The international community of composite materials met at JEC World 2022, the important event held in Paris from 3rd to 5th May, for three days of innovations and sharing of knowledge and experiences.

ST BlowMoulding has been designing and manufacturing blow moulding machines for technical applications since 1980 and, thanks to continuous developments, it has become the world leader of extrusion-blow moulding technology.

The company participated at this important exhibition presenting the benefits offered by blow moulding machines for the production of CPV liners (LPG - CNG - CHG).

Nowadays, the automotive companies are making big investments in Hydrogen technology (fuel cell and storage tanks) for passenger cars and commercial vehicles like trucks and buses.

Reducing to zero the Green House Gases emission is therefore the challenge for the automotive industry of the future and fuel cells vehicles powered by Hydrogen will be the final solution for the next decades.

Generally, both CNG and CHG require high pressure to ensure a reasonable driving range and Composite Pressure Vessels, plastic liners wrapped by carbon fibers, provide both the mechanical strength to withstand the internal pressure and the lightness required for the installation on vehicles.

Composite Pressure Vessels are also the perfect solution for the LPG cylinders as they are lighter and safer than the common steel cylinders.

Extrusion-blow moulding is the most efficient technology to get complete liners for composite pressure vessels in a single process: much faster than rotational moulding, much simpler than injection moulding and welding.

ST BlowMoulding is working on this application since long time and developed a wide experience with its customers in Europe with specific machines to properly plastify special PA grades and to produce different sizes of liners.

Its blow moulding machines can consistently produce PA liners for CHG tanks proven to match the Hydrogen industry requirements, in terms of safety, quality and durability, avoiding failures, machine downtimes and expensive replacements/repairs.

At JEC World, ST BlowMoulding hosted at its booth MTS-Moulage Technique Soufflage, expert company in the extrusion blow moulding of technical plastic parts, which is currently adopting ST BlowMoulding machines to produce modified PA liners for Hydrogen tanks.

The collaboration with this important French partner provided a mutual growth thanks to the exchange of skills, knowledge and technologies.

The balance of participation at the fair is decidedly positive with a good attendance of visitors.

ST BlowMoulding is very satisfied with the contacts made at its booth which allowed a fruitful and interesting exchange of knowledge of great professional value.
