Experts in aluminum Hydroforming

For more than 30 years JiouJiou has been serving customers in Asia, Europe and the USA.

With a long history and proven know-how in engineering we realize our customers' designs from simple butted tubes to complex shapes.

Based on our consulting and understanding of our technical and engineering abilities as well as production processes you are able to understand the possibilities offered for the design of your products but also will understand the technical limits.

Attention to Detail

Details that matter. A hydroformed tube is at the beginning of a long process along the supply chain: welding/brazing, painting/anodizing, assembly. All steps require attention to detail to obtain an accurate finishing and in order to guarantee a smooth production process for the next step.


Sharp edges not only can harm workers during the handling of the product but also damage cables when they are integrated. We manufacture the tubes in a quality that our customers expect.

Thickness distribution

Together with our customers, we develop cost-effective solutions that meet and pass required strength and fatigue testing with optimal material use.

Surface finishing

Every single tube is visually inspected to ensure a defect-free surface finishing. A thorough inspection process avoids rework before painting or anodizing.
