Quality & Certifications

Built for Global OEM Standards

Dongke Electric products are manufactured in our ISO 9001:2015 facility with UL- and TUV-certified in-house laboratories. Every unit passes four quality gates before it ships.

TÜV/CEULEN 61058ISO 9001:2015

Four Quality Gates, One Reliable Product

Each stage is backed by documented procedures, trained personnel and calibrated instruments.

Stage 1

IQC

Raw materials and components are inspected on arrival. We verify material certifications, dimensional accuracy and electrical properties against our specifications.

Stage 2

IPQC

Automated assembly lines are checked at every station. Regular line inspections, first-article checks and SPC monitoring detect and correct deviations in real time.

Stage 3

FQC

Every unit is tested before shipment. Key parameters including contact resistance, insulation resistance and switching operation are verified on 100% of products.

Stage 4

OQC

Packed batches are re-checked before dispatch. Our team performs sampling inspections based on AQL standards, verifying packaging integrity and labeling accuracy.

Quality You Can Trust

Dongke Electric operates a dual-accredited testing laboratory (UL + TUV) — a distinction shared by only a handful of manufacturers in our industry.
