High accuracy, seamless, fine-bore tubes used in complex aircraft heat exchangers. Tubes can be manufactured to lengths of over 1 metre with highly consistent wall thickness and excellent surface finish.
The alloys used provide ductility, even after extrusion, allowing 90° bends to be performed and easy swaging of the tube ends on assembly.
In waveguides used in missile guidance systems or medical scanners, sharp corners can be achieved in deep, parallel 'hobbed' holes - a very cost effective alternative to traditional spark erosion or investment casting techniques. Excellent tolerances and repeatability are typical characteristics on an impact extrusion.
We have a long tradition of supplying defence organisations throughout the world with parts used in very high specification such as weapons guidance, practice rounds, distress signal flares, weapon effects simulation and decoy flares. High volume applications such as prectice rounds and decoy flares are ideally suited for our mass proiduction techniques. Throughout, we can maintain the consistent repeatability of the close toleranced dimensions required.
Very thin-walled detonator cases with wall thicknesses as low as 0.05mm are possible with the impact extrusion. Unlike a deep drawn case, an impact extruded case can have its base much thicker than the wall with highly accurate features, such as cap indentations, formed in.
Impact extrusion offers designers a vast range of new possibilities when faced with unusual or difficult requirements. The addition of secondary CNC machining facilities enable us to compliment our primary process to produce unique solutions to these problems.
