Magnesium alloy extrusion process: heating ingot → primary extrusion → cutting intermediate billet → heating → secondary extrusion → artificial aging → stretch straightening → cutting head and tail sampling → roll straightening → manual straightening → inspection → cutting and printing → Oxidation coloring→finished product inspection→packaging→warehousing. Process features: magnesium alloys are only allowed to be heated in an air resistance furnace; in order to prevent combustion, the maximum heating temperature of various alloys is 470 °C; the maximum extrusion speed is 20m/min, which is faster than hard aluminum alloys, but only soft alloys about 1/3 of that; the shrinkage of magnesium alloy extruded material is larger than that of aluminum alloy, and the size of the die should be increased accordingly. The production process covers investment casting, permanent mold casting, die casting, sand casting, forging as well as CNC machining and stamping.

    What is the Meaning of CNC in English?

    CNC is an acronym for Computer Numerical Control. It refers to a manufacturing process that uses computerized controls to operate machinery, such as lathes, mills, routers, and grinders. The technology behind CNC takes precise measurements and coordinates from a computer-aided design (CAD) file and converts them into specific instructions for the machine to follow. With CNC, manufacturers can create highly accurate and complex parts and components with greater efficiency and consistency than traditional methods.   The history of CNC dates back to the 1940s, when the United States Air Force began developing the technology to improve the accuracy and consistency...

    Aluminum Alloy Die Casting: The Efficient Way to Create Precision Parts

    Aluminum alloy die casting is a highly efficient manufacturing process that is used to create high-quality, precision parts with excellent dimensional accuracy and surface finish. This process involves injecting molten aluminum alloy into a steel mold or die using high pressure and high speed. Once the aluminum alloy solidifies, the die is opened, and the cast part is ejected. This process is repeated many times to produce large quantities of parts that are identical in shape and size.   One of the significant advantages of aluminum alloy die casting is its ability to produce complex shapes with precision and consistency....
