Push material through a controlled cross section.
Extrusion creates continuous profiles by forcing material through a shaped die, allowing long sections with consistent cross-sectional geometry in metals and plastics.
Understand the production sequence before selecting a supplier.
Material behavior, machine capability, tooling, geometry, inspection, finishing, and production volume all influence the final process plan.
Reliable production comes from controlling the variables.
Equipment alone does not define capability. Setup, tooling, material condition, maintenance, inspection, and operator knowledge influence the result.
Profile Geometry
Wall thickness, hollow sections, webs, radii, symmetry, and dimensional transitions influence die design and material flow.
Material Behavior
Aluminum alloys and thermoplastics have different temperature, pressure, cooling, shrinkage, and post-processing requirements.
Die & Process Control
Die condition, temperature, line speed, pressure, cooling, puller control, and calibration influence profile dimensions and surface quality.
Secondary Processing
Extrusions are often cut, machined, punched, drilled, anodized, painted, bonded, or assembled after the primary process.
Each process has its own physical logic.
These pages use new process-specific technical drawings rather than repeating the same decorative artwork.
Process mechanics.
Material movement, tooling, force, energy, and geometry determine how the part is created.
Quality controls.
Setup, material condition, machine calibration, inspection, and downstream operations determine repeatability.
Relevant external manufacturing resources.
These external resources are matched directly to the process topic.
Additional resources for aluminum extrusion profiles and manufacturers.
Extrusion is most effective when material flow, die geometry, temperature, cooling, line control, and downstream finishing are planned around the complete profile requirement.
