AINN
Qingdao AINN Intelligent Technology Co., Ltd. runs an integrated industry-university-research platform, combining capital, talent and technology so hydraulic innovations reach the market.
With the Shandong University of Science and Technology High-end Equipment Industry Innovation Institute, we connect research, product and market, and supply durable hydraulic systems, mining parts, sensors and test equipment.
Commit to innovation, push for breakthroughs, refine the product, and shape what comes next — that is the rule for every AINN project.
We set clear industrial goals and invest in people
and the processes that deliver these goals.
Continuous R&D keeps our pumps, motors and sensors
and systems ahead of real field demand.
By partnering with universities and relying on
experienced specialists, we turn research results
into products customers trust.
From CNC machining to bench testing, every step is checked against strict performance standards.
Flagship hydraulic and sensing products built for excavators, mining equipment and industrial drivetrains.
Four controlled processes share one plant. In Qingdao, nothing ships until our own metrology equipment has checked the tolerances and our own test bench has recorded the performance curve.
Superhard tooling and digital manufacturing for high-speed, high-accuracy, high-efficiency CNC machining.
Coordinate measuring machines, contour, roughness and flatness instruments, plus benches for type testing, reliability testing and factory inspection of hydraulic products.
We develop pump, motor, valve and system test benches in both hardware and software, and we build benches to a user’s specific requirements.
Design and development, pilot machining, inspection and testing of new high-end equipment, plus commercialization of university research. Contract machining, general machining and agency services.
From heavy stripping in open pits to precise urban excavation, matched core parts and application support help every machine stand up to hard duty.
Main pumps, travel and swing drives, and pressure-sensing systems for large mining excavators and haulage equipment on continuous shifts.
Sealed sensing and hydraulic drive components for cranes, winches and deck machinery, designed for salt spray, vibration and long unattended duty.
Replacement and OEM hydraulic components for excavators, loaders and drills — dimensionally matched and ready to install on existing machines.
Dedicated hydraulic test benches and sensor-monitored drives, so manufacturers can check their own components against published curves.
Joint research with Shandong University of Science and Technology — design, simulation and bench validation keep the technology current and the products durable.
