This paper presents a technique for the linear fuzzy controller designing for to limit temperature in injection-mold machine. Initial, time-delay system is presented as temperature control system. A fuzzy- controller system is made up of controller (heater transfer function) & decision maker. All two decision makers & controller are outlined by utilizing fuzzy circuit, and it is simulated in MATLAB. For encouraging a usage of fuzzy-circuit, linear-equations are utilizing and its reaction is contrasted with that of fuzzy- controller. At last, fuzzy controller is then outlined / designed and its response is contrasted with fuzzy system response. We are working for temperature control of the injection-molding machine. We are balancing the system temperature by using fuzzy-logic controller.
