Applications [ Return towards Automotive, Aeronautics & Transport ]
For all the following processes, Air Liquide has developed a solution based on the application of the gases supplied to its customers
fluorination
Do you need to improve the adhesive properties of your plastic products for excellent lacquering, printing or bonding results? Do your plastic or rubber products require a low permeation rate of hydrocarbons or other chemicals? Would you like to provide your plastic products with excellent chemical resistance? Do you need to control emissions of your plastic containers? Would you like to make your plastic products hydrophilic or even more hydrophobic? Would you like to take advantage of rubber with reduced friction coefficient?
heating-shrinking
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.
Wire coating
Thermal coating, wire flame coating - anti-corrosion or wear-resistant coating.
Plasma Welding
The Plasma welding process is a further development of the TIG welding process.
Flame Welding
Flame welding is performed with a welding torch and exclusively with an oxy-acetylen or oxy-crylen (available in some countries) flame.
Fitting
The fitting process is based on the expansion (by an oxy-fuel flame) or contraction (by a cryogenic fluid) of a work piece in order to locate and fix it in a dedicated place.
Flame Cutting
Flame applications for cutting process use an oxy-fuel flame and straight oxygen as a cutting jet to separate the metal.
Laser Welding
The laser beam produced by a CO2 or a solid state YAG cavity is used for high penetration, high-speed welding processes, where mainstream processes can not deliver the required distortion and/or productivity.
Cryogrinding
You wish to… Enlarge the range of plastic and rubber materials to grind with high throughput in inert and safe conditions? Achieve the requested homogeneous particle size with the correct fineness? Preserve the physical and chemical characteristics of the grinded products from thermal damaging?
Foaming
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
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.
TIG Welding
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.)
Sintering
Sintered mechanical components are commonly produced in continuous furnaces, where the sintering operations are carried out in several, but strongly interconnected steps.
Plasma Cutting
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.
