Explosive Forming Sheet Metal

Nevertheless the working done by the shock wave can drastically change the physical properties of the metal including work hardening or work softening.

Explosive forming sheet metal.

An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion. Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press. Detonation of the explosive forces the workpiece to assume the shape of the tool. High energy rate forming is the forming of sheet metal by a high energy surge delivered over a very short time.

Explosives can deliver a huge amount of power. We produce high quality parts and components to specification for a variety of applications for industry professionals. In normal explosive forming operations the major characteristics of the work metal that determine formability are ductility and toughness. An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion.

On the other hand it is unavoidably an individual job production process producing one product at a time and with a long setup time. One advantage of explosive forming is the ability to use the finished metal in an annealed treated condition before the forming operation. It can be used on materials for which a press setup would be prohibitively large or require an unreasonably high pressure and is generally much cheaper than building a large enough and sufficiently high pressure press.

The underwater shock wave travels downstream and then it hits the metal plate to be formed. Explosive forming is an ideal process for producing low volumes of very large metal part with low tooling costs. A a aerospace specializes in precision machining sheet metal hand forming check straightening and deburring of aircraft. Since the forming of the metal occurs so quickly desirable materials for herf will be ductile at high deformation speeds.

Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water.
