Sandblast Room for Aluminum Extrusion Cleaning

 

  

A sandblast room designed for aluminum extrusion cleaning addresses the unique needs of treating lightweight metal components, which require gentle yet effective surface preparation. Aluminum extrusionsused in automotive body frames, engine brackets, and interior trimoften carry extrusion lubricants, oxidation layers, or die marks that must be removed without compromising material thickness or finish. The rooms design features low-pressure blasting systems (20-50 PSI) using non-abrasive media like plastic beads, walnut shells, or fine glass powder, which clean surfaces while creating a uniform matte finish.  

Key components include a climate-controlled chamber to prevent aluminum oxidation during processing, and a specialized dust collection system that separates lightweight media from aluminum particles for recycling. In automotive manufacturing, these rooms prepare extrusions for anodizing, painting, or bonding, ensuring consistent surface quality across large batches. The modular design allows customization for different extrusion sizes, with overhead conveyors or rotating tables to facilitate 360-degree blasting. Unlike harsh blasting for steel, aluminum-specific rooms prioritize precision: sensors monitor blasting duration to avoid over-treatment, while anti-static linings prevent metal dust accumulation. By combining gentle abrasion with automated controls, sandblast rooms for aluminum extrusions enable automotive manufacturers to achieve both functional cleanliness and aesthetic finishes, supporting the growing use of lightweight materials in vehicle design.
