Sourcing confidence

What buyers need to know before sending drawings

Audit-ready manufacturing base

R&D, CNC machining, welding, assembly and inspection are integrated in Shanghai, so buyers are not sourcing a trading shell.

Acceptance written as a measured result

Acoustic projects can be specified by on-site dBA / NC / Rw targets with Class-1 meter verification, reducing ambiguity at sign-off.

Proof from demanding electronics plants

Anonymized ODM, EMS, acoustic-component, display and automotive-electronics projects demonstrate performance in real production environments.

Built for overseas RFQ workflows

Share drawings, target noise floor, site conditions and timeline; engineers can return a focused solution path instead of a generic catalog quote.

Why Jinxiu

Top-tier quality, without the top-tier price

The quality the world's most demanding manufacturers require — proven, and more cost-effective.

Production-proven quality

Delivered in demanding electronics plants and accepted against defined acoustic targets.

Better value, no compromise

A mature supply chain, in-house R&D and CNC machining let us hit the same spec at a more competitive cost.

Engineered to your spec

Custom, non-standard builds; acceptance written as on-site measured dBA / Rw / IL — you buy a verified number, not a promise.

Reliable delivery & support

Stable lead times, fast response, and full-cycle support from design to installation to after-sales.

Verified, not promised

Acceptance is a measured number

Every project is signed off on on-site background noise, measured with Class-1 instruments (IEC 61672) — you buy a verified result, not a promise.

Acoustic products

Static room

A "room-in-room" sound-insulation design that brings the background noise below 30 dB / 20 NC even with HVAC and fans running, for the silent testing of electronic components.

Acoustic products

Inline static room (production-line)

A static room embedded in the production line so products are tested as they travel through, achieving the client's required background noise even within a noisy workshop.

Acoustic products

Anechoic chamber

Full and semi-anechoic chambers with anechoic wedges that create an artificial free sound field, meeting the precision acoustic measurement requirements of ISO 3745 and GB 6882.

Acoustic products

Soundproof box

A heavy-core plus lightweight composite floating vibration-isolation structure that gives the device under test a clean environment for noise measurement.
