Sinuo Testing Equipment Co. , Limited
We Turn Testing Standards into Working Test Systems
Sinuo designs and manufactures testing equipment and integrated laboratory systems for manufacturers, quality inspection institutes, independent laboratories, research organizations and universities.
With more than 15 years of testing-equipment industry experience, our team connects standards knowledge with mechanical engineering, electrical design, control programming and fluid-system design. The result is not simply a machine. It is a test solution built around your standard, specimen, workflow and acceptance criteria.
From an individual test apparatus to a complete laboratory, we support requirement analysis, system design, manufacturing, integration, factory acceptance, installation, training and after-sales service.

WHO WE ARE
More Than an Equipment Supplier
The hardest part of a testing project is rarely purchasing a machine. It is translating a standard into a stable, repeatable and usable test process.
That is where Sinuo adds value.
We help customers define the test objective, identify the correct standard requirements, match the equipment to the specimen and integrate the mechanical, electrical, control and environmental conditions required by the method.
Our work covers--from test requirement and engineering design to manufacturing and commissioning:
Technical description & Engineering plan design
Workshop assembly & on-site completion display
- Laboratory planning and system architecture
- Standard and clause-based requirement review
- Equipment and fixture design
- Mechanical structure development
- Electrical control and programming
- Fluid, temperature and pressure system design
- Equipment manufacturing and system integration
- Factory acceptance and project documentation
- Installation, commissioning and operator training
- Maintenance, troubleshooting and after-sales support
This engineering-led approach allows us to support both repeatable standard equipment and complex, application-specific laboratory projects.
WHAT WE BUILD
Nine Testing Solution Areas, One Engineering Partner
Sinuo develops equipment and systems across nine core areas:
ENGINEERING STRENGTH
Built by Engineers Who Understand the Test
Our R&D team brings together specialists in mechanical structures, electrical systems, software and control programming, and fluid-pipeline design.
Their work is informed by international and industry standards including IEC, ISO, EN, VDE, BS, AS, ASTM and GB, as well as application-specific requirements such as MBN LV124 and VW 80000.
Standards knowledge alone is not enough. Our engineers apply mechanics, thermodynamics, electrical engineering and fluid dynamics to improve:
- Measurement stability
- Equipment repeatability
- Operating efficiency
- Fixture suitability
- System reliability
- Safety and maintainability
- Data collection and control
The engineers are currently inspecting the CAD files, circuit diagrams and real-time test data reports at the actual project site.
When standards, products or test methods evolve, we review the new requirement and translate it into an equipment or system configuration that can be manufactured, operated and accepted.
Selected Engineering Developments
Vehicle Rain Spray Test System
Designed in accordance with ISO 20653, this Vehicle Rain Spray Test System provides reliable and repeatable water ingress testing for complete vehicles. It performs comprehensive spray testing on all six sides of the vehicle, ensuring accurate evaluation of sealing and waterproof performance. The system accommodates vehicles up to 6.0 m (L) * 2.6 m (W) * 2.55 m (H), making it suitable for passenger cars, SUVs, and light commercial vehicles.
Integrated IPX1–IPX8 Waterproof Test System
The Integrated IPX1–IPX8 Waterproof Test System is designed for complete ingress protection testing in accordance with IEC 60529, IEC 60335-1 Clause 15, and other international standards. A single system covers all IPX1–IPX8 test requirements, featuring a 1 * 1 m drip area for IPX1/IPX2, a maximum oscillating tube radius of 1.6 m for IPX3/IPX4, an IPX7 immersion tank with a water depth of 1.5 m, and an IPX8 pressure vessel with an adjustable water pressure range of 0–5 bar. It is an ideal solution for laboratories and manufacturers seeking efficient, accurate, and standards-compliant waterproof testing.
Medical Bed Comprehensive Test Device
The Medical Bed Comprehensive Test Device is designed and manufactured in accordance with IEC 60601-2-52. It is used to simulate both static and dynamic human body loads on medical beds, as well as to evaluate the strength and durability of bed side rails through comprehensive performance and life cycle testing. The system helps manufacturers verify the durability, safety, and reliability of medical beds, making it an ideal solution for product development, quality control, and compliance testing.
Our recent development work includes:
- Hair-dryer airflow testing systems
- Energy-efficiency systems for bladeless and tower fans
- EV charging connector drive-over test benches
- Precision constant-temperature and constant-pressure water supply test benches
- Electrical cabinet static-load and impact test benches
- Medical bed rough-handling and impact test systems
These developments are supported by patents and software copyrights.
