Bead Blasting Overview
Bead blasting propels fine spherical media against a part surface using compressed air. It removes burrs, machining marks, and minor surface imperfections. The result is a uniform matte or satin texture. It is a surface finish process, not a material-removal process. Part dimensions stay intact.
- Produces a clean, non-directional surface
- Improves coating adhesion for anodizing, powder coating, and paint
- Media type and pressure are selected based on your finish requirements
At Yijin Solution, masking, media selection, and surface prep are confirmed during the DFM review before machining begins.
Sheet metal fabrication is one stage in a larger product development process. We support the full path from initial concept through engineering review, prototyping, design validation, and volume production.

Media and Finish Options
We offer two media types for bead blasting. The choice depends on your material, target finish, and downstream coating requirements.
- Glass bead is the standard media for most cosmetic finishes. Glass beads produce a smooth, uniform matte on aluminum and stainless steel without embedding particles or altering the base material. This is the default choice for parts going to anodizing or powder coating.
- Sand is a more aggressive media that removes heavier surface contamination, scale, and old coatings. Sand media produces a coarser matte texture and is suited to parts that need thorough surface preparation before painting or protective coatings. It works well on carbon steel and raw castings.
Materials We Bead Blast
We bead blast parts across the following material families. Each responds differently to media impact, so we adjust pressure and media selection per material.
If you are unsure which media suits your material, specify the desired finish texture and coating requirement in your quote request. Our engineering team will recommend the media and parameters during the DFM review.
Aluminium-Legierungen
Produce a uniform matte appearance with no directional lines. Bead blasting aluminum creates an ideal pre-anodizing surface. Glass bead is the recommended media for 6061, 7075, and 5052 alloys.
Rostfreier Stahl
Takes a consistent satin finish that removes machining marks without compromising corrosion resistance. Glass bead at moderate pressure produces a clean, non-directional surface on 304 and 316 stainless.
Kohlenstoffstahl
Benefits from deburring and surface cleaning before powder coating or painting. Sand media is often the better choice for carbon steel parts with mill scale or weld discoloration.
Messing
Takes a decorative matte finish without aggressive material removal. Glass bead at lower pressure preserves the warm tone of the brass surface while eliminating handling marks.
Kupfer
Takes a soft matte finish that highlights the natural color. Suitable for decorative and architectural parts where a subdued, even texture is preferred over a polished or mirror surface.
Titan
Takes a uniform matte texture that removes machining marks and prepares the surface for anodizing or Physical Vapor Deposition (PVD) coating. Glass bead is recommended to avoid embedding ferrous contaminants in the titanium surface.
Our Bead Blasting Process
Every bead blasting order follows the same six-step workflow, from quote to shipment.
- Quote and DFM review. Share your Computer-Aided Design (CAD) files and specify the target finish. Our engineering team reviews the design for masking requirements, media compatibility, and any features that need protection during blasting.
- Part preparation and masking. We mask critical surfaces, threaded features, tight-tolerance bores, and any areas where the matte texture is not desired. Masking is planned at the DFM stage, not after machining.
- Media selection. We select glass bead or sand based on your material, the required finish texture, and whether the part will receive downstream coating. Media selection is documented on the process routing sheet.
- Blasting. Parts are blasted in a controlled cabinet at calibrated pressure. The operator works the nozzle at a consistent distance and angle to produce an even finish across all exposed surfaces.
- Post-blast cleaning and inspection. After blasting, we remove masking, blow off residual media, and inspect the part for finish uniformity. For parts requiring dimensional verification after finishing, Zeiss Coordinate Measuring Machine (CMM) inspection is available.
- Packaging and shipment. Finished parts are packaged to prevent surface damage in transit. We ship from our Shenzhen facility or our Florida location for North American customers.

SPEZIFIKATION
Eloxieren
Anodizing builds a hard oxide layer on aluminum surfaces. It improves corrosion resistance and allows color dyeing without paint. Available in Type II and Type III hard anodize up to 50 ΞΌm thickness.
Pulverbeschichtung
Electrostatic powder coating delivers a durable, even finish in any RAL color. Coating thickness ranges from 60 to 120 ΞΌm. It resists chipping, scratching, and UV fading better than wet paint.
Beschichtung
BΓΌrsten
Mechanical brushing creates a uniform satin grain on stainless steel and aluminum. It removes surface imperfections and produces a professional, non-reflective appearance.
Polieren
Multi-stage polishing achieves mirror finishes down to Ra 0.05 ΞΌm. Common on stainless steel parts for medical, food processing, and optical applications.

Why WΓ€hlen Sie Yijin Solution for Bead Blasting
We control the bead blasting workflow from DFM review through surface inspection and shipment. That integrated approach means consistent finish quality, accurate masking, and a quality system that meets aerospace, medical, and automotive certification requirements.
Every bead blasted order is inspected for finish uniformity before shipment. For parts with tight tolerances, Zeiss Coordinate Measuring Machine (CMM) verification is available post-blast. ISO 9001, AS9100D, ISO 13485, and IATF 16949 certifications are held across our quality system.
Bead blasting is scheduled into the production run at the quote stage. Parts move from machining to surface prep to blast cabinet to inspection in one continuous workflow, keeping lead times for prototype and production orders on track.
We bead blast single prototypes and production runs of 10,000+ parts through the same controlled process and quality system. There is no minimum order quantity, and volume does not change the inspection standard.
Prototype and production parts are bead blasted in the same facility using the same media, pressure settings, and process controls. The finish specification validated on your first sample applies directly to your production run.
We bead blast aluminum, stainless steel, carbon steel, brass, copper, and titanium, with media type and pressure adjusted per material. Glass bead suits most cosmetic and pre-coating applications. Sand media handles heavier surface preparation on carbon steel and castings.
Running bead blasting in-house alongside machining and fabrication removes the logistics cost of a separate finishing vendor. Our DFM review confirms masking and media requirements at the quote stage, so parts are processed correctly from the first run.

FAQs on Bead Blasting Services
Common questions about media selection, tolerances, lead times, and service scope are answered below.
Will bead blasting affect part tolerances?
Bead blasting removes minimal material from the part surface. It is a cosmetic process, not a material-removal process. For parts with tight tolerances, we mask critical dimensions and features during blasting to ensure they remain within specification.
Which bead media do you recommend for aluminum versus stainless steel?
Glass bead is the recommended media for both aluminum and stainless steel. It produces a clean, uniform matte without embedding particles or altering the base metal. For aluminum parts going to anodizing, glass bead provides the ideal surface texture for even oxide layer formation.
Can you mask specific surfaces or threaded features during blasting?
Yes. We routinely mask threaded holes, bearing surfaces, precision bores, sealing faces, and any area where the matte texture is not wanted. Masking is planned during the DFM review so it is documented before production starts.
What is the typical lead time for bead blasting on machined parts?
For prototyping orders, the combined machining and bead blasting lead time is 7 to 10 days. Production orders typically ship in 10 to 15 days. Lead times depend on part complexity, batch size, and whether other finishing steps are included.
Do you offer bead blasting as a standalone service, or only with machining and fabrication orders?
Bead blasting is an add-on surface finishing service. Customers select it as part of their CNC machining, sheet metal fabrication, die casting, or 3D printing order. It is not offered as a standalone service for parts manufactured elsewhere.
What is the difference between glass bead blasting and sand blasting?
Glass bead media produces a smoother, finer matte finish and is gentler on the base material. It is the preferred choice for cosmetic surfaces and pre-coating preparation on aluminum and stainless steel. Sand is more aggressive and removes heavier contamination, scale, and old coatings. It is better suited for carbon steel parts or castings that need thorough surface cleaning before painting.
