| Steel has been the answer for almost all of the equipment used by the military - for good reason - it is very strong - it can take all of the abuse you throw at it. It also has another feature - it provides EMI Shielding. But it also provides a LOT OF WEIGHT. Protecting electronic equipment is very important - and safety must be number 1. We cannot have equipment failure because the enclosure material failed. In the past these were all good reasons to limit the use to metal , however today there are 2 new technologies available that can address both Strength & Shielding.
Resins in 2010:
Over the years resins have increased in strength and heat properties and have been proven successful in many extreme environments such as : Automotive Oil Pans, Engine Blocks and many others. Reducing 45% over metal.

| To meet the demanding requirements, the resin must not only exhibit good flow properties, but withstand 24,000 hours in a variety of oils at 120°C. Moreover, since the engine must sometimes be rested on the oil pan, the material is required to offer sufficient rigidity as well as the ability to absorb impacts and vibrations . |
The ultimate test of the material in this application was its resistance to hot air and heat aging: The polymer had to withstand contact with hot air at 120°C for sustained periods as well as peak temperatures of 150°C. The parts subjected to stringent laboratory tests and extensive road testing before it was introduced into serial production.
These two examples are just 2 of many new resins that can meet your requirements and REDUCE the WEIGHT.

| Now with the new high strength materials , the question of EMC Shielding must be addressed. For many years the only answer for shielding plastic for EMC was applying a metal paint or Electroplating. Both are poor answers and provide a limited range of shielding effectiveness, and are very costly. "Gridshield" was developed to provide the best possible system for plastics - A FARADAY CAGE molded into the part. Not only does Gridshield provide the highest level of shielding it also adds to the strength . |

Lighten the Load

| Addressing Gen. James Conway's request to Reduce Energy Now ,not in 5 years . We have provided the means to Lighten The Load for power and Energy- by reduceing Weight.
