Aluminum Extrusion
At SOMI Custom Parts, we deliver precision aluminum extrusion solutions for custom non-standard profiles. From simple solid bars to complex multi-void hollow shapes, every profile we produce is custom-manufactured — no standard sections, only tailored solutions. Our extrusion capabilities serve automotive, architectural, industrial, and consumer applications with tight tolerances and consistent quality. Comprehensive extrusion services for custom non-standard aluminum profiles across all major alloy series. In-house die design and engineering for solid, semi-hollow, and hollow profiles with optimized metal flow and uniform wall thickness. From simple angles and channels to complex multi-cavity shapes with integrated features like snap-fits, T-slots, and heat sinks. Extensive experience with 6000 series alloys (6061, 6063, 6082) plus 7000 series for high-strength applications. Complete post-extrusion services: cutting, CNC machining, punching, bending, welding, anodizing, powder coating, and assembly. Precision extrusion expertise combined with comprehensive secondary capabilities. Modern extrusion presses ranging from 800 to 3600 tons producing profiles up to 350mm width with tight dimensional tolerances. In-house solution heat treatment and artificial aging furnaces ensuring optimal T5 and T6 temper properties for every profile. Quality management system covering die design, billet inspection, extrusion process control, and final dimensional verification. In-house die shop with CNC and EDM capabilities — prototype dies in 1-2 weeks, production dies in 3-4 weeks. Clear and color anodizing, powder coating, electrophoretic coating, mechanical polishing, and brushed finish in-house. Flexible order quantities from prototype samples to full production runs, accommodating all project stages. A controlled process ensuring quality and precision at every production stage. Engineers design extrusion dies using FEM simulation for balanced metal flow and optimal profile geometry. Aluminum billets are preheated to 450-500°C in gas-fired furnaces for consistent extrusion temperature. Heated billet is pushed through the die under high pressure to form the profile shape continuously. Profiles are water-quenched for T5/T6 temper and stretched to straighten and relieve internal stresses. Precision cutting to length, dimensional verification, surface quality inspection, and packaging for shipment. Real applications across industries — every profile is a custom non-standard extrusion made to exact specs. Custom extruded aluminum rails, crash management systems, and decorative trim profiles for EV platforms and traditional automotive applications. Thermally broken window frame profiles, curtain wall mullions, handrails, and sunshade louvers with precision joinery features. T-slotted aluminum framing, conveyor guide rails, and modular machine bases with machined connection points for rapid assembly. Custom extruded heat sink profiles with optimized fin geometry for LED lighting, power electronics, and telecom equipment cooling.

Frequently Asked Questions About Aluminum Extrusion Services
What is the minimum order quantity for custom aluminum extrusion? Minimum orders typically range from 200-500kg for prototype and pilot runs, with production quantities starting from 2000kg per profile. We also offer split-die and multi-profile consolidation for smaller quantities across multiple designs.How much does an extrusion die cost? Die costs vary: solid profile dies from $800-1,500, semi-hollow dies from $1,200-2,500, and hollow dies with mandrels from $2,000-5,000. Die costs are typically amortized over the first production order.What aluminum alloys are best for extrusion? 6063 is most common for architectural profiles due to excellent surface finish. 6061 offers higher strength for structural uses. 6082 provides superior strength-to-weight for demanding industrial applications. We also work with 6005, 6060, and 7005 alloys.What surface finishes do you offer for extruded aluminum? Comprehensive finishing: mill finish, clear anodizing, color anodizing (gold, bronze, black), hard coat anodizing, powder coating (RAL colors), electrophoretic coating (ED), mechanical polishing, brushed finish, and sandblasting.What tolerances can you achieve for aluminum extrusion? Standard tolerances follow EN 755-9 or ASTM B221. Typical cross-section tolerance ±0.3-0.5mm, cut length ±0.5-2mm. Tighter tolerances available with precision dies and secondary machining on critical features.
