Matte texture
Reduces reflectivity and creates a more uniform technical appearance across visible faces.
Surface Preparation
Bead Blasting for Custom Manufactured Parts
A media-blasting treatment used to create a controlled matte texture and prepare visible metal surfaces.
- Uniform matte texture
- Reduced machining marks
- Finish preparation
Finish overview
A consistent matte preparation that still needs cosmetic controls.
Bead blasting uses controlled media impact to soften machining marks and produce a matte or satin metal surface. It is often specified before clear or colored anodizing, or as a final visual treatment on selected stainless components.
The process does not erase deep tool marks, dents, scratches, or uneven geometry. Cosmetic faces, masking, media cleanliness, and handling after blasting should be defined to prevent contamination and inconsistent texture.
Appearance
What the finished surface can look and feel like.
Softened tool marks
Light machining patterns can become less prominent, but deep marks remain visible.
Edge-sensitive
Aggressive blasting can round fine detail or change the appearance of sharp edges.
Suitable processes
Manufacturing routes commonly paired with this finish.
Suitable materials
Base materials that require process-specific review.
Typical applications
Part families commonly reviewed for bead blasting.
Medical device housings
Sensor enclosures
Instrument panels
Anodizing pretreatment
Matte stainless brackets
Prototype appearance parts
Benefits
Where this option can add value.
- Creates a controlled non-reflective texture
- Reduces the visual prominence of light machining marks
- Prepares aluminum for a consistent anodized look
- Supports a clean industrial appearance without paint
Limitations
Requirements that need engineering review.
- It cannot repair dents, deep scratches, or poor base finishing.
- Threads, sealing faces, labels, and precision fits may need masking.
- Media contamination can affect stainless surfaces.
- Texture varies with geometry and nozzle access.

FAQ
Bead Blasting questions from engineering and sourcing teams.
Does bead blasting remove CNC tool marks?
It can reduce the visibility of light marks, but it does not remove deep grooves, dents, or poor blending. Base machining quality remains important.
Can bead blasting be used before anodizing?
Yes. It is commonly used to create a matte base texture before anodizing. The blasted surface and final anodized sample should be approved together.
Should threaded holes be protected during blasting?
Critical threads, sealing faces, markings, and fitted areas often need masking or controlled cleaning. Identify them on the drawing.
