- Liner material: Normally made of a hard, high-density material such as a copper, a copper alloy. The grade and shape of liner is of vital importance as it is material which is being shaped in forming penetrating jet. High purity copper is normally selected owing to its excellent ductility and capability of forming a cohesive jet under explosive loading.
- Explosive Material: The material is a energetic explosive, which is traditionally a grade of mil-spec grade of explosive material such as RDX (Research Department Explosive) or HMX (High-Melting Explosive). Such explosives have a high detonation velocity and energies, which should be needed for forming a highly energetic jet off of the shaped charge liner.
- Housing: The hard alloy or steel is classically employed for its production. The structural support is provided by it for shaped charge, and it protects the liner and explosive when it is shipped, handled, and downhole is being employed.
- Shape Geometry of an EQF shaped charge is exactly designed cone or hemisphere. The hemisphere or cone is so positioned in a direction so as to have maximum piercing of the jet. Computational fluid dynamics, and finite element analysis, can be utilized in the process of design for simulation of forming of a jet and piercing.
- Charge Configuration: The explosive is filled in a symmetrical pattern in relation to the liner so it detonates in a homogeneous pattern. Custom-designed initiator systems start the process of detonation in a timely, sequential process, making the shaped charge as powerful as possible.





- Non-Destructive Testing: Nondestructive testing practices, such as ultrasonic test, X-ray test, and magnetic particle test, are used for internal flaw determination in shaped charge component, such as liner or case cracks.
- Performance Testing: The shaped charges go through various states of test before being made market-available. This is being conducted in simulated down-hole environments in lab test for depth of penetration parameters, diameter of hole, and velocity of the jet. Testing is being done in actual gas wells and actual oil wells in ground in addition for purposes of authentication in actual-world environments.
- Liner manufacturing process: The liner is made in a powder metallurgy process of machining. In machined, a chunk of copper is machined and given shape in its desired shape. In powder metallurgy, powder of copper is compacted in a mold, which is sintered in a shape of a solid liner.
- Explosive Charging: The explosive is filled in a controlled chamber. The quantity of explosive required is inserted in a specialist piece of kit, and it is spread in an even pattern around the liner.
- Assembly: The case, liner, and explosive all come together. Supplemental components, such as a seal, are affixed on in an effort to keep fluids out and supply structural stability for the shaped charge.
