Extrusion presses are a type of press that metalworkers and other manufacturers use to extrude parts and products. Extrusion pressing is a process during which the press pushes a die through a material in order to create a fixed cross-sectional profile.
Extrusion presses vary in a few ways. These include: by their working temperature (hot extrusion or cold extrusion), by their position (vertical or horizontal), by their driving force (hydraulic or mechanical), by their load type (hydrostatic or variable), by their stroke length, and by whether they use direct or indirect force.
Direct extrusion is when the extrusion press holds the die still while moving the ram towards it, while indirect extrusion is when the ram stays still while the machine moves the die towards it. Indirect extrusion presses work best with hard metal alloy products, like vehicle parts. Meanwhile, direct extrusion presses work better with materials like copper.
Extrusion presses have nearly endless applications. Manufacturers may use them to create anything from pipes for plumbing to gaskets used on airplanes. Extrusion presses are especially well-suited to shaping aluminum parts and products.
Extrusion presses offer tight tolerances, high precision results, variability and efficiency. To learn more, check out one or more of the extrusion press manufacturers and service providers we have listed on this page.
