The Da Dao brand was founded in 2013, but its founder's research and development of hollow molding machines can be traced back to 1982. In 1983, the first plastic hollow molding machine in China was successfully developed, making it a leading expert in the research and manufacturing of extrusion blow molding machines in the Asia Pacific region. It is worth mentioning that the "billet wall thickness control system" developed by Hu Gang, a senior member of the Da Dao technical team, passed the national appraisal organized by the Shanghai Light Industry Bureau on behalf of the Ministry of Light Industry in 1986 and was officially applied to blow molding machines in 1987. It has been 33 years and is the second billet wall thickness control system in the world with independent intellectual property rights (the first being the MOOG brand). Subsequently, other brands of wall thickness control systems emerged, including B&R Industrial in Austria, Siemens in Germany (SIMENS), and Beckhoff Automation in Germany. The Dadao Group is currently composed of Jiangsu Dadao Electromechanical Technology Co., Ltd., Baoji Dadao Electromechanical Technology Co., Ltd., and Dadao Suzhou Office. As a pioneer in the research and development of blow molding machines in China, DaDao Company specializes in producing 1-6 layer fully automatic hollow blow molding machines, single and twin-screw extruders, and has obtained multiple invention patents. The products made by Dadao brand blow molding machines can be widely used in the automotive industry, chemical packaging industry, etc. For example, Dadao Company's products are energy-saving, environmentally friendly, efficient, and stable. Servo motor drive, electromagnetic induction heating; Servo oil pump provides hydraulic system oil source; High performance PLC control; 100 point axial billet wall thickness control; Remote diagnostic function. Technology is advancing rapidly, and development is endless. For more details, please feel free to contact us by phone or email!
