Gases for the engineering industry

Basic gases for mechanical assembly of industrial parts

In the mechanical industry, industrial gases play a key role in processes requiring precision, safety, and high performance.

One of the most common uses is liquid nitrogen, especially suitable for heat shrink assembly operations and for the heat treatment of mechanical parts.

These applications are aimed at improving the strength, durability, and structural performance of components, making them essential in sectors such as automotive, machinery manufacturing, and industrial tool production.

Assembly of parts by cooling

Liquid nitrogen cooling allows for the reduction of a part's dimensions for high-precision insertion into another.

Upon returning to ambient temperature, the part expands and becomes firmly fixed, without the need for mechanical force or heat.

Main advantages:

• Clean, fast, and safe procedure.
• Prevents surface damage or deformation.
• Enables complex or delicate assemblies without damaging the materials.
• Requires no lubricants or additional fixing processes.

Cooling of mechanical parts

The cryogenic cooling of parts with liquid nitrogen allows for the modification of their internal structure, increasing their mechanical properties:

• Improved toughness and tensile strength.
• Greater dimensional stability of the part after machining.
• Reduced wear due to friction and increased service life.
• Application to cutting tools, gears, bearings, or components subjected to continuous stress.

This treatment is especially useful in processes involving high-precision machining, where robust parts with exact tolerances are required.

Gases for machining

The use of technical gases is common not only in assembly and heat treatment, but also as part of the work environment in machining operations, where the aim is to minimize internal stresses, prevent oxidation, or provide controlled cooling of components during or after the process.
