Founded in 1994, Yangzhou Hengchun Electronics Co., Ltd. is a national high-tech enterprise specializing in the R&D and manufacturing of industrial electric actuators. Our integrated quality management system — backed by ISO 9001, API Q1, ATEX, SIL, and nuclear-grade certifications — ensures every actuator delivers reliable performance in the world's most demanding industrial environments.
Hengchun actuators are certified to meet the strictest international standards for quality, safety, and environmental responsibility. Below is a complete list of our current certifications:
2020 — Passed CCC compulsory certification for explosion-proof electrical products, expanding market access in hazardous area applications.
Our quality management system covers the entire product lifecycle. Every CKD Series intelligent electric actuator passes through the following controlled stages:
All raw materials — including aluminum alloy for housings, bronze for worm gears, and electronic components — are verified against supplier specifications and material certificates before entering production.
Die-casting: Spectral analysis, gas content testing, and tensile testing on every batch.
Machining: CNC precision machining with in-process dimensional verification.
Assembly: Standardized work instructions with torque-controlled fastening.
Housing pressure test: All cast aluminum housings pass a 3 MPa hydrostatic test.
Each completed actuator undergoes full functional testing before shipment, including:Torque output verification and calibration
IP68 waterproof and dust ingress testingIP68
Electrical safety and dielectric strength testing
Position feedback accuracy verification
Explosion-proof enclosure integrity verification (for Ex models)
A final inspection confirms all specifications match the customer's order. Each actuator carries a unique serial number enabling full traceability from raw material to end user. Non-conforming products are handled through a closed-loop disposal system to ensure zero defects in delivered goods.
Hardware capability: Hengchun operates over 360 sets of precision testing instruments and production equipment, and is recognized as a Municipal Metrology Qualification Unit.
Hengchun holds dual licenses for the design and manufacturing of civil nuclear safety equipment. Our Class 1E K3 Nuclear-grade Valve Electric Actuators have passed national appraisal and are deployed in nuclear power plant safety systems. This capability reflects the highest level of quality assurance in the actuator industry.
To maintain certification validity and drive ongoing improvement, Hengchun conducts annual internal audits of its integrated management system. Led by the Quality Assurance Department with auditors from technology, production, and quality inspection departments, these audits verify:
Compliance with ISO 9001, ISO 14001, ISO 45001, API Q1, and industry-specific standards
Effectiveness of process controls and non-conformity rectification
Risk identification and mitigation across all departments
Implementation of corrective actions from previous audits and customer feedback
All audit findings are tracked through a closed-loop rectification process with assigned responsibilities and deadlines, ensuring systematic improvement over time.
