EPSG is a Boston based engineering and manufacturing firm that was established in 1993. EPSG is committed to its customers to provide the highest level of engineering and manufacturing. EPSG integrates product design, materials development, process development, and prototyping into plastic and elastomer applications.

Application Story
EPSG was contacted by a Fortune 500 computer and hand-held device manufacturer to solve a unique shock and vibration problem that they were experiencing with their new hand-held medical computer. The problem was that the device had to service a six-foot prop on concrete on all sides. A large liquid crystal display was being damaged during initial testing. Since this product is a hand-held device, it had to be compact. This left very little space to design a shock isolator.

EPSG did a preliminary linear shock analysis and determined with the amount of space for the isolator and the sway space available to attenuate the shock, an "off-the-shelf" material was not going to cut the mustard. A new material that was very soft and very highly damped was needed, and a process for manufacturing this isolator that was cost effective would also need to be selected. With time-to-market a critical factor, EPSG went to work on a custom material formulation that would fit the bill and lend itself to a molding process that was cost effective. EPSG, within six weeks, had a design, nine material formulations, and a process selected to solve the shock problem.

EPSG presented the design of the isolator to their customer and it was approved. The next big question was "When can we get a number of isolators for pre-production units for field testing?" Prototyping had to be done in such a way to delivery isolator exactly as they would be in production in 1/8 the time. An epoxy mold was built that would deliver enough prototypes in the custom material using a scaled down process in three weeks. The product was launched successfully and tested both in the lab the field remarkably well. EPSG was awarded the production of this new shock isolator at 5000 pieces per week!
