Aluminum Extrusion: From Industrial Frameworks to Core Forming Technology for New Energy Vehicles

In the field of metal processing, aluminum extrusion has emerged as a highly efficient and flexible forming process, widely applied across sectors ranging from building windows and doors to new energy vehicle battery trays, from industrial automation frameworks to consumer electronics enclosures. Aluminum alloys, with their low density, excellent corrosion resistance, superior thermal and electrical conductivity, and high recyclability, have become one of the most extensively used non-ferrous metals in modern manufacturing. Ningbo Allytech Imp. & Exp. Co., Ltd. leverages its integrated manufacturing capabilities in aluminum extrusion and subsequent precision CNC machining to deliver one-stop aluminum product solutions from profile forming to finished part delivery to global clients.

Overview of Aluminum Extrusion Process

Aluminum extrusion is a forming process in which heated aluminum billets are pushed through a die of specific geometry using an extrusion press, producing continuous profiles with fixed cross-sectional shapes. The key advantages of this process include:

• Flexible cross-section design: Capable of producing profiles with virtually any cross-sectional geometry to meet diverse functional and aesthetic requirements

• High material utilization: Near-net shape forming minimizes material waste in subsequent processing

• Superior production efficiency: Ideal for high-volume continuous production with significant economies of scale

• Excellent mechanical properties: The metal grain flow aligns with the profile direction during extrusion, resulting in strength superior to castings

Allytech’s 5,000-10,000 sqm facility in Haishu District, Ningbo, is equipped with 3 dedicated production lines covering the complete process from billet heating, extrusion, online quenching, to artificial aging treatment.

Key Application Areas

1. New Energy Vehicles and Transportation
Lightweighting is a critical pathway for improving the driving range of new energy vehicles. Aluminum extrusions are widely used in battery pack frames, motor housing heat dissipation structures, crash beams, and sunroof guides. Allytech provides custom extrusion solutions for EV battery trays and structural components, helping clients achieve weight reduction targets.

2. Industrial Automation and Machinery
Automation equipment frames, conveyor tracks, robotic seventh axes, and workbench supports extensively utilize aluminum structural profiles. The modular design characteristics of aluminum extrusions make them the material of choice for industrial framing systems.

3. Construction and Home Applications
In windows, curtain walls, sunroom structures, interior partitions, and bathroom hardware, aluminum extrusions dominate due to their weather resistance and diverse surface finishing options.

4. Electronics and Communication Equipment
Heat sinks, chassis enclosures, LED lighting heat dissipation structures, and 5G base station housings — applications with high thermal management requirements — find aluminum extrusions ideal.

Full-Chain Services from Profile to Finished Part

Allytech offers not only aluminum extrusion processing but also integrated capabilities in CNC machining, stamping and sheet metal fabrication, and surface finishing. Clients can complete the entire workflow from profile extrusion to precision machining, from structural assembly to surface coating, through a single supplier, effectively reducing supply chain management costs. With a 5-10 person R&D and QC team, we provide DFM review support during the product development phase, ensuring design feasibility and cost controllability.
The value of aluminum extrusion processing lies not only in “forming” itself but also in helping clients achieve lightweighting, cost reduction, efficiency improvement, and product upgrades through appropriate material selection and process optimization. With aluminum extrusion at its core, complemented by CNC machining and surface finishing capabilities, Allytech is committed to delivering reliable, efficient aluminum product manufacturing services to global industrial clients.
