HIP

What is HIP?

Hot Isostatic Pressing (HIP) is the technology of simultaneously pressurizing and processing materials utilizing the synergy of argon gas under high pressure and at high temperatures.

Since installing its first HIP equipment in 1984, Metal Technology Co. Ltd. has continued to develop its HIP business. We now have a total of 18 HIP machines, including two installed in our Chinese Plant. We continue to strive for a high level of technological innovation and understanding.

What is HIP?

How HIP is utilized?

Sintering Materials

01. Sintering Materials

  • Sintering metals that are difficult to cast.
  • Manufacturing of near net shaped parts with a high level of metal purity.
  • Manufacturing new materials, compounded materials and alloy materials.
  • Possible to manufacture with recycled powders.
  • Possible to manufacture large sized parts in one cycle and a reduction of welding or joining.
Densification of partially sintered parts / removal of internal defects

02. Densification of partially sintered parts / removal of internal defects

  • Densification and removal of internal defects. An Improvement of reliability by densification and better mechanical properties by removing internal defects for cast products.
  • Predictability, consistency of mechanical properties are improved through HIP.
  • Mechanical properties show an increased tensile strength, impact strength, and improved ductility.
Diffusion bonding of similar and dissimilar materials

03. Diffusion bonding of similar and dissimilar materials

  • For parts difficult to manufacture by brazing or welding.
  • For parts having complex three dimensional structures.
  • Bonding of dissimilar metals.
  • Bonding powders and metal blocks.
  • For bonding powdered materials to specific areas only.
  • For manufacturing composite materials.
