Precision Sandblasting & Bead Blasting Solutions
Sandblasting (often referred to as Bead Blasting) is an essential surface finishing process used to clean, texturize, and prepare parts for final coating. By propelling a stream of abrasive media at high velocity against the workpiece, we can remove CNC machining tool marks, burrs, and heat-treat scales, leaving behind a uniform, non-directional matte finish.
At JUCHENG, we treat blasting as a precision operation, not just a cleaning step. We utilize automated tumbling blasters for batch consistency and manual cabinets for delicate features. Whether you require a satin-smooth finish on an aluminum housing before anodizing or a rougher texture on steel for paint adhesion, our technicians precisely control air pressure, media type, and dwell time to achieve the exact surface roughness (Ra) specified in your design.
Sandblasting

JUCHENG’s Surface Texturing Capabilities

We tailor the blasting process to suit the material and desired aesthetic:
  • Media Variety: We stock multiple media types, including Glass Beads (for cleaning and satin finishes), Aluminum Oxide (for aggressive etching and matte finishes), and Ceramic Grit (for tough metals).
  • Roughness Control: We can target specific Ra values (e.g., Ra 1.6µm or Ra 3.2µm) by adjusting particle size (Mesh #80 to #220) and blasting pressure.
  • Precision Masking: Sandblasting is abrasive. We expertly mask critical features like bearing bores, sealing surfaces, and threads to ensure they remain untouched and within tolerance.
  • Large Part Capacity: Our walk-in blasting rooms accommodate large frames and chassis, while automated cabinets handle small precision parts.

Materials Available

Suitable Materials for Blasting
Almost any solid material can be blasted, but the results vary:
Material Recommended Media Resulting Finish
Aluminum Glass Beads (#120) Satin silver, smooth feel. Hides tool marks best.
Stainless Steel Glass Beads / Ceramic Uniform matte grey. Removes heat tint from welding.
Carbon Steel Aluminum Oxide Rough texture. Ideal for removing rust and preparing for powder coat.
Titanium Fine Ceramic Satin finish. Removes alpha case.
Plastic (PC/Acrylic) Fine Glass Beads "Frosted" glass look. Used for light diffusion.
Brass/Copper Glass Beads Matte gold/bronze finish. Removes tarnish.

Comparison

Comparison: Glass Bead vs. Aluminum Oxide Blasting
Choosing the right media is critical for the final look.
Feature Glass Bead Blasting Aluminum Oxide Blasting
Shape Spherical (Round) Angular (Sharp)
Action Peening / Polishing Cutting / Etching
Finish Satin / Semi-Bright Matte / Dull
Surface Roughness Lower (Smoother) Higher (Rougher)
Material Removal Minimal Moderate
Best For Cosmetic parts, cleaning Paint prep, rust removal

Why Choose Us

  • Consistency: We regularly replace blasting media to prevent contamination and ensure "fresh" sharp edges, avoiding the muddy look caused by broken-down media.
  • No Dimensional Change: We carefully control pressure on precision parts to avoid altering critical dimensions or warping thin walls.
  • Cleanliness: All blasted parts undergo ultrasonic cleaning to remove residual dust and media trapped in blind holes before shipping or plating.
  • Visual Standards: We use visual comparators to ensure the texture matches the approved sample across batch production.

Advantages

  •  Hides Imperfections: Effectively blends minor tool marks, scratches, and cutter paths into a uniform texture.
  • Improves Adhesion: Increases surface area for better bonding of paints, glues, and powder coatings.
  • Deburring: Light blasting removes loose burrs from machined edges.
  • Aesthetics: Creates a modern, high-end matte look that is non-reflective and anti-glare. 

Industries Served

  • Consumer Electronics: Laptop bodies, camera housings (Satin finish).
  • Medical: Surgical instruments (Non-glare finish for operating rooms).
  • Automotive: Engine components, suspension parts (Cleaning & Prep).
  • Aerospace: Structural brackets, turbine blades (Peening for strength).
  • Architecture: Door handles, signage, decorative panels.
