Need custom aluminum extrusions with tight tolerances? Chiheng provides custom extruded aluminum profiles for industrial and OEM applications — fast turnaround, low MOQ, DFM support.
Precision-engineered custom aluminum profiles for industrial, OEM, and B2B applications. From extrusion design to secondary machining — all under one roof.
Custom aluminum extrusions are profiles shaped by forcing aluminum alloy through a precision-engineered die, producing cross-sections tailored to your exact specifications. Unlike standard off-the-shelf profiles, custom extrusions are designed from the ground up to fit your product — whether you need a structural frame, a thermal management component, or a complex multi-void industrial shape.
At Chiheng, we manage the entire process in-house: from DFM review and die design, through extrusion and CNC post-machining, to surface finishing and quality inspection. MOQ starts at just 1 piece, making us the right partner for prototypes, small-batch production, and full-scale OEM supply alike.
We manufacture a wide range of custom aluminium extrusion profiles across industries. Whether your design is a simple angle or a complex hollow section, our tooling team will engineer a die to match.
Single-piece cross-sections with no internal voids. Commonly used for structural bars, brackets, and mounting rails. Ideal where high strength-to-weight ratio matters.
Single or multi-void tubular sections. Used in framing systems, enclosures, and fluid-carrying components. We support thin-wall designs down to 0.8 mm wall thickness.
Modular T-slot profiles compatible with standard or custom fastener systems. Widely used in automation frames, workbenches, and machine guarding.
Fin-array profiles designed for passive thermal management. We work with your thermal specifications to optimize fin pitch, height, and base thickness.
I-beams, U-channels, L-angles, Z-sections, and fully bespoke asymmetric profiles. If you have a drawing, we can extrude it.
Complex profiles with multiple internal chambers or very thin walls. Used in aerospace-adjacent, electronics, and lightweight structural applications.
Why Chiheng
MOQ of 1 — prototype to production
Validate your profile design with a single piece before committing to volume. Prototype orders receive the same engineering rigor as mass production runs.
Custom extrusion design support
Submit DXF, DWG, STEP, or PDF. Our engineers review every submission for manufacturability and return DFM feedback before tooling begins — saving time and rework costs.
In-house CNC secondary machining
Milling, turning, drilling, and tapping — all in the same facility. Shorter lead times and no supplier handoffs between extrusion and machined components.
Surface finishing under one roof
Anodizing, powder coating, brushing, and sandblasting are all available in-house. We deliver finished, ready-to-assemble parts — not just raw extrusions.
Tight dimensional tolerances
Cross-sectional tolerances to ±0.1mm on standard profiles, with tighter tolerances achievable on request. Every batch ships with a full dimensional inspection report.
Fast sample turnaround
From die approval to first sample in 7 days. Production lead time 15 days depending on profile complexity and order volume.

Step 1 — Submit Your Drawing Upload your cross-section drawing (DXF, DWG, STEP, or PDF). Our engineering team reviews wall thickness, corner radii, die complexity, and material selection. We return quotation and feedback within 24 hours.
Step 2 — Die Design & Tooling Once the design is approved, we design and manufacture the extrusion die in-house. Die lead time is [X] days. You own your die — it is stored at our facility for repeat orders at no additional charge.
Step 3 — Extrusion & Post-Processing We run your profile on the appropriate press tonnage for the alloy and cross-section. After extrusion, parts proceed directly to any specified secondary operations: CNC machining, cutting to length, drilling, tapping, or surface finishing.
Step 4 — Quality Inspection & Shipping Every order is dimensionally inspected against your drawing before dispatch. We provide a full inspection report with each shipment. Parts are packed to prevent transit damage and shipped via your preferred freight method.
Custom extruded aluminum profiles from Chiheng are used across a broad range of industrial and OEM applications:
How much do custom aluminum extrusions cost?
Cost depends on four main factors: cross-section complexity (which determines die cost), alloy selection, order quantity, and any secondary operations required. One-time die costs typically depending on profile complexity. Per-piece extrusion costs decrease significantly with volume. Submit your drawing for an itemized quote — we respond within 6 hours.
What is the minimum order quantity?
MOQ is 1 piece. We support single-piece prototype orders through to full production volumes without requiring you to re-qualify suppliers as you scale.
How long does it take to produce a custom die?
Die fabrication takes 15 days from drawing approval. Rush tooling is available on request.
Can you machine the profiles after extrusion?
Yes. We offer in-house CNC milling, turning, drilling, and tapping as secondary operations. This allows us to deliver fully machined, ready-to-assemble parts rather than raw profiles.
Do you offer custom metal extrusion services for materials other than aluminum?
Our primary capability is aluminum extrusion. For other metals, we offer CNC machining, die casting, and sheet metal fabrication. Contact us to discuss your full bill of materials.
What file formats do you accept for drawings?
