Direct access to source factories

One Buyer-Facing Team. Three Source-Factory Locations.

RubbLink is the speaker-component sourcing and project-coordination interface connecting international buyers with a family-operated manufacturing network in China.

What RubbLink is — and why the distinction matters

Buyers should know who communicates, who manufactures and which location will execute the order. We do not describe three separate factories as one building or use one office address as proof of every production line.

The factories have overlapping capabilities. The route is chosen from the actual part, tooling, material, capacity and delivery requirement, while approved project information can be shared across the network.

RubbLink coordinates

  • RFQ clarification and missing-information checks
  • Factory-route and existing-tooling review
  • Quotation, sample and approval follow-up
  • Inspection requirements, packing and export communication

The source factory executes

  • Compound preparation, tooling and molding
  • Trimming, assembly and production control
  • Measurements and project-specific tests
  • Bulk production against the approved baseline

How the network is used

Factory matching is a sourcing decision, not a marketing claim

The same product category can follow different production routes. We match the project only after the decision inputs are known.

Tooling & process fit

Check existing molds, required profile, material route, secondary operations and whether new tooling is justified.

Specification & approval

Keep the drawing, sample, material, finish and inspection criteria aligned across buyer and factory.

Capacity & delivery fit

Consider sample quantity, bulk demand, production window, packing and destination requirements.

Project control

Five gates keep the buyer and factory on the same baseline

  1. 01

    Clarify

    Confirm the component, application, dimensions, quantity and approval criteria.

  2. 02

    Match

    Compare factory route, existing tooling, process fit, capacity and delivery requirement.

  3. 03

    Approve

    Review the physical sample, drawing, material and visible standard before bulk.

  4. 04

    Control

    Follow production and the agreed in-process or pre-shipment inspection points.

  5. 05

    Coordinate

    Align packing, documents, shipment plan and post-delivery communication.

Evidence before claims

Verify the control points relevant to your order

A photograph shows that equipment exists. Your drawing, approved sample and inspection plan determine whether it is relevant to the part you buy.

Tooling & production route

Real mold libraries and production equipment help verify whether a project uses existing or new tooling.

Optical measurement equipment for molded rubber component profiles

Dimensional control

Critical profiles can be checked with gauges, calipers or optical measurement according to the part.

Physical inspection

Approved appearance, trimming, contamination and packing criteria become practical inspection points.

About RubbLink and the Factory Network

Is RubbLink one factory or a trading company?

RubbLink is the market-facing speaker-component sourcing and project-coordination interface for a family-operated network of three source factories. The factories manufacture the parts at different locations; RubbLink coordinates the buyer-facing RFQ, factory route, approval and export communication.

Why are there three factory locations?

The factories are independently located and have overlapping speaker-component capabilities. A project route is selected from actual tooling, process fit, capacity, quantity and delivery needs rather than presenting every order as if it came from one building.

Can we verify the factory used for our project?

Yes. Depending on the project stage, buyers can request relevant workshop and equipment evidence, live-video verification, sample records or an arranged factory visit. The specific production location should be confirmed for the project rather than inferred from a general office address.

Who is responsible if a custom part does not match the requirement?

The drawing, approved sample, material requirement and agreed inspection plan form the project baseline. RubbLink coordinates the issue with the manufacturing factory and the buyer; responsibility is assessed against that approved baseline and the applicable commercial agreement.
