Abrasive Flow Machine Uses Diamond Fine Powder,Silicon Carbide Powder or other Abrasives Mixed Into Polymer Elastic as a soft medium.The abrasives flow up and down through the inner holesor over the machined surface to achieve surface polishing.Especially suitable for all kinds of mould and irregular shape tiny cavities.The automotive industry is increasingly adopting Abrasive Flow Machining (AFM) due to its unique advantages in precision,efficiency,and versatility,particularly as vehicle technologies advance. Here’s why AFM is becoming a go-to solution: 
1. Superior Finishing for Complex Parts  
AFM excels at polishing intricate internal geometries—such as fuel injector nozzles,turbocharger housings,and transmission components—where traditional methods (e.g.,grinding,honing) struggle. It ensures consistent surface finishes (Ra < 0.1 µm) critical for performance and durability.  
2. Burr-Free & Stress-Free Results  
Unlike mechanical deburring,AFM eliminates microburrs and subsurface damage,reducing part failure risks.This is vital for EV battery cooling channels and high-pressure fuel systems,where even minor imperfections can cause leaks or inefficiencies.  
3. Cost & Time Savings  
AFM automates finishing for high-volume production,reducing labor costs and cycle times. For example,it can polish multiple fuel injectors simultaneously,unlike manual methods.  
4. Compliance with Tight Tolerances  
As emissions regulations tighten,AFM helps meet strict flow efficiency standards (e.g.,in diesel injectors) by ensuring smooth,uniform surfaces.  
5. Future-Proofing for EVs & Lightweighting  
AFM is ideal for aluminum and 3D-printed components,supporting lightweight designs without compromising surface integrity.Conclusion:AFM’s precision,scalability,and adaptability make it indispensable for next-gen automotive manufacturing.
