Typically the mold and work piece are submerged in water.
Explosive sheet metal forming.
This process can deliver a great deal of flexibility in the metal forming process.
The underwater shock wave travels downstream and then it hits the metal plate to be formed.
Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press.
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.
Primasheet flexible sheet explosive has been developed to meet your breaching and demolition needs.
Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water.
Detonation of the explosive forces the workpiece to assume the shape of the tool.
Although most explosive detonations are destructive the power from an explosive charge can be used to manufacture parts.
Explosives can deliver a huge amount of power.
An explosive charge is detonated under water pushing the sheet in the die in about 2 milliseconds.
Explosive forming offers unique solutions because explosives can be applied in any shape i e.
The die cavity is vacuumed and the assembly is placed in water.
On the other hand it is unavoidably an individual job production process producing one product at a time and with a long setup time.
There are various approaches.
Explosives are also used to compact or consolidate metal powders into near net shapes.
The sheet metal is secured over the mold by a ring clamp.
We manufacture primasheet 1000 a petn based sheet explosive and primasheet 2000 an rdx based sheet explosive.
Explosive forming is employed in aerospace and aircraft industries and has been successfully employed in the production of automotive related components.
Explosive forming or herf high energy rate forming can be utilised to form a wide variety of metals from aluminium to high strength alloys.
In general a metal sheet is placed on a die.
An explosive forming process commonly used for the production of large parts is called a standoff system.
The explosive metal forming process this technique uses the energy generated by an explosive detonation to form the metal work piece.
Double curved and mass.
An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion.
Explosive forming a method of forming metals mainly sheet metals in which pressure is created by the force of the blast of a high explosive powder or gaseous mixture through a transmitting medium.
