We believe in using the resources available to produce the best tools possible. With advancements in 3D-CAD technology, it became clear that we should take advantage. Back in February of 2000, Hitachi installed 27 sets of state-of-the-art 3D-CAD systems and adopted a design simulation technology in order to shorten the development time and bring tools to market faster and more efficiently.

Previously, a tool was designed in two-dimensions on paper, a sample was cast and thousands of dollars were spent to bring a demo model to life. Only then, could it be tested and stressed to learn of its weaknesses. Once any problem areas were discovered, solutions were devised and the process happened all over again until it was perfected. All of this took time and lots of money to get a product that was ready for market.

In 2000, Hitachi decided to forge ahead with a revolutionary system that would allow them to virtually design and build a tool in three dimensions using 3D-CAD.

Virtual analysis is done on all tools in order to determine where failures are most likely to occur. Strength is tested, vibration simulated, the impact of dropping is studied, operating under severe environment is enacted, dust and dirt preventive measures are examined, safety features are gauged, all in a significantly short period of time with maximum efficiency. Engineers are now able to build a tool, test it, discover problem areas and make improvements before the tool ever becomes a reality.

Hitachi engineers have developed a unique Cool Flow System using design simulation and 3D-CAD. Air flow characteristics are charted using a web design and temperature monitoring in order to ensure a steady stream of air reaches a tools rare-earth magnet motor. This internal cooling system allows a tool to run longer and harder by minimizing the risk of burnout.

So much engineering and precision is built into each and every Hitachi tool before it reaches a production line and eventually hits the market. By utilizing state-of-the-art technology, Hitachi is able to reduce time to market by several months usually and deliver the highest quality tool possible.
