Newark, DE - For the past 55 years, Investment casting professionals worldwide have eagerly looked forward to the annual unveiling of the latest technical innovations and concepts at the Investment Casting Technical Conference & Exposition, sponsored by the Investment Casting Institute. This year’s show, the 56th, continued that tradition and included the TorrentFlow Filter Cup among the handful of promising new investment casting technologies and best-practices.
AMETEK Foundry Product’s CerraFlex TorrentFlow filter cup, the next generation of high- performance molten metal filter technology, incorporates a unique refractory coating that effectively increases the working temperature threshold several hundred degrees to a new maximum of 3500°F / 1927°C. This refractory composition significantly enhances the rigidity and overall strength of the filter cup, providing for increased pouring times and heavier metal flow.
The TorrentFlow filter concept was developed exclusively for AMETEK by Comanche Technologies and is part of the larger CerraFlex product family that provides increased metal quality and reduced operating costs for investment casting and foundry customers worldwide. “Given the challenging manufacturing landscape we’re currently facing, our goal is to provide investment casters an additional tool for reducing production costs and being more competitive in the global market” notes Jason Hitchings, General Manager of Comanche Technologies.
In addition, the TorrentFlow design incorporates a distinctive interstitial space between the inner wall of the pouring cone and the outer edge of the filter wall that is custom calculated for each cup & pouring cone pair to deliver an optimal filtration area increase of up to 78% over traditional filter cup designs. Prior to this radical design, investment casters could only improve their metal throughput rate by increasing the size of the filter pores or mesh size of their respective filtration material, adds Hitchings.
This increased throughput rate NEVER came at the expense of decreased filter effectiveness, which typically would permit slag and other impurities to pass through the larger pore and mesh openings and into the casting itself. The presence of additional impurities often resulted in defects and other quality problems that forced an entire production run to be scrapped. The TorrentFlow cup design offers users the ability to increase their throughput rate and to not only maintain, but increase, their filtration level. In other words, “to have their cake and eat it too”, concludes Hitchings.
