(example: casting and cooling line), passes a fabric filter and then transfers a part of the contained heat to the in-coming ambient air by means of a recuperative heat exchanger. Sub- sequently the heated air is directed back into the foundry hall. During this process, the extracted gas does not come into contact with the intake air (an advantage in comparison to rotary air-to-air heat exchangers). 

Vacuum Impregnation Made Easier With Automated 2-Stage Process Ultraseal International is living up to its global reputation


自动化二步法使真空浸渗更加容易


for being at the forefront of vacuum impregnation technol- ogy with its new two-stage process to be unveiled at GIFA 2015 in Düsseldorf, Germany. Scientists at the company have revolutionized the design and eliminated one of the three stages of the vacuum im- pregnation process without compromising quality. Called the R-FL-Duo, it has a much smaller footprint


on the factory floor than a conventional vacuum impregna- tion process. It uses less energy, produces less waste and is fully automated with the use of robotics. Te machine is ide- ally suited to single-part processing but, with some configu- ration, multi-parts can also be processed. “Once again Ultraseal International is delivering more benefits to customers with an exciting advance in the fight against porosity in cast metal parts,” said Gary Lloyd, managing director, Ultraseal International. “Our latest in- novation is truly ground-breaking – our two-stage vacuum impregnation process offers all of the quality of Ultraseal’s recycling sealant technology with added advantages in space and cost.” Visitors to GIFA 2015 can see the new R-FL-Duo,


complete with robotic handling, at the Ultraseal stand in Hall 11 F26 at the exhibition in Düsseldorf, Germany from June 16-20. Vacuum Impregnation with porosity sealants is an im- portant post-casting process for diecasters because it offers


在即将于德国杜塞尔多夫举办的GIFA 2015展 上,Ultraseal International公司将发布世界领先的新 的二步法真空浸渗技术,它无愧于享有的全球声誉。 公司的科学家们已经彻底改革了设计,去掉了真空浸 渗三步工艺中的一步,而且不影响质量。 该设备称为R-FL-Duo,它在铸造厂地面上的占地比 传统的真空浸渗设备要小的多。它使用的能源更少,产 生较少的废弃物,使用机器人实现了全自动化。该设备 非常适于单件铸件的加工,但是,做一些配置后,也可 以加工多个铸件。 “Ultraseal International公司在防止铸件产生孔隙 方面取得了令人振奋的进步,又一次为客户带来了更多 的利益,”公司总经理Gary Lloyd说:“公司的最新 创新成果是真正具有里程碑意义的,由于具备了空间 和成本的更多优势,我们的二步法真空浸渗工艺拥有 Ultraseal循环密封技术的全部品质。”GIFA 2015的参 观者将会看到具有全自动化处理技术的新R-FL-Duo设 备,Ultraseal公司展位号是Hall 11 F26。 多孔密封剂的真空浸渗技术是压铸企业的一项重要的 后处理工艺,它能为铸件的孔隙问题提供可靠和永久的 解决方案。
