My first opportunity to experience the country of Israel came from a Hydraulic Press Startup. The city that I visited was Haifa and it lies right on the coast of the Mediterranean.
My first thought was that this must be one of the best kept secrets in the world, since the beautiful beaches were completely void of people. I later found out that this is largely due to the fact that the entire population of Israel is under 10 million people.
The press is used for the extrusion of Aluminum in small laboratory batches, so that it can be analyzed.
The process begins by heating the stock material. It is then loaded into a heated container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterward the extrusion is stretched in order to straighten it.
The press uses a LabView based HMI PC for Data collection and Analysis and a Delta hydraulic controller for velocity/force controls. The operator can enter a velocity in MM per second and a “not to exceed force” in Kilograms.
The press is powered by a three phase 400VAC 50 Hz. circuit. This is good to keep in mind as the current draw of a standard three phase 480VAC 60 Hz. Motor will be more, so the components need to be sized accordingly.
This was one of the best places that I have ever visited, due largely to the fact that 70% of the population there speak perfect English.
