AMETEK Foundry Products' next generation of high-performance filter cups were showcased alongside the top new investment casting technologies during the recent 56th Annual Investment Casting Technical Conference & Expo in Indianapolis, Ind. The CerraFlex TorrentFlow® filter cup incorporates a unique refractory coating that effectively increases the working temperature threshold by 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,” said 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 and pouring cone pair to deliver an optimal filtration area increase of up to 78% over traditional filter cup designs. Prior to this 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, according to Hitchings.
