Bead Blasting Services
Define a matte finish your team can accept.
Plan a consistent blasted appearance for machined or fabricated parts. Identify cosmetic faces, protected interfaces and the next finishing operation so media, texture and cleaning can be reviewed together.

Visible housings, covers and machined components where a diffuse surface texture is appropriate.
Cosmetic blasting is not automatically a qualified shot-peening process, a deburring solution or a corrosion-protection system.
What this process does
Bead blasting propels selected bead media at a surface to clean or modify its texture. The result depends on media, substrate and process conditions; a matte appearance does not establish a particular roughness value.
Choose the route from your requirements.
Use these points to prepare an enquiry. The selected process, material compatibility and acceptance criteria should be confirmed for your drawing.
On smaller screens, scroll the table horizontally.
| Your requirement | What to specify | What to review |
|---|---|---|
| Cosmetic texture | Provide a sample and identify viewing faces. | Agree visual acceptance independently of measured roughness. |
| Precision interfaces | Mark seal lands, bores, threads and datums. | Review masking and edge protection. |
| Stainless and contamination-sensitive work | Identify cleanliness and cross-contamination requirements. | Confirm media selection and handling route. |
| Following finish | State anodizing, painting or other subsequent processing. | Agree the sequence and surface preparation needed. |

Protect the features that make the part work.
Mark the surfaces that carry function, fit and appearance. A clear drawing helps separate essential requirements from unnecessary processing.
Media access
Deep recesses and small passages may be difficult to process or clean. Identify internal areas and trapped-media risks.
Underlying defects
Blasting changes texture but may not remove deep tool marks or scratches. Review the incoming condition and any prior blending needed.
Sample consistency
The same media label can produce different results on different materials. Use a representative material and geometry for sample approval.
Agree the evidence before production.
Inspection should answer the requirements on your order. Define the method and acceptance criteria when a characteristic is important to the application.
- Media and process route agreed
- Sample appearance checked on specified faces
- Masked features and edge condition inspected
- Residual media and cleanliness requirements checked
Testing and documentation are confirmed in the quotation. A finish name or reference image does not establish certification, performance or compliance.
From drawing to an agreed finish.
Send the part context
Share the drawing, material, quantity and operating environment. Identify cosmetic and functional surfaces.
Review the process
Resolve preparation, access, masking and the sequence with machining or other finishing operations.
Confirm acceptance
Agree samples, measurements and documentation. Record the approved drawing revision and open requirements.
Release the order
Confirm the quoted route, schedule and packing requirements before work starts.
Does bead blasting guarantee a specific Ra?
No. Specify Ra or another parameter with a measurement method if it matters. A visual matte sample and a numerical roughness requirement are separate acceptance criteria.
What should I send for a quotation?
Send the drawing revision, material grade, quantity and base material and starting surface condition, cosmetic faces and sample reference. Mark the required surfaces and any acceptance tests. Include your target date and shipping destination.
Can I send parts that are already manufactured?
State that the parts are customer-supplied and include their current condition, existing coatings and dimensions. Acceptance, incoming inspection and the finishing route need confirmation before shipment.
Can you provide a specific inspection report?
List the required characteristics, test methods, sample quantity and report format with the enquiry. The quotation should confirm the agreed inspection scope; additional tests are not implied by the service name.
What affects price and lead time?
Part size, quantity, incoming condition, preparation, masking, finish requirements and inspection scope all affect the route. Share the complete specification so cost and schedule can be confirmed for the order.
