From Drawing or Sample to Production-Ready Parts
Develop speaker surrounds, passive-radiator diaphragms, gaskets and molded rubber parts through our source-factory network — with tooling, material, geometry and approval criteria made clear before bulk production.
Drawing or sample based
Existing or new tooling
Physical sample approval
Export coordination
A practical starting point
You do not need a finished specification to begin
Start with the best information you already have. We use it to identify missing decisions before tooling or sampling begins.
I have a physical sample
We can review geometry, material clues and tooling options. The final production specification still requires approval.
I have a performance target
Share the driver, application, excursion, environment and target response so the part can be specified from use.
Customization scope
Define the part around the application
Nominal inches are only a starting label. A production-ready part connects geometry, material, function and approval criteria.
Dimensions & Roll Profile
Outer and inner diameter, roll width, height, thickness and mounting geometry.
Material & Hardness
IIR, EPDM, NBR, SBR, foam or a project-specific compound and Shore hardness.
Tooling
Existing-tool matching, tooling modification review or new compression mold development.
Functional Target
Compliance, excursion, sealing, weather exposure or F0 requirements defined by application.
Appearance
Color, surface finish, trimming standard and visible-part requirements.
Packaging & Identification
Bulk export packing, labels, carton marks and project-specific part identification.
RFQ checklist
Send enough information for a useful answer
A complete RFQ reduces assumption-driven quotes and makes tooling, sample cost and lead-time discussions more reliable.
- Drawing, CAD profile or clear photos of the physical sample
- Critical dimensions and tolerances — not only the nominal driver size
- Application: indoor, automotive, marine, outdoor or industrial
- Material preference, target hardness or an approved reference part
- Estimated sample quantity, order quantity and annual demand
- Functional checks, compliance documents and packaging requirements
- Destination country and target delivery date
Development process
Five approval gates before repeat production
Each stage should close a specific sourcing risk before the next commitment is made.
- 01
Technical Review
We review your drawing, physical sample, application, critical dimensions and target quantity.
- 02
Tooling & Quote Plan
We check existing tooling first, then quote new tooling only when the approved geometry requires it.
- 03
Sample Development
Material, hardness and molding settings are developed into a physical sample for measurement and fit checks.
- 04
Approval Freeze
The approved drawing, material, profile, finish and sample become the baseline for repeat production.
- 05
Production & Inspection
Bulk production follows the approved baseline with agreed in-process and pre-shipment checks.
Approval & quality control
Approve the baseline, then inspect against it
A factory photograph is evidence of equipment, not a specification. The drawing, approved sample and agreed inspection plan define what repeat production must match.
Geometry
Profile and critical dimensions can be checked by gauges, calipers or 2D optical measurement.
Material
Hardness, tensile or cure-related checks are selected according to the approved requirement.
Function
F0, environmental ageing or application-specific testing is agreed when the project needs it.
Appearance
Molding, trimming, surface, contamination and packing criteria are confirmed before shipment.
Material families
Material is selected from the application and approved result — not from the material name alone.
IIRDamping & air sealing
EPDMWeather, ozone & UV exposure
NBROil and heat exposure
SBRBalanced performance & cost
FoamLow mass & high sensitivity
CustomApplication-specific formulation
Commercial expectations
Timing and MOQ become reliable only after the production route is known.
- Feasibility review
- Initial response normally within one business day when the RFQ information is complete.
- Sampling
- Existing-tool samples can be faster; new tooling and compound development receive a project schedule.
- MOQ
- Depends on material, tooling, part size, finishing and whether the order uses an existing production route.
- Production
- Bulk timing starts after sample approval, commercial confirmation and any required material preparation.
Frequently Asked Questions
What speaker components do you manufacture?
As an OEM/ODM manufacturer of speaker components we make the full driver-parts line: rubber edge surrounds, foam surrounds, speaker gaskets, paper cones and custom cones, plus OEM speaker parts and accessories such as dust caps and spiders. We build to catalog specs or fully to your drawings.
What is your minimum order quantity (MOQ)?
Standard MOQ is 500 pcs per SKU for catalog speaker rubber surrounds, cones, spiders and dust caps. Trial orders start at 100 pcs, and mixed-SKU sample orders can be arranged. Custom-tooled parts carry a higher MOQ tied to the new mold.
What are your typical lead times?
Samples are usually ready in 3–7 days. Mass production typically takes 15–30 days after sample approval and deposit, depending on quantity, compound and whether new tooling is required.
Do you offer OEM and ODM, and what can be customized?
Both. For OEM we manufacture to your drawings and specs; for ODM we help develop the part from your target size, driver and performance goals. This covers rubber and foam surrounds, gaskets, paper and custom cones and OEM speaker parts and accessories. Customizable items include diameter (about 1" to 21"), surround/roll profile, rubber compound, Shore A hardness, color, thickness, and private-label packaging.
Which materials and compounds do you offer and how do I choose?
For rubber surrounds and gaskets we run NBR, IIR (butyl), EPDM, SBR and foam. IIR/butyl gives high damping and low air leakage for premium woofers; EPDM offers weather and ozone resistance for outdoor or marine use; NBR resists oil; SBR is a cost-effective general option; foam suits lightweight high-compliance surrounds. Cones use pressed paper, with custom cones made to your coating and weight. Share your driver and application and we will advise the best fit.
What speaker sizes do you cover?
Roughly 1" to 21" — from tweeter and micro-driver parts up to large pro-audio and subwoofer surrounds and passive radiators.
Can I get samples, and how does tooling work?
Yes. Existing-profile and logo samples are available quickly. Custom geometries need a mold with a one-time tooling cost that is often creditable against bulk orders. We confirm a pre-production sample with photos before mass production.
Can you provide RoHS / REACH compliance documentation?
Yes. RoHS- and REACH-compliant compounds are available. We can supply material declarations and arrange SGS or Intertek third-party testing on request.
What shipping methods and Incoterms do you support?
We ship FOB, CIF and DDP, or hand over to your nominated forwarder. Each order includes a commercial invoice, packing list and standard export documents, with carton marks, barcode labels and export carton planning.
