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.

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.

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. |
| Acero Inoxidable | 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. |
| Titanio | 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. |

Por qué elegirnos
- 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).
- Automotriz: Engine components, suspension parts (Cleaning & Prep).
- Aerospace: Structural brackets, turbine blades (Peening for strength).
- Architecture: Door handles, signage, decorative panels.
