Here are some of MPI finishing processes:

• Cleaning: Removing dirt, debris, or other unwanted materials 
• Etching: Using chemicals to create a design or message on the surface 
• Coating: Applying a layer of material to the surface, such as paint, powder coating, or electrocoating 
• Engraving: Using a laser or CNC to create a design or message on the surface 
• Polishing: Smoothing the surface of a part 
• Sand blasting: Using sand or other abrasive materials to remove material from the surface 
• Electroplating: Passing an electric current through dissolved metal ions to adhere to the surface 
• Hot blackening: Applying a thin layer of black oxide to the surface to increase abrasion resistance

Why is finishing important?

• Appearance: Finishing can enhance the visual appeal of a part. 
• Durability: Finishing can make a part more durable and resistant to corrosion, wear, and tarnishing. 
• Function: Finishing can improve a part’s function by making it easier to bond with other parts or by removing elements that might cause issues.
