[0002] Core shooters utilize coated sand core-making technology and are suitable for both hot and cold core box processes. They operate by injecting a core sand mixture containing a thermosetting resin into a heated core box. The sand core is preheated and rapidly hardened to a desired thickness (typically 5-10 mm) within the core box. The core is then removed, resulting in a smooth, dimensionally accurate, high-quality finished sand core. Core shooters are widely used in the production of castings in the automotive, construction machinery, shipbuilding, high-speed rail, and aerospace industries. In particular, in the automotive industry, core shooters are used to produce sand cores for automotive components such as subframes to meet the demands of castings with complex internal structures.
