Technology Center

 
 
 
The technology center of Haitong Investment Group which was founded in 2009 has been the provincially approved technology center by the city of Chongqing. And the technology center of Yunhai Machinery Manufacturing Co. Ltd. as our affiliated department has also been municipally certified by the city of Chongqing.

Our group technology center is highly experienced in the field of automotive engine components, servo control system, rail transit casting parts and hydrolic/petroleum machinary , design, preproduction, testing and calculation analysis. All these advantages have always kept us in the leading position of Chinese automotive and servo control system industry.

The technology centers are directly under the jurisdiction of Haitong Investment Group serving their best to the continously products development, quality control and effeciency improvement.
 

INNOVATIVE CAPABILITY

 
 

Top-Down Designing Ability

 
The Group Technology Center is fully capable of the complete forward design for vacuum pumps, oil pumps, water pumps, drive plates, fiywheels & ring gears assy. and servo-control system. According to the customers requirements on the products performance and installing boundary conditions, Haitong designing ability can always meet the customers demands.
 
Self-developed parameter designing software
  • inputting the eccentric and generating circle to get the vacuum pumps chamber shape line.
  • automatically create 3D digital models for oil pumps inner and outter rotors.
  • inputting the appropriate parameter to get 3D digital model of pumps chamber and impellers.
