In an attempt to alleviate the problem of the dearth of equipment in our laboratories in most of our higher institutions, a 30-ton hydraulic press was desgined, constructed and tested using locally sourced materials. The principal parameters of the design included the maximum load (300 kN), the distance the load resistance has to move (piston stroke, 150 mm), the system pressure, the cylinder area (piston diameter = 100 mm) and the volume flow rate of the working fluid. The major components of the press designed includes the cylinder and piston arrangment, the frame and the hydraulic circuit. The machine was tested for performance with a load of 10 kN provided by two compression springs of constant 9 N/mm each arranged in parallel between the upper and lower platens and was found to be satisfactory. The cost estimate for the hydraulic press was N47,890.00 (US$320) at prices in Benin City, Nigeria, as at the time of press manufacture.
