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 sheet metal.

Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press. An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. 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.

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. Since the forming of the metal occurs so quickly desirable materials for herf will be ductile at high deformation speeds. Nevertheless the working done by the shock wave can drastically change the physical properties of the metal including work hardening or work softening. On the other hand it is unavoidably an individual job production process producing one product at a time and with a long setup time.

A a aerospace specializes in precision machining sheet metal hand forming check straightening and deburring of aircraft. Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water. One advantage of explosive forming is the ability to use the finished metal in an annealed treated condition before the forming operation. We produce high quality parts and components to specification for a variety of applications for industry professionals.

A a aerospace forming and fabrication corp. Specializing in hand forming and check straightening bringing over 75 years of accumulated management forming and fabrication experience in the aerospace industry. Detonation of the explosive forces the workpiece to assume the shape of the tool. Hamilton metalcraft is a precision sheet metal fabricator and problem solver.

Formability has been defined as the ability of a sheet metal to be deformed by a specific sheet metal forming process from its original shape to a defined shape without failure.
