Bead Blasting Overview

CustomParts-MFG delivers professional controlled bead blasting surface finishing complying with Nadcap, ASTM and REACH/RoHS standards, certified ISO9001, IATF16949 & ISO14001. Our automated & manual blast lines adopt spherical glass/ceramic bead media to generate uniform non-directional matte/satin texture with less than 5μm material removal, ideal for precision deburring, surface cleaning, fatigue peening and pre-anodizing/plating pretreatment. Fully integrated with in-house CNC machining and subsequent coating processes, bead blasting solutions serve aerospace, medical, automotive, semiconductor and industrial equipment fields globally.

Your bead blasted parts provide outstanding consistency and a superior finish, which significantly enhances the quality of our final assemblies.

Core Functional Advantages of Precision Bead Blasting

  • Uniform Non-Directional Matte Finish: Eliminates machining tool marks & directional scratches to form consistent random micro-texture without surface embedment.
  • Minimal Dimensional Variation: Only ≤0.0002”(5μm) controlled material loss, perfectly retain tight dimensional tolerances for precision components.
  • Excellent Coating Adhesion Base: Micro cratered surface greatly boosts bonding performance for anodizing, plating and powder coating to avoid peeling/blistering.
  • Improved Component Fatigue Resistance: Gentle cold peening effect closes surface micro-cracks and extends part service life under cyclic load.
  • Wide Material Adaptability: Adjustable blast pressure & media size prevents substrate deformation on thin-wall and delicate parts.

Available Blasting Media & Applicable Base Materials

Available Blasting Media & Applicable Base Materials

Main Spherical Blasting Media

  • Glass Bead: Most mainstream option for standard satin/matte finishing, general cleaning and mild peening;
  • Ceramic Bead: High hardness for heavy-duty deburr and long service life in high-volume production;
  • Special Plastic Media: Low-impact formula for soft engineering plastic & delicate component surface treatment.

Compatible Workpiece Substrates

  • Metals: Aluminum alloy, stainless steel, titanium, superalloy, brass & carbon steel;
  • Non-Metal: Engineering plastics, composite material, 3D printed parts and optical components

Bead Blasting Surface Finish Characteristics

Bead Blasting Surface Finish Characteristics

Bead blasting alters two key surface attributes of precision parts:

  • Appearance: Transitions from as-machined shiny or tool-marked to a uniform, low-glare satin or matte finish.
  • Texture: Eliminates directional scratches. Creates a random, crater-free micro-texture that improves lubricant retention and adhesive bonding.
  • Dimensional Impact: Properly executed bead blasting removes less than 0.0002" (5 microns) of material, preserving tight tolerances.
  • Stress Relief: Light peening action closes micro-cracks and improves fatigue resistance.

Bead Blasting Secondary Processing Integration

Bead blasting is never an isolated step in our one-stop service. It integrates with:

  • CNC Machining (Milling/Turning): Applied after deburring but before critical dimension inspection.
  • Anodizing: Creates an ideal anchor pattern for Type II or Type III hard anodize, preventing peel-off.
  • Plating (Nickel, Zinc, Silver): Improves adhesion and eliminates blistering.
  • Passivation: Bead blasting followed by passivation removes free iron from stainless steel surfaces.
  • Laser Marking: Provides a consistent background for high-contrast laser marking.
  • Assembly Prep: Cleans mating surfaces for press-fit or adhesive-bonded assemblies.

FAQs About Bead Blasting

What is Bead Blasting?

expand_less expand_more

A: Precision surface finishing using spherical glass/ceramic beads under controlled air pressure for cleaning, deburr, matte texturing and pre-coating preparation without heavy material removal.

What blasting media options do you supply?

expand_less expand_more

A: Glass bead, ceramic bead and soft plastic bead; media specification customized according to workpiece hardness and required Ra.

Difference between bead blasting and conventional sandblasting?

expand_less expand_more

A: Bead blast uses round spherical media for smooth uniform satin finish; sandblast adopts sharp angular abrasive for aggressive deep etching & heavy rust removal.

Can bead blast serve as pre-treatment before anodizing/plating?

expand_less expand_more

A: Yes, it forms ideal anchor texture to drastically improve coating adhesion and effectively eliminate blister defect.

Pre-treatment requirement before bead blasting?

expand_less expand_more

A: Complete degreasing to wipe out surface oil; thick oxide & heavy coating must be stripped in advance for uniform blasting effect.

Can bead blasting be used as a final finish before anodizing or plating?

expand_less expand_more

A: Yes, it is an excellent preparatory finish. The uniform, matte surface creates an ideal anchor profile for superior adhesion of subsequent anodizing, plating, painting, or powder coating layers.
