Product Positioning

Hybrid Flap Discs Combining Cutting and Conditioning

Interleaved flap discs are positioned as surface-quality-driven hybrid discs for angle grinders. By alternating coated abrasive cloth flaps with nonwoven conditioning flaps, they combine material removal + scratch blending + surface texturing in one tool.
They are ideal for parts requiring consistent appearance and scratch patterns (e.g., stainless steel, aluminum, decorative components), for weld blending, surface blending, and light deburring.

Processing Logic

Nonwoven Buffering Makes Cutting Results More Controllable

Standard flap discs may gouge or create deep scratches under high pressure or unstable angles. Interleaved discs use nonwoven buffering to:

• Reduce peak cutting aggressiveness and gouging risk;
• Turn scratches from “deep and random” into “shallow and uniform”;
• Improve weld blending and cosmetic surface finishing.

Backing Structure & Performance Limits

Surface-Oriented, Not a Heavy Grinding Disc

• Strengths: more uniform finish, lower heat, smoother blending
• Limits: not for heavy stock removal or high-impact grinding; for heavy removal choose metal/fiberglass flap discs or grinding wheels
• More forgiving on stainless, but still requires controlled angle and pressure

Machine Compatibility & Operating Conditions

Angle Grinder Surface Conditioning Setup

• Machines: angle grinders (electric/pneumatic)
• Recommended conditions: medium to low pressure, stable working angle, continuous movement
• Goal: appearance and scratch consistency over maximum removal rate

Typical Applications & Industries

Stainless & Cosmetic Finishing Workflows

• Stainless weld blending and surface blending
• Light deburring and cosmetic finishing for aluminum parts
• Edge radiusing and brushed-finish transitions for sheet metal
• Cosmetic components: enclosures, handrails, kitchen & bathroom hardware

 

—————————————————————————————————————————————————————————————————————————————————————————-

Grit Range & Recommended Use

Typical Grit/Grade Strategy for Blending

Typical recommendation

• P40–P60: light removal + weld blending (productivity focus)
• P80: general surface blending (most common)
• P120–P150: cosmetic refinement and texture smoothing

OEM & ODM Capability

Texture-Driven Customization

OEM/ODM supported: interleaving ratio (cloth/nonwoven), nonwoven density/grade, abrasive system, diameter/arbor/thread standards, Type 27/29, and private label/packaging—engineered for target textures and materials.

Why Choose Us

Consistent Appearance Requires Controlled Structure

Consistent cosmetic results require structural control: nonwoven density, layup angle, and bonding system drive scratch pattern, heat behavior, and disc life. We engineer for batch stability to make cosmetic finishing repeatable.

Usage & Storage Recommendations

Finish Consistency Depends on Angle, Pressure and Movement

• Use medium to low pressure with a stable angle; avoid dwelling
• For stainless cosmetic parts, step through grits to reduce rework
• Store dry and shaded; moisture can affect nonwoven performance
• Reseal after opening to keep discs clean and dry
