[0002] Iron castings generally refer to objects cast with iron. They are the most commonly used metals and are made of molten iron. The production and application of cast iron parts are of great significance to improving the quality of castings, promoting the industrial upgrading of equipment manufacturing industry and increasing the localization rate. However, cast iron parts need to be processed secondary after production and processing. Cast iron parts need to be positioned and fixed during production and processing.
