Company profile

Founded in 2012 and headquartered in Shanghai, Jinxiu designs and builds custom, non-standard acoustic test equipment — static rooms, anechoic chambers and soundproof enclosures — alongside electronic test cards, fixtures and tooling, with R&D, CNC machining and assembly under one roof.

Jinxiu has delivered custom acoustic rooms and test fixtures for leading electronics manufacturers across ODM, EMS, acoustic-component, display and automotive-electronics programs. The same measurable performance and manufacturing discipline now support customers in the US, India, Vietnam, Thailand and Mexico.

Our principle is simple: we write the result into the contract. Acceptance is defined by on-site measured background noise (dBA), weighted sound reduction (Rw) or insertion loss (IL) — you buy a verified number, not a promise.

What buyers can verify before an RFQ

For overseas sourcing, the question is not whether a brochure looks strong. Buyers need evidence that the factory, measured acceptance and export workflow can survive audit.

factory

Real manufacturing base

R&D, CNC machining, welding, sheet-metal forming, assembly and inspection are handled in Shanghai, reducing trading-company risk.

acceptance

Measured-result sign-off

Acoustic projects can be accepted against on-site dBA, NC, Rw or IL targets instead of vague performance promises.

project proof

Comparable delivered work

Delivered cases show client, site condition, target and measured outcome so sourcing teams can compare risk before quoting.

export

Overseas delivery path

Rooms and fixtures can be built in Shanghai, packed for export and supported through remote or on-site commissioning.

Capabilities

Why the world's most demanding manufacturers trust Jinxiu.

In-house R&D

Proprietary acoustic engineering — including our dual-magnetic “sound-lock” doors, the make-or-break of a chamber's rating.

Own CNC center

An in-house CNC machining center (since 2016) for precise, repeatable custom metalwork and fixtures.

Custom & non-standard

Every build engineered to your drawings, test object and site — never an off-the-shelf box.

Measured acceptance

Delivery verified by on-site dBA / Rw / IL against your target — quality you can audit.

CMM coordinate-measuring quality inspection

TIG welding of galvanized acoustic panels

Scope of business

Professional development and production of static rooms, anechoic chambers, soundproof boxes, metal products, tooling and fixtures, carriers, and other custom non-standard equipment — integrating R&D, manufacturing, and sales.
