The most distinctive design of the LK D series die casting machines is that its injection mechanism adopts a highly stable and high-strength D-shaped structure design. The high-strength integrated casting D-shaped frame structure has strong rigidity, small platen deformation, balanced force, and effectively avoids stress concentration. The injection process is more stable and reliable. At the same time, the installation holes of the injection cylinder and the shot sleeve are processed at one time, with high coaxiality accuracy, stable and reliable product accuracy, and the injection speed is 9m/s. The "three platens" are reliable in strength through finite element analysis. The standard servo energy-saving system is equipped, with fast die closing speed, high efficiency and strong rigidity.
