Molding Powder Metal Parts - Powder metal materials are molded (compacted) under high pressure using large-tonnage presses. Powder metal press size requirement is generally a function of the horizontal cross-sectional area of the part being pressed. Tooling is made to form parts to the net or near-net shape, minimizing the need for secondary machining and virtually eliminating wasted material associated with competing processes. Liberty Pressed Metals engineers will work with you to design and build parts that can be made using PM tooling.
