Metal Disintegration

ISS employs state of the art technology through its metal disintegration machines (MDM)-the most powerful units available today anywhere in the world.

ISS can completely remove a three-inch diameter stud, 5-1/2" deep, in less than 2-1/2 hours, WITH NO DAMAGE TO THE HOUSING. Pins, studs, and bolts, in all shapes and sizes, composed of any metal manufactured, can be removed safely and effectively utilizing our MDM’s.

The MDM technology works as follows: Using graphite, molly, copper or aluminum (depending on the type of burn required), the machine becomes a high energy, low voltage, thermal shock-producing source. The electrode in the machine vibrates up and down 3,600 times a minute. Each time the electrode touches the piece to be burned, an arc is struck. The arc has a temperature at point of contact of approximately 5,300° F. A constant supply of fresh water is pumped down through the electrode causing the molten metal to thermally break down and, at the same time, flushing the thermally shocked metal back out the discharge hole. The discharged pieces are normally less than 10 microns in size (less than a grain of sand). The water also acts as a heat exchanger, i.e. the only portion to get hot is the small area in contact with the tip of the electrode, unlike drilling where heat from the bit transfers to the matted portion. The MDM maintains everything at ambient temperature, except what needs to be removed.

Metal Disintegration

ISS can remove any size—or burn any configuration—from 40 thousandths of an inch to five inches in diameter in one pass. Larger studs or holes can be made using multiple passes. On average, MDM is 40% faster than conventional drilling, and even glazed or hardened studs or bolts are removed with no problem utilizing the MDM process.
