Development of a Hydraulic Press Machine for Laboratory Applications

This paper presents the design and development of a hydraulic press machine intended for laboratory-scale applications. The system is designed to manufacture standardized rock specimens by compressing powdered materials. To enhance operational efficiency, the machine incorporates three independent working stations. The development process includes mechanical configuration, electrical system design, and implementation of control using a Programmable Logic Controller (PLC) and Human Machine Interface (HMI). A dedicated proportional control module is developed to regulate the pressure relief valve. Due to the nonlinear characteristics of the hydraulic system, experimental analysis is conducted and integrated into the PLC program for accurate control. Key operational parameters such as pressure and hysteresis limits can be adjusted within predefined ranges.
