Metal sealing gaskets are usually manufactured by machining or stamping, not by die casting. The process paths and applicable situations of the two are different.
Machining is the precision processing of metals by lathes, milling machines, grinders and other equipment, which is used to produce high-precision metal parts. For metal sealing gaskets, especially those with complex shapes and high precision requirements, machining can provide very high precision and surface quality. Select suitable metal materials, such as stainless steel, aluminum alloy or copper alloy. Use lathes, milling machines and other equipment to process the fine parts of the gasket, such as the shape, aperture, inner and outer circles. The surface finish is further improved by grinding, polishing and other processes to ensure the sealing performance. This process is suitable for metal sealing gaskets that require high precision and complex designs, and is widely used in high-end equipment such as aerospace, automobiles, and hydraulic systems.
For mass-produced metal gaskets, stamping is a common manufacturing method. The metal sheet is pressed into shape under the action of the mold, which can efficiently produce sealing gaskets of various conventional shapes. Use metal sheets such as stainless steel, aluminum alloy, copper and other materials. The mold is designed according to the shape and specifications of the gasket. The metal sheet is fed into the stamping machine and pressed into the shape of the gasket through the die. The stamping process is suitable for mass production of metal sealing gaskets of conventional shapes and is widely used in automobiles, mechanical equipment and piping systems.
Die casting is mainly used to produce metal parts with complex shapes and larger structures, but it is generally not used to manufacture metal sealing gaskets. Die casting is a process that injects molten metal into a mold and uses pressure to quickly solidify and form it. It is suitable for materials such as aluminum alloys and zinc alloys. Although die casting can produce parts with complex geometric shapes, since metal sealing gaskets are usually thin and simple structures, die casting is generally not used for the production of such parts.
Metal sealing gaskets are generally produced by machining or stamping processes, and die casting is more suitable for manufacturing larger and more complex metal parts. Stamping is suitable for mass production of gaskets of conventional shapes, while machining is suitable for metal sealing gaskets with high precision and complex shapes.
