- Alloy & Temper Review
- Machining & Finishing
From Heated Billet to Finished Profile
Extrusion forms a continuous cross-section through a shaped die. Cooling, straightening, temper development, and downstream work follow the chosen alloy and production route.
Voorbereiding van de staaf
Cut and heat the selected alloy billet for controlled flow through the die.
De extrusie
Form the approved solid, semi-hollow, or hollow cross-section.
Gecontroleerde koeling
Match cooling or quenching to the alloy, section, and required temper.
Straightening
Stretch and straighten suitable profiles to control bow, twist, and distortion.
Temper Development
Apply alloy-appropriate conditioning; age heat-treatable grades when specified.
Secundaire bewerkingen
Cut, machine, finish, and inspect the profile to the approved drawing.
Directe extrusie
The ram pushes the billet through a stationary die. This widely used route supports many custom solid and hollow profile geometries.
Indirecte extrusie
A die advances into the billet with reduced billet-to-container sliding friction. Suitability depends on the profile and available press setup.

Custom Extrusion Questions
Moet ik voor 6061 of 6063 kiezen?
6061 is often selected for structural requirements and secondary machining. 6063 is often preferred for extrudability, detailed profiles, and visible anodized appearance. The final choice also depends on temper, geometry, load, and finish.
Does a custom profile need a new die?
A new cross-section normally needs a dedicated die. Cost depends on section size, solid or hollow construction, die complexity, expected production, and correction requirements. Existing tooling can be reviewed where applicable.
When does custom extrusion become economical?
It is attractive when a repeated cross-section removes substantial machining, joining, or assembly work. Compare die cost, material yield, run quantity, finishing, and the complete delivered-part route.
How are thin walls and distortion controlled?
Review wall balance, radii, supported features, die design, alloy, cooling, stretching, and handling. Define acceptable straightness, twist, and flatness on the drawing instead of relying on a single general size tolerance.
What determines practical profile length?
Press runout, cooling, straightening, temper development, handling, shipping, and final cutting determine the usable length. State the delivered cut length and end requirements in the quotation package.
Can the extrusion be machined and finished afterward?
Yes, subject to review of datums, machining allowance, alloy condition, workholding, and finish sequence. Identify critical machined features, coating allowances, and surfaces requiring masking.
