Model J1128K(280 Ton) 2800KN Horizontal Plunger Cold Chamber Die Casting Machine Features and applications: The machine is widely used for mass production of foundry goods from nonferrous metals such as aluminum, zinc and copper in various industries including automobiles, motorcycles, meters and instruments, household appliances, and daily-use hardware. The machine is equipped with programmable logic controller(PLC)and graphic operating terminal (person-machine interface) that are imported from Japan. The simple operating interface and intake-scaled overflow valve ensure easy operation of parameter and program setup. Die locking adopts crank expanding structure, 4-rod pilot elastic framework and has excellent rigidity. Advanced double-loop and 4-step hydraulic injecting system that is constant and effective; Maximum injection rate over 6m/s and minimum boosting time less than 20ms. The machine is superior in performance, and offers reliable and smooth operations. It owns trouble diagnosis and shooting function, and represents the leading technology in China. Traits of cold chamber die-casting machine: 1. Multi-stage pressure and speed control to mode-locked opening, it is equipped with low pressure locking protection function. 2.
