Extrusion
Elmet Technologies provides industry-leading extrusion services for a wide range of refractory metals and high-performance metals. Through a fully-integrated manufacturing process, we regularly procure the material, manufacture the billet, extrude it, and finish it to precise customer specifications with fast delivery times. We provide a wide range of finishing processes to suit nearly any application, including heat treatment, cleaning, straightening, machining, cutting, and more.
We assist our customers by solving their most demanding material processing and fabrication challenges. By combining state-of-the-art extrusion technology with an extensive knowledge in the processing and metallurgy of a wide spectrum of metals, we are unique in our ability to extrude nearly any metal in nearly any size range. Our highly skilled team of engineers and metallurgists can assist with the processing of materials to meet your exact performance requirements.
Extrusion for High-Performance MEtals
Elmet Technologies’ Coldwater, Michigan, facility is home to advanced extrusion equipment that combines cutting-edge computerized controls with ultra-precise hydraulics. Our world-class 5,000 metric ton (5,500 ton) extrusion press achieves processing speeds that range from 0.01″ to 12″ per second.
Advanced processing equipment allows us to manufacture extrusions with diameters ranging from 152 to 457 mm (6 to 18 inches). By preheating billets up to 1925°C (3500°F) via gas-fired or inert atmosphere induction furnaces and meticulous control of ram speed, we offer unique capabilities in metal processing. These capabilities allow us to deliver high-performance solutions for precise customer requirements.
