    Extrusion press stem is one important part of aluminium extrusion press 500彩票网安全下载, which transfers the power of the main cylinder on the billet like a column. 


    The stem is an element which transfers the power of the main cylinder on the billet like a column. The stem, which must operate without bending and cracking under a high power needs to bear a pressure of up to 120 kg/mm2depending on the size of the press and the performed application. Therefore, the centering during the operation must be performed properly.

    AISI H13(1.2344) is the most frequent used hot tool steel for the stem. This steel is brought to Rockwell C45-50 hardness by applying heat treatment. Maintaining this hardness depends on the consistency of the operating temperature and on avoiding internal stresses.


    The stem transfers the power of the main cylinder onto the billet, via a dummy block. Stems are subject to high pressure during extrusion but their working temperature is relatively low as they are not in contact with the billet. A stem must not bend or otherwise deform at the temperature of operation.


    Due to the high pressure and a dangerous environment, it is of great importance to regularly inspect the stem in respect of parallelism between the planes, straightness and surface condition. Uddeholm Machining offers a maintenance program for stems, which includes regular check-ups.

    The Extrusion Stem must withstand the total deformation resistance of the material being extruded.The occurring extrusion loads result in very high compressive and partly bending stresses in the stem.
