Custom extruded aluminum parts solve a specific challenge: when you need a custom profile shape that off-the-shelf stock can't provide, and you need it manufactured consistently across hundreds or thousands of units. Extruded products are the standard choice for structural frames, thermal management systems, custom enclosures, and specialized brackets across automotive, industrial equipment, construction, and electronics applications.
China has become the natural destination for extruded products manufacturing because the infrastructure is already in place. Many suppliers handle the complete job, extrusion, CNC machining, drilling, anodizing, so you're not coordinating multiple vendors. For quoting, you can contact extrusion factories directly, or you can use Haizol to run an RFQ. An RFQ is a request for quotation that includes CAD files plus requirements such as alloy, tolerances, quantities, and certification needs. Haizol routes RFQs to verified factories, meaning suppliers that have passed Haizol’s qualification process and are authorised to quote through the platform, which reduces the risk of unqualified shops bidding on work they cannot deliver.
Haizol also supports NDA controls for drawings, and it offers three NDA options, including no NDA, a platform standard digital NDA, or a buyer-uploaded NDA that suppliers must sign before file access. Haizol assigns a dedicated account manager to support RFQ clarification, supplier coordination, and issue handling through production. For related needs, explore CNC machined parts from verified factories on Haizol. Haizol's network also covers anodized parts.
What Lead Times Should I Expect for Custom Extrusion Projects?
Die fabrication takes 2–4 weeks. Production runs 2–4 weeks depending on volume and complexity. Add 1–2 weeks per secondary operation (cutting, drilling, finishing). Total: 6–10 weeks from RFQ to finished extruded products. Standard profiles using existing dies ship in 2–3 weeks. Rush production available at select facilities.
What Tolerances Can Aluminum Extrusion Suppliers Actually Hold?
Standard tolerances: ±0.10–0.20mm linear dimensions, ±10% wall thickness, ±1° angles. Precision capability: ±0.05mm on critical features with CMM inspection. Specify which dimensions are critical vs flexible, factories will quote accordingly for your extruded aluminum parts.
How Are My Custom Profile Designs Protected on Haizol?
Haizol offers three NDA levels: no NDA required, platform-standard digital NDA, or your custom uploaded NDA. All drawings protected before supplier access. All communication stays within the platform for complete traceability of your extruded products.
What Secondary Operations and Finishing Options Are Available?
Haizol-verified suppliers offer CNC machining, drilling, cutting, bending, deburring, anodizing, powder coating, and specialized finishes for extruded products. Source extrusion + secondary ops from one factory to eliminate coordination and speed up timelines. Specify all operations in your RFQ.
What Quality Certifications Should I Require for Extruded Parts?
Many factories on Haizol hold ISO 9001 for extruded aluminum parts. Industry-specific certifications available: IATF 16949 (automotive), AS9100 (aerospace), ISO 13485 (medical). Factory profiles display certifications; filter by your industry requirements during quotation.
