Sandblasting Service
Sandblasting Service is a surface treatment technology that uses high-speed abrasives to impact metal surfaces, effectively removing rust, oxide scale, old paint, and contaminants. This process cleans the workpiece and provides a uniform roughness, significantly enhancing adhesion for subsequent painting, plating, or bonding.
This service is a critical pre-treatment for all coating and surface finishing processes. It ensures that coatings (such as baking paint or electroplating) bond perfectly with the substrate, extending workpiece lifespan and improving final product quality. As the first step in integrated processing, it provides the cleanest and most suitable surface for subsequent procedures.
➤ Suitable Materials
▪️ Hot Rolled Steel (SPHC) / Structural Members: Most commonly used to remove rust and mill scale (black skin), restoring the metal's natural color; ideal pre-treatment for structural painting.
▪️ Cold Rolled Steel (SPCC): Cleans surface oil and light rust, providing a uniform rough surface for better paint adhesion.
▪️ Stainless Steel (SUS) / Aluminum: Glass beads or fine abrasives can be used for atomization, achieving a non-reflective, high-quality matte finish.
▪️ Castings & Molds: Effectively removes burrs after demolding, carbon deposits, and oxidation layers from heat treatment.
➤ Service Features
▪️ Thorough Surface Cleaning: Quickly removes stubborn rust, thick oxide layers, and old paint, saving manual rust removal time.
▪️ Enhanced Coating Adhesion: Uniformly roughens the surface (increasing surface area), ensuring paint and plating layers grip firmly and do not peel easily.
▪️ Maintains Precision: As a surface treatment, it does not affect the workpiece's dimensions, thickness, or structure.
▪️ Diverse Aesthetic Finishes: Different abrasives (like glass beads) can be selected to create matte, satin, and other visual textures.
▪️ Optimal Pre-Processing: An essential step before powder coating, fluorocarbon painting, or electroplating, ensuring post-process quality.
➤ Applications
▪️ Steel Structures & Machinery: Rust removal and cleaning for H-beams, channels, steel plates, and machine bases.
▪️ Pre-Painting Treatment: Base preparation for sheet metal parts and enclosures before powder or liquid coating.
▪️ Renovation & Refurbishing: Paint stripping and refurbishing for molds, old equipment parts, and automotive components.
▪️ Decorative Frosting: Matte finishing for stainless steel or aluminum parts to enhance visual quality.
