Flap Disc Sourcing & OEM Project Support
OEM flap disc sourcing for Type 27 and Type 29 configurations in zirconia alumina, ceramic and aluminum oxide. Confirm backing, balance criteria, rated speed, sample plan and MOQ per quoted SKU.
Shanghai B2B Flap Disc Sourcing and OEM Support
SCOTTCHEN provides Shanghai-based B2B sourcing and OEM project support for Type 27 and Type 29 flap-disc inquiries. The responsible production source, abrasive cloth, backing, construction, rated speed and applicable documents must be identified for the exact quoted SKU rather than inferred from a general factory or history claim.
The quotation should state the abrasive-cloth source, flap count, backing, bond construction and agreed inspection plan. Material origin, bond integrity, balance, run-out and speed-related evidence are confirmed per SKU through supplier documents, representative samples and the written quality plan.
Buyers can compare standard- and high-density configurations under a common test plan. Cut rate, service life, vibration, finish and packaging requirements should be measured against the approved sample; MOQ, lead time, payment and Incoterms are confirmed in the written quotation or contract.
Flap Disc Types & Configurations
Type 27 (Depressed Center) Flap Discs
Type 27 flap discs use a relatively flat working face and are commonly evaluated for flat-surface grinding, weld blending and surface preparation. The exact hub, backing, diameter, arbor, grain, grit and rated speed must match the buyer's grinder, guard and approved SKU documents.
- Flat-profile application to validate
- Common RFQ diameters: 4.5", 5", 7"
- Common RFQ grits: P36, P40, P60, P80, P120
- Backing and arbor confirmed by SKU
Type 29 (Conical) Flap Discs
Type 29 flap discs use a conical working face that can be evaluated for edges, weld seams and contours. Angle, contact behavior, stock-removal rate, finish and safe operating conditions depend on the quoted construction and must be compared on representative samples.
- Conical-profile application to validate
- Weld, edge and contour test scenarios
- Common RFQ diameters: 4.5", 5", 7"
- Zirconia or ceramic options subject to quotation
Zirconia Alumina Flap Discs
Zirconia alumina configurations can be evaluated for steel, stainless steel and alloy grinding. Cloth source, flap count, backing, rated speed, cut rate, heat and service life vary by construction, so the approved choice should come from a controlled comparison against the buyer's workpiece and operating conditions.
- Zirconia material source confirmed in the quotation
- Sample testing can compare cut rate and service life
- Application suitability approved against buyer test conditions
- Density options confirmed by SKU
Ceramic Alumina Flap Discs
Ceramic alumina can be evaluated for stainless steel, high-alloy steel and higher-pressure grinding. Cut rate, heat, service life and cost depend on the abrasive cloth, disc construction, workpiece, tool and operating conditions, so comparative performance must be approved through representative sample testing rather than a fixed website percentage.
- Ceramic grain option quoted by SKU
- Heat and cut-rate targets defined in the RFQ
- Service life compared under buyer-approved test conditions
- Material and application scope confirmed in writing
Aluminum Oxide Flap Discs
Aluminum oxide configurations can be evaluated for general-purpose metal sanding, woodworking and lighter-duty applications. Price, cut rate, finish and service life depend on the cloth and disc construction; suitability and any cost advantage must be confirmed in the SKU quotation and sample test.
- Aluminum oxide option quoted by SKU
- Target workpiece recorded in the RFQ
- Density and backing confirmed in writing
- Common RFQ grits: P40 through P120
High-Density Jumbo Flap Discs
High-density flap-disc constructions use additional abrasive flaps and can be compared with standard-density discs for higher-volume grinding. Flap count, dimensions, grain, backing and expected service life must be defined for the quoted SKU and verified under the buyer's operating conditions.
- Flap count and density confirmed by SKU
- Service life verified by comparative sample test
- Application conditions recorded in the approval plan
- Zirconia or ceramic configurations subject to quotation

Applications
Why Choose Our Flap Discs
Documented Material Source
Abrasive-cloth brand, grade and country of origin are stated only when supported for the quoted SKU.
Backing Specification
Backing material, dimensions and construction are recorded in the approved specification.
Agreed Balance Criteria
Balance, run-out and sample acceptance methods are defined in the written quality plan.
Bond Evidence
Bond construction and any strength or speed-related test evidence are requested for the exact SKU.
Stainless Limits by SKU
Any Fe, S or Cl limit must be stated in the RFQ and supported by applicable evidence.
Private Label Scope
Custom labels, retail packaging, buyer-supplied barcode data and branded cartons are documented in the approved artwork.
OEM / Private Label Capabilities
SCOTTCHEN supports OEM flap-disc sourcing for distributors, welding suppliers, tool brands and industrial buyers. The written RFQ and quotation can compare grain, density, Type 27 or Type 29 profile, flap angle, backing and application requirements while naming the responsible production source.
Private-label scope can include shrink wrap, printed labels, color boxes, industrial cartons or blister packs. Applicable grit convention, maximum RPM, warnings, translations and buyer-supplied barcode data must be verified for the target market and recorded in the approved artwork; no FEPA, ANSI or marketplace acceptance is implied by this page.
If a project requires a nonstandard grain, backing or construction, the RFQ can ask identified sources to assess feasibility. Any formulation, engineering responsibility, setup cost, safety evidence, sample plan and production approval must be stated in the quotation; this page does not claim in-house formulation or development capability.
Frequently Asked Questions
Q1:What is the minimum order quantity for wholesale flap discs?
MOQ is quoted per diameter, profile, grit, grain, density, backing and packaging format. Ceramic materials, high-density constructions and printed packaging can have different setup quantities. Require the SKU-level quotation to identify all minimums and mixed-SKU assumptions.
Q2:What is the difference between Type 27 and Type 29 flap discs?
Type 27 presents a relatively flat working face, while Type 29 presents a conical face. Type 27 can be evaluated for flat blending and finishing; Type 29 can be evaluated for edges, weld seams and contours. Final selection requires the exact grinder, guard, angle, pressure, workpiece, rated speed and representative sample result.
Q3:Are your flap discs suitable for stainless steel?
Zirconia or ceramic configurations can be evaluated for stainless steel. State any iron, sulfur and chlorine limit in the RFQ and require material or test evidence for the exact quoted SKU. Final suitability, heat behavior and finish should be approved through representative sample testing.
Q4:What safety certifications do your flap discs meet?
The RFQ should state the target market, applicable safety standard, maximum RPM, grinder and guard compatibility, label requirements and evidence needed for the exact disc. Request report numbers, covered sizes and validity instead of relying on a general ISO, EN12413, MPA or oSa statement.
Q5:What is the production lead time for flap disc orders?
Lead time depends on the production source, abrasive cloth, construction, packaging, sample approval, inspection and quantity. Require dated material, sample, production, inspection and shipment milestones in the written quotation; this page does not promise a standard or rush schedule.
Q6:Can you supply flap discs under our private label brand?
Private-label scope can include printed labels, shrink wrap, color sleeves, cartons, blister packs and buyer-supplied UPC, EAN or FNSKU data. Safety text, translations and current retailer or marketplace requirements must be supplied and approved by the buyer; MOQ and print setup are confirmed in the quotation.
