Professional Surface Preparation and Finishing for Metal and Plastic Components
GCNOV provides professional Sandblasting services for CNC machined parts, sheet metal components, castings, weldments, molds, tooling, additive manufacturing parts, and industrial equipment. Sandblasting is an effective surface treatment process used to clean, texture, deburr, remove contaminants, and prepare surfaces for painting, powder coating, anodizing, plating, and other finishing operations.
Sandblasted surfaces offer a uniform matte appearance, improved coating adhesion, and enhanced surface quality for both functional and decorative applications.
GCNOV supports prototype, low-volume, and production manufacturing projects with a wide range of blasting media and surface finish options.
What is Sandblasting?
Sandblasting, also known as Abrasive Blasting, is a surface treatment process that propels abrasive media at high speed against a component surface to remove contaminants, create surface texture, and improve finish quality.
The process can be used for:
- Surface cleaning
- Oxide removal
- Rust removal
- Paint stripping
- Deburring
- Surface texturing
- Coating preparation
- Cosmetic finishing
Sandblasting is commonly performed before anodizing, powder coating, painting, plating, and other secondary finishing processes.
Benefits of Sandblasting
Uniform Surface Finish
Creates a consistent matte or textured appearance across the entire component.
Improved Coating Adhesion
Enhances bonding performance for paints, powder coatings, anodizing, and plating.
Removes Surface Contaminants
Effectively removes rust, oxidation, scale, oil residues, and old coatings.
Deburring Capability
Helps remove minor burrs and sharp edges created during manufacturing.
Cosmetic Enhancement
Produces attractive, professional-looking surfaces.
Versatile Processing
Suitable for metals, plastics, composites, and additive manufacturing parts.
