Applications
Automotive Industry
Component Cleaning and Surface Preparation: In the automotive manufacturing process, numerous components such as engine blocks, chassis parts, and suspension components require thorough surface treatment. The roller conveyor shot blasting machine effectively removes casting sand, rust, and other contaminants from these parts, ensuring a clean surface for further machining, painting, or coating. For example, engine blocks often have rough surfaces after casting, and shot blasting smooths them out, improving heat dissipation and the overall performance of the engine.
Enhancing Fatigue Resistance: Shot blasting also imparts compressive stresses on the surface of automotive components, which significantly improves their fatigue resistance. This is crucial for parts like crankshafts and axles that are subjected to high - stress cyclic loading during operation. By increasing the fatigue life of these components, the overall reliability and lifespan of the vehicle are enhanced.
Aerospace Industry
High - Precision Component Treatment: The aerospace industry demands the highest level of quality and precision in its components. The roller conveyor shot blasting machine is used to clean and treat parts made of advanced materials such as titanium alloys and high - strength steels. It removes machining marks, oxidation layers, and other surface imperfections, ensuring that the components meet the strict aerospace standards. For instance, aircraft landing gear components, which are exposed to extreme forces during takeoff and landing, require a flawless surface finish, and shot blasting helps achieve this.
Surface Strengthening for Safety - Critical Parts: Safety - critical aerospace components, such as those in the engine and airframe, need to be highly resistant to fatigue and stress corrosion cracking. Shot blasting introduces compressive stresses on the surface, which act as a barrier against crack initiation and propagation, thereby enhancing the safety and reliability of these components.
Construction and Heavy Machinery
Steel Structure Cleaning and Preparation: In the construction of buildings, bridges, and other infrastructure, steel structures are commonly used. The roller conveyor shot blasting machine is employed to clean the steel surfaces, removing rust, mill scale, and other contaminants. This pre - treatment is essential for applying protective coatings, such as paint or zinc coatings, which prevent corrosion and extend the lifespan of the structures. For example, large - scale steel beams used in high - rise buildings are shot - blasted to ensure a strong bond with the protective coating.
Component Refurbishment: Heavy machinery components, such as hydraulic cylinders, gears, and shafts, often require refurbishment after extended use. Shot blasting is used to remove worn - out surfaces, clean out contaminants, and prepare the components for re - coating or re - machining. This process helps to restore the performance and functionality of the components, reducing the need for costly replacements.
Metal Fabrication and Foundry
Deburring and Edge Rounding: In metal fabrication shops, parts are often cut, drilled, or welded, leaving behind sharp edges and burrs. The roller conveyor shot blasting machine can effectively deburr and round these edges, improving the safety of handling and the aesthetics of the final product. Additionally, it helps to remove any heat - affected zones or surface imperfections caused by the fabrication process.
Casting Cleaning and Surface Finishing: In foundries, castings are typically covered with sand, oxide layers, and other residues. Shot blasting is an efficient method for cleaning these castings, revealing a clean and smooth surface. It also helps to improve the surface finish of the castings, making them suitable for further processing or direct use in various applications.
