ALUMINUM EXTRUSION — HIGH-PRECISION PROFILES
Aluminum Extrusion ProfilesInternational Quality
Long-length aluminum profiles with consistent geometry and high dimensional precision — from extrusion die design through final surface finishing.
Why Choose ONTOPS for Aluminum Extrusion?
Beyond extrusion, we control the complete process: tooling, pressing, heat treatment, surface finishing and final inspection.
±0.05mm
Cross-section tolerance compliant with EN 755 and ASTM B221 for export profiles
0.3mm/m
Maximum straightness after extrusion and stretching for accurate production-line assembly
T5/T6 temper
Controlled aging increases yield strength by 40–60% over the as-extruded condition
<48h
Cross-section tolerance compliant with EN 755 and ASTM B221 for export profiles
Complex and Diverse Profiles
From basic profiles to complex multi-void sections, with custom dies engineered to your drawings.
Hollow · Multi-void · Custom section
Optimized T5/T6 Properties
Controlled aging achieves the specified temper, hardness, tensile strength and load capacity.
HB 70–100 · UTS up to 340 MPa
Precision and Straightness
Post-extrusion stretching, straightening and cutting maintain tight tolerances across the full profile length.
Straightness ≤ 0.3 mm/m · Length tol. ±2 mm
Premium Surface Quality
Strict process control minimizes die lines and creates an excellent base for anodizing, powder coating and PVDF.
Ra ≤ 0.8 µm · Anodize class AA15/AA20
RoHS · ASTM B221 · EN 755
Batch inspection · Mill certificate
Die lead time < 48h
Exports to EU · Japan · ASEAN
