    Machining, forming and fabrication of aluminium extrusions

    Hydro machines, forms and fabricates extruded aluminium into production-ready parts, using CNC machining, punching, bending, hydroforming, welding and finishing.

    Forming aluminium extrusions for complex geometry  

    Aluminium's formability makes it possible to create complex parts without adding weight. We use forming methods including hot gas forming, hydroforming, stretch forming and bending, supported by simulation and testing, to achieve high dimensional accuracy.

    Mechanical joints vs welding

    Extruded aluminium profiles can be designed for efficient mechanical joining. Mechanical joints are often simple to assemble, some can even be completed by the end user, and allow surface finishing on long lengths before cutting, reducing cost.

    CNC machining and punching  

    Aluminium profiles can be designed to need minimal machining after extrusion, but some processing is often required. Machining aluminium is relatively inexpensive: its malleability keeps tooling costs competitive, and higher cutting speeds than steel keep machining costs low. Punching complements machining for large series, covering hole-cutting, cutting out blanks and cutting off lengths quickly and cost-effectively. 

    Hydroforming and bending

    Hydroforming is a process that uses internal fluid pressure to form an aluminium tube into a complex three-dimensional shape in a single operation. We bend profiles and tubes to a defined radius, using stretch bending, roller bending, press bending or draw bending. Draw bending is the most widely used method, offering tight radii and good repeatability.

    Added-value machining: from profile to part  

    When you order extruded profiles from Hydro, you can add value with machining operations such as sawing, turning, drilling, milling and threading, as well as deburring and punching. Punching can include hole-cutting, cutting out blanks and cutting off lengths.

    Beyond extrusion, we offer finishing, joining, assembly and logistics services so you receive parts ready for your production line or project.  

    Lacquering

    laquage

    Lacquering adds durable colour and surface protection to aluminium profiles and parts, with resistance to UV, corrosion, impact and abrasion.

    Anodizing

    anodisation

    Anodizing is an electrolytic surface treatment that hardens and protects the aluminium surface while giving a natural metallic feel. It resists corrosion and wear, with a range of colour tones available.  

    Crimping / Barrettage

    sertissage

    Crimping (barrettage) joins aluminium profiles with polyamide bars to create a thermal break, useful for building applications requiring improved thermal performance.

    Cut to length

    coupe

    We cut extruded aluminium profiles to length, from 5 mm pieces to lengths of up to 12 metres, to match your assembly or delivery needs.  

    Machining

    Our CNC machining capability, including 5-axis machining centres, handles parts from small automotive components to multi-metre building-industry profiles, and can multiply the functions integrated into a single profile.  

    Punching

    poinçonnage

    Punching is fast and cost-effective for large series production, using dedicated tooling for shearing and cutting.  

    TIG / MIG welding

    TIG/MIG welding

    6000-series aluminium alloys weld well using TIG or MIG processes, and extrusion design can integrate features that make welding easier.  

    FSW welding

    FSW welding

    Friction stir welding (FSW) joins aluminium by mixing the material with a rotating tool rather than melting it, giving a homogeneous, flush weld with reduced distortion and strong thermal performance.  

    Bending

    cintrage

    Bending method depends on bend radius, profile shape, appearance and production volume. We offer draw bending, stretch bending, roller bending, and press bending.  

    Mounting and assembly

    montage

    We can assemble your components before delivery, from gasket installation to crimped threaded inserts, so you receive a finished, ready-to-install product.  

    Kitting

    mise en kit

    We can prepare your parts in kits tailored to your specifications, including protective film, labelling, and screw-bag inclusion.  

    Storage

    stockage

    We can store your profiles under agreed conditions and release them according to your supply schedule.  

     

    Frequently asked questions

    Aluminium extrusions can be processed using a range of machining methods, including sawing, drilling, milling, turning, threading, deburring, and punching. These operations help transform a profile into a finished component ready for assembly.

    A metal-forming process that uses internal fluid pressure to press an aluminium tube outward into a die, producing a complex three-dimensional shape in one operation.

    Bending changes curvature along a tube's length; hydroforming reshapes a full three-dimensional geometry, including features bending cannot produce.

    Extruded aluminium profiles can be designed for efficient mechanical joining. Mechanical joints are often quick to assemble, may be completed by the end user, and can reduce costs by allowing surface finishing on long profile lengths before cutting.

    A wide range of aluminium profiles and tubes can be bent using methods such as stretch bending, roller bending, press bending, and draw bending, allowing manufacturers to achieve specific shapes and radii for different applications.

    Forming processes such as stretch forming and bending enable aluminium profiles to be shaped into complex geometries while maintaining low weight and high dimensional accuracy. Simulation and testing can also be used to help achieve the required specifications.
