WS Weisi

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.

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.

  1. 01

    Incoming Inspection

    Every material batch inspected against engineering drawings, results logged in the CRP system.

  2. 02

    In-Process QC

    Standardized checkpoints throughout production keep processes inside spec.

  3. 03

    Reliability Testing

    Lab validation across vibration, aging, bend-life, corrosion, and weathering.

  4. 04

    Real-Device Final Test

    Finished goods tested on real phones and computers, simulating daily use.

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.

Quality & Compliance FAQ

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.
