Double Hook Shot Blasting Machine for Aluminum Cylinders

Tackling Industry Challenges: Shot Blasting Technology for Aluminum Cylinder Blocks

    For automotive aluminum die castings (e.g., engine cylinder blocks), how to avoid workpiece deformation during shot blasting and clean the dead corners of the inner cavity?

    For die castings, as a manufacturer with full production capacity, we use variable-frequency speed-regulating shot blast wheels to precisely control the impact force of steel shots, and calibrate the blast angle between 10°~80° to cover the inner cavity. We offer custom-shaped tooling and fixtures made to customer drawings, ensuring even force distribution on workpieces on the turntable for comprehensive cleaning.

Case Study: Shot Blasting Cleaning Project for Automotive Engine Cylinder Blocks

    A leading automotive component manufacturer required pre-coating treatment for large batches of aluminum cylinder blocks, with a specified surface cleanliness of Sa2.5 and strict control over workpiece deformation.

Customized Engineering Design & Delivery Logic As a direct factory, we provided them with a turnkey one-stop solution:

• Non-Standard Design: Leveraging our custom engineering capabilities, we developed a double-hook synchronized operation system that fits perfectly with the existing factory layout, eliminating the need for additional customer modifications.

• Precision Blast Modelling: Using 3D simulation, we calibrated the blast wheel angles to verified positions of 35° and 75°, with each unit’s rated shot flow set at 300kg/min.

• Intelligent Electrical Integration: The system operates on 380V power and is integrated with a Siemens PLC, enabling fully automated cycle production.

The solution achieved full coverage cleaning with dust emissions consistently kept below 10mg/m³, fully demonstrating our robust capability to provide custom solutions based on customer drawings.
