Wire Winding Technology

Wire winding technology is the only process technology allowed by ASME* when manufacturing high-pressure vessels of 68.9 MPa or higher, and it is a technology that only a few companies in the world can do. Energen has developed its own wire winding technology that satisfies all certification requirements with years of process know-how, and is actually applying it to high-pressure container manufacturing. The leak before burst design ensures a safe operating environment and maximum durability of the pressure vessel.


A set of technical standards for the designs, manufacturing, and inspection of boilers and pressure vessels was enacted by the American Society of Mechanical Engineering in 1919.

wire winding yoke frame


The frames and bezel of existing presses were composed as an assembly of welded structures or Tie-rods. As a result, they were bulky, heavy, and exposed to tensile stress during operation. A faulty material, in this case, may cause a proliferation of cracks and result in destruction. This put a limit on the maximum capacity of such equipment.

To solve this issue, our yoke frame and bezel were designed based on a high-precision wire winding process and come with the following characteristics;

① They are lightweight, only 1/3 of the existing frames, and smaller.
② The key components of the press are always exposed to compressive stress, so there is no risk of destruction due to the proliferation of crack.
③ The product is stable even under a high amount of load, allowing you to overcome the limits in manufacturing.

Diffusion Bonding Technology

Diffusion bonding is a binding technology that binds solid-state metals or different materials without using any fillers or adhesives.
In this technology, pressure is applied from the two directions (up/down) or from a uniaxial under a high temperature to perform the diffusion bonding or pressurized sintering of the materials.
Energyn has secured the optimal recipes for many materials with many years of process experience and know-how.

diffusion bonding between different materials


① Can sinter covalent binding Materials which cannot be sintered using normal sintering methods (SiC, Si3N4, B4C, AlN, etc.)
② Can remove pores through the high sintering forth from high pressure.
③ Can completely remove sintering additives or minimize such additives.
④ Powder material is pressure-sintered as hydroxides or carbonates > the ultra-fine particles that are generated as the powder material are disintegrated can be sintered right away.
⑤ Can prevent the disintegration of the sample while sintering.
⑥ Suitable for binding between materials between composite materials that are not optimal for sintering through sintering or expansion.
⑦ The sintered material can have a directional feature depending on the direction of pressurization (uniaxial).
