Application fit

When to Specify Bead Blasting for Custom Parts

Specify bead blasting when you need a clean, non-directional matte finish, light deburring, coating pretreatment or a controlled texture that keeps dimensions stable.

  • Need a uniform satin or matte appearance without visible directional scratches.
  • Need pre-treatment before anodizing, plating, painting or powder coating.
  • Need to remove light burrs, surface contamination or machining marks.
  • Need low-impact finishing for thin-wall, delicate or complex geometry.
  • Need sample approval, roughness control and batch traceability for production release.

Compatible Materials, Blasting Media and Finish Notes

Bead blasting results depend on media hardness, part substrate, wall thickness, masking plan and target surface roughness. SinoCMI checks these factors before recommending the best blast route.

Main Blasting Media

  • Glass bead for standard satin and matte finishing, gentle cleaning and mild peening
  • Ceramic bead for heavy-duty deburr and long service life in high-volume runs
  • Soft plastic media for delicate components and lower-impact surface treatment

Compatible Base Materials

  • Metals: aluminum alloy, stainless steel, titanium, superalloy, brass and carbon steel
  • Non-metals: engineering plastics, composites, 3D printed parts and optical components
  • Thin-wall or delicate parts can be reviewed with media size, pressure and masking controls

Drawing and Finish Notes

  • Specify matte, satin or low-glare appearance, target roughness and protected areas
  • Call out pre-anodizing, pre-plating, passivation or assembly-prep needs early in RFQ
  • Include sample approval, dimensional control and batch documentation requirements

Surface Finish Characteristics and Quality Documentation

Quality depends on the chosen media, pressure, nozzle angle and cleaning controls. SinoCMI pairs finish targets with inspection checkpoints so the blast result matches the drawing and next process step.

Requirement SinoCMI Support Buyer Value
Appearance Moves parts from shiny or tool-marked to a uniform low-glare satin or matte finish Improves visual consistency and reduces directional scratches
