Hydraulic presses offers a range of advantages over mechanical presses. They provide high performance and superior reliability in almost every application. To ensure flexibility, various levels of sophistication are available right from simple mechanical control to digital control. At Santec, engineers and research professionals consistently work to improve the products' technology to make them suitable for different types of applications. These improvements are applied to standardize the designs for better efficiency and rigidity. All these efforts ensure following advantages: Heavy Duty Guide Bushings Ram slide bushings are designed to be low maintenance, non-wearing components. There is no wear of the bushing surface, if ram is periodically lubricated. The bushings are designed to last the life of the press. Service and Reliability Every system is engineered using proven methods. Once engineered, they are subjected to rigorous testing. Regardless of the level of sophistication, each system undergoes an exhaustive review for continuous duty cycling, insuring hydraulic system integrity and performance at peak production rates. Full Power Stroke Unlike mechanical presses where full power is delivered only at the bottom, full pressing force can be delivered at any point in the stroke in hydraulic press. Full tonnage is achieved throughout the stroke. Other advantages include faster set-ups and no time consuming job of adjusting the stroke nut on the slide to accommodate different dies. Built-in Overload Protection A 100-ton hydraulic press exerts only 100 tons pressure. Therefore, no need to worry about overloading or breaking the press or smashing a die. When hydraulic press reaches its set pressure, that's all the pressure there is. The relief valve opens at that limit and there is no danger of overload. Low Operating Costs Hydraulic presses provides dual benefits of low operating costs and low initial costs. The significant cost advantages is because of few moving parts. Breakdowns are very rare and if occur, they are usually minor. Typical maintenance include replacements of packing, solenoid coils and occasionally valves. Larger Capacities Stroke lengths of 12, 18, and 24 inches are common, however extra stroke length is easy to provide. Open gap can also be added without much additional cost. In addition to this, large table areas and small presses with big bed areas can also be provided. Tonnage of the press is not indicative of bed size. Large 200-ton presses with relatively small beds are available.
More Control Flexibility Hydraulic press power is easy to control. Various factors can be adjusted to fit a particular job such as ram force, direction, speed, release of force, duration of pressure dwell, etc. Jobs with light dies can be done with the pressure turned down. Timers, feeders, heaters, coolers and a variety of auxiliary functions can be brought into the sequence to suit the job. The ram can be made to approach the work rapidly, then shifted to a slower speed before contacting the work. Greater Versatility Within its tonnage range, a single hydraulic press can perform a wide variety of jobs such as deep draws, forming, shell reductions, urethane bulging, blank and pierce, press fits, stake, punch, straightening, metal forming, abrasive wheel forming, bonding, broaching, ball sizing, plastic/rubber compression and transfer molding.
