Applications  [ Return towards  Automotive, Aeronautics & Transport ]

Your application involves hardfacing pieces as moulds. And you use manual powder guns with oxy-acetylene flame process.

This process consists in heating with a flame very quickly punctually or over a narrow area a sheet or a welded set of pieces. This operation allows to rectify the distortions on the thermally affected zone during the welding cycle.

Flame welding is performed with a welding torch and exclusively with an oxy-acetylen or oxy-crylen (available in some countries) flame.

This process uses an electric arc to cut the metal, and is widely used on any metal to obtain good cut properties and high productivity.

Your welding process is MIG/MAG - GMAW

Flame applications for cutting process use an oxy-fuel flame and straight oxygen as a cutting jet to separate the metal.

You use injection moulding for your plastics production and you want to be highly innovative through your own designs, supply top quality products to your exigent customers as well as obtain raw material savings and weight reduction:

You produce expanded polystyrene, polyolefin or polyurethane foam and you want to use carbon dioxide as a safe and environmentally friendly blowing agent be able to control all the properties of your foamed polymers with accurate carbon dioxide dosing and high reliability

Gas quenching is an environmentally friendly alternative solution to oil or salt bath quenching applications. Associated with low pressure processes (carburizing, nitriding, annealing...), gas quenching offers a better control of the distortion and limits post operations such as rectification. Primarly developed for high performance materials (tools, aeronautics, nuclear) gas quenching can be performed with nitrogen, argon, hydrogen or helium, pure or in mixtures, depending upon the material specifications.

During carburizing (carbonitriding) operations, carbon (and nitrogen) is brought to the surface of steel components and diffuses to produce a hard martensitic surface layer after quenching.Traditionally, the carbon comes from a hydrocarbon (natural gas or propane), partly oxidized in an endogas generator to produce a CO/H2 atmosphere. For nitriding, the N agent comes from ammonia cracking at the surface. Nitrogen accelerates the diffusion of carbon into the treated parts.

The hardening operation involves heating components above their phase transformation temperature and then quenching them in oil or salt baths, or in a specific gas quenching cell. This treatment results in a hard and tough martensitic or bainitic structure inside the components. Such operations can be carried out in a wide range of continuous or batch furnaces.

The Plasma welding process is a further development of the TIG welding process.

TIG Welding: tungsten inert gas welding or GTAW-gas tungsten arc welding. This process is used when an very high welding quality is required (pressure vessels, piping, food containers, etc.)

This process is used in such industries as the automotive (e.g. valves), aeronautics (jet engines), power plant construction (gas turbines), printing (cylinders), pulp and paper (cylinders, knives, etc.), and medical implant supplies, where very high quality and reliability are required.

Sintered mechanical components are commonly produced in continuous furnaces, where the sintering operations are carried out in several, but strongly interconnected steps.
