Product Description
I. Product Definition and Composition
Core Composition: Made with flexible sponge as the base material, embedded with abrasive particles such as diamond sand and aluminum oxide, and compounded through adhesive bonding and flocking processes.
Alias System: Also known as sponge sanding blocks, polishing blocks, resin grinding blocks, and plastic grinding blocks, depending on the shape and application.
II. Manufacturing Process
Base Material Processing: The sponge is cut and shaped to ensure uniform porosity.
Abrasive Compounding: Abrasive particles are fixed onto the sponge surface using adhesive bonding or electrostatic flocking technology.
Post-Processing: Custom shapes (square, round, irregular) are cut using molds, and some products undergo hydrophobic or corrosion-resistant coating treatments.
III. Core Performance Advantages
Flexibility:High elasticity sponge base conforms to curved surfaces (e.g., automotive bodywork, carved furniture) for seamless grinding.
Versatility:Water-absorbent structure supports long-term wet grinding (reduces dust) and regains elasticity when dry, allowing for repeated washing and reuse.
Durability:Special treatment versions can withstand weak acids/alkaline cleaning agents and are suitable for corrosive environments like metal rust removal.
Customization:Available in multiple grit sizes (20-400 mesh), with dimensions from ranging hand-sized blocks to industrial rolls, suitable for both manual fine grinding and mechanical operations.
IV. Typical Applications
Home Manufacturing:
-
Precision grinding of curved surfaces on solid wood furniture and paint surface transition treatment.
-
Polishing of complex patterns on decorative crafts.
Industrial Manufacturing:
-
Smoothing of stainless steel welds (wet grinding to prevent overheating).
-
Removal of parting lines on injection-molded parts.
Automotive Repair:
-
Smoothing of interfaces in localized repainted areas.
-
Cleaning of wheel hub oxidation layers.
Special Materials Processing:
-
Beveling of acrylic/glass edges (wet grinding with coolant to prevent chipping).
-
Surface finishing of composite materials (carbon fiber).
V. Selection and Technical Considerations
Grit Matching:
-
Coarse grinding (80-120 mesh)
-
Fine grinding (150-240 mesh)
-
Superfine polishing (300 mesh+)
Base Material Hardness:
-
Soft (suitable for paint surfaces)
-
Hard (for metal rust removal)
Process Compatibility:
-
When using with power tools, select the reinforced adhesive type to prevent detachment at high speeds.
