Product Application: Ceramic salt cores are primarily used in the casting process of liquid forging aluminum alloy pistons. By forming cavities inside the piston, ceramic salt cores help achieve an internal cooling structure for the piston. Features: High Strength: By adding ceramic additives, ceramic salt cores achieve high strength, enhancing their ability to withstand high temperatures and pressures of aluminum liquid. High Density: Multiple granulation techniques are employed to achieve high density in ceramic salt cores, contributing to the overall quality of the castings. Low Linear Expansion Coefficient: Through innovative sintering techniques, ceramic salt cores achieve a low linear expansion coefficient, reducing the impact of thermal expansion on aluminum alloy pistons. Ceramic salt cores are typically used in the casting of liquid forging aluminum alloy pistons. Compared to traditional salt cores, ceramic salt cores meet the requirements of high-pressure casting processes for salt cores by increasing ceramic additives, using multiple granulation techniques, and innovative sintering techniques to achieve high strength, high density, and low linear expansion coefficient performance.
Product Application: Forming of complex cavities inside aluminum castings. Features: 1. Compared to ring-shaped piston salt cores, irregular-shaped salt cores, through optimized process upgrades, can produce salt core products of any shape. 2. Irregular-shaped salt cores have higher strength than ordinary piston salt cores. 3. Compared to sand cores and ceramic cores, they are easier to clean and have better surface finish. 4. Widely applicable in the forming of cavities in aluminum alloy products. (1) New salt cores applied to all lightweight castings' internal cavities. Advantages: Currently, most lightweight castings use resin sand cores to form complex internal cavities. During later cleaning, sand sticking may occur locally, making it difficult to clean the internal cavities, which is an unavoidable technical problem. The development of new salt cores can easily solve the problem of difficult sand cleaning in castings. Salt dissolves in water, and only water flushing is needed to meet the technical requirements for removing internal core sand. The use of salt cores in the piston field is already a very mature technology. The new salt core is an extension of piston salt core technology. (2) New salt cores applied to difficult-to-machine areas of injection-molded products. Advantages: For products with difficult-to-machine areas in the later stages of injection molding, new salt cores can be used to directly form the parts that need to be machined later. Place the salt core in the mold before injection molding. This eliminates the technical difficulties of difficult machining in the later stages.
