Highly customized metal filter powders are in increasing demand for life-saving medical applications. These specialized materials are used in a variety of medical products, such as porous flow restrictors in ventilators to control oxygen flow and prevent clogs in the system.
AMETEK Specialty Metal Products (SMP) produces filter powders using a highly refined water atomization technology to ensure the highest quality powder that meets the exact requirements of medical filter manufacturers and OEMs. The water atomization process provides the ability to produce bespoke powders in a wide variety of metals, from stainless steels to nickel and cobalt alloys. AMETEK SMPs engineers tailor this process to form highly irregular shapes of powder grains that are critical for medical filter producers. A multitude of other shapes and morphologies can be produced including spherical materials used in Additive Manufacturing. The filtration powders produced by AMETEK SMP are then pressed and carefully shaped by the filter producers to offer precision assistance with flow control in “mission-critical medical applications, such as ventilators.
AMETEK SMPs advanced manufacturing process involves several steps that each have an impact on the morphology of the finished product. Starting from the initial selection of raw materials to processing them into molten metal to water atomizing them into a fine powder, the team works to continuously improve and control the products particle size distribution (PSD) and ensure optimum particle shape for the individual job specification.
Another key advantage AMETEK SMP can offer are extremely short lead times. The facility has the capacity to fulfil urgent orders in as little as two or three days and more standard jobs in just a couple of weeks.
