件的英国铸造厂获得了成功。随后该项技术在英国和中国得到了广泛的应用,特别适合生产锌合金和铝合金压铸件的铸造厂使用。


该项技术把基本的工作原理和创新结合在一起,创造了一种能够应用在各种压铸件生产上,具有可靠性,并且费用低廉的新技术。


该项技术的唯一关键点是怎样测量铸型内的真空压力。


北方牌真空泵和设备被证明在压铸厂使用具有稳定的可靠性和优良的使用性能,适合24小时或24小时3班倒生产,维修费用低廉。
