Extrusion or extrusion in the manufacture of metalloprokata
Supplier KMZ offers to buy at cost-best price different types and sizes of extruded metal. Supplier guaranteed product delivery at any address specified by the consumer.
Extrusion or extrusion is the process by which can be obtained in long straight metal parts. Cross-section, which can be obtained vary from solid round, rectangular, to L-shaped, T — shaped, tubular and many others. Extrusion is done by squeezing metal in a closed cavity through a tool, called a stamp, which is set usually by a hydraulic press, horizontal design.
The extrusion process
Extrusion produces with the workpiece compressive and shear forces. While extrusion takes place, the stress state of a comprehensive uneven compression, which makes high deformation possible without tearing the wrought metal. Cavity that contains the source material, covered with a wear-resistant material. This allows the matrix to withstand high radial loads that are created when material is ejected from the stamp.
Extrusion often minimizes the need for secondary processing, so using this process we can produce a wide range of cross-sections. Minimum wall thickness for steel sections is about 3 mm, and for aluminum or magnesium of about 1 mm.
To buy at cost-effective price from the manufacturer of extruded profiles of the various grades of metals and alloys in a wide range of cross section offers KMZ. Supplier guaranteed timely delivery of products anywhere in. set by the client.
The types of extrusion
Cold extrusion, a process performed at room or slightly elevated temperature. This process can be used for most materials in the presence of very durable tools that can withstand the stresses created by extrusion. Examples of metals that can be cold extruded are lead, tin, aluminum alloys, copper, titanium, molybdenum, vanadium, steel. Examples of parts that are subjected to cold extrusion, are collapsible tubes, aluminum cans, cylinders, gear blanks.
The advantages of cold extrusion:
• Does not oxidation.
• Good mechanical properties due to severe cold working as long as the temperature created are below the recrystallization temperature.
• Good surface finish with the use of appropriate lubricants.
Hot extrusion is done at fairly high temperatures, approximately 50 to 75% of the melting temperature of the metal. The pressure can range from 35 to 700 MPa. Due to the high temperatures and pressures and its negative impact on the lifespan of a die and other components require good lubrication. For high temperature hot extrusion, the glass powder. Typical parts produced by hot extrusion are trim parts used in automotive, construction, elements, window frames and railings, and structural parts of the aircraft.
