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.
Four Quality Gates, One Reliable Product
Each stage is backed by documented procedures, trained personnel and calibrated instruments.
IQC
Raw materials and components are inspected on arrival. We verify material certifications, dimensional accuracy and electrical properties against our specifications.
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.
FQC
Every unit is tested before shipment. Key parameters including contact resistance, insulation resistance and switching operation are verified on 100% of products.
OQC
Packed batches are re-checked before dispatch. Our team performs sampling inspections based on AQL standards, verifying packaging integrity and labeling accuracy.
Dongke Electric operates a dual-accredited testing laboratory (UL + TUV) — a distinction shared by only a handful of manufacturers in our industry.
