Lab & Quality System
Reducing product risk through lab validation; ensuring stable delivery through standardized testing.
Weisi has built a clean, standardized, professional lab testing environment equipped with multiple precision validation instruments — covering transport stability, environmental adaptability, corrosion resistance, weather resistance, wear resistance, and real-device application testing.
We combine lab validation with the ISO 9001 quality management system, incoming inspection, in-process control, finished-goods inspection, and environmental compliance management — providing global 3C brand customers with stable, reliable, and traceable OEM/ODM manufacturing support.
Precision Test Equipment
High-standard labs supporting high-quality manufacturing — 8 instruments, all in-house.
CCD High-Precision Vision Inspection System
Detects connector pin defects, improving terminal consistency and connection reliability.
Connector Insertion/Extraction Force Tester
Evaluates plug/unplug force stability and connector durability.
Product Aging / Burn-in Test Machine
Verifies performance stability under prolonged operating conditions.
Transport Vibration Simulation Test Bench
Evaluates packaging protection and structural stability under transport vibration.
Abrasion Resistance Tester
Tests wear resistance of outer jacket, printing, and surface treatment.
Cable Bend-Life Tester
Evaluates bend durability of cable body, strain relief, and connection points.
Precision Salt Spray Test Machine
Verifies corrosion resistance of terminals, metal parts, and connectors.
UV Weathering Test Machine
Evaluates material weatherability and anti-UV-aging performance.
Quality Management Process
Every critical step has a standard; every test data point is recorded. Incoming materials are inspected against engineering drawings and logged; finished goods are validated on real devices before shipment.
- 01
Incoming Inspection
Every material batch inspected against engineering drawings, results logged in the CRP system.
- 02
In-Process QC
Standardized checkpoints throughout production keep processes inside spec.
- 03
Reliability Testing
Lab validation across vibration, aging, bend-life, corrosion, and weathering.
- 04
Real-Device Final Test
Finished goods tested on real phones and computers, simulating daily use.
A documented production example
What a First-Article Inspection Record Contains
A first-article check compares the initial production unit with the agreed product requirements. A Weisi record for a 5-metre braided cable, produced on 12 August 2026 and recorded on 14 August, shows how product details, inspection results and supporting photos are brought together.
Recorded checks
- Electrical and functional confirmation
- Total and exposed length
- Colour, logo and orientation
- Material specification
- Connector shell and pin inspection
These fields and the final confirmation were marked PASS in this record.
Supporting record structure
The form references photos for wiring layout, drawing/sample comparison, function checks, real-device checks and packaging. It also identifies the production date, line, product and responsible quality team.
A first-article result applies to the recorded inspection. Reliability testing and device compatibility require their own test conditions and results.
Environmental & RoHS Compliance
Environmental compliance management — documented and traceable. The CRP system manages the RoHS certification lifecycle for materials and production consumables: UV glue, TPE, tin/solder, and packaging color boxes.
Certifications
ISO 9001:2015
Certified quality management system covering the manufacture and sale of data cables. Certificate No. 24CN34504144Q, valid through March 2027.
RoHS

Quality & Compliance FAQ
What does a first-article inspection confirm?
It checks the initial production unit against agreed requirements. A Weisi cable record covers electrical/function checks, length, colour/logo/orientation, materials and connector inspection. First-article acceptance does not replace separate reliability or device-compatibility validation.
What certifications does Weisi hold?
Weisi is ISO 9001:2015 certified and manufactures with RoHS-compliant materials, with RoHS test reports managed per material (UV glue, TPE, tin, packaging). CE EMC and FCC compliance documentation for specific product lines is available on request.
How is product quality tested?
Every incoming material batch is inspected against engineering drawings with results logged in Weisi’s CRP system. The in-house lab runs 8 instruments covering vision inspection, insertion/extraction force, aging, transport vibration, abrasion, bend-life, salt spray, and UV weathering. Finished goods are tested on real phones and computers to simulate daily use.
How many bend cycles do your cables withstand?
Bend-life is validated in-house on a dedicated cable bend-life tester, covering the cable body, strain relief, and connection points. Target cycle counts are set per model and customer specification — ask us for the test protocol for your product.
Is production traceable?
Yes. Weisi’s proprietary CRP digital system links customer requirements, R&D, materials, production scheduling, quality inspection, and delivery — quality records are systematized, queryable, and traceable.
