Our Custom CNC Aluminum Extrusion Service
We accept custom orders based on your CAD, DXF drawings, sketches or physical samples.
Custom die development for exclusive aluminum extrusion profiles
- CNC machining service: milling, drilling, tapping, notching, cutting, chamfering, hole position precision adjustment
- Alloy options: 6063-T5, 6061-T6, 6005, 6082 and other aluminum series
- Flexible MOQ: support small batch prototype testing and large-volume industrial production
- Adjustable tolerance: standard ±0.05mm, ultra-tight tolerance available for critical functional features upon request
- Multiple surface treatments: anodizing, powder coating, fluorocarbon coating, wood grain transfer, sandblasting
Extra buying point added: We provide pre-production sample confirmation before mass run, so you can verify dimension, surface quality and assembly performance in advance.
Strict In-House Quality Control
Quality control runs through every procedure of your custom CNC aluminum extrusion.
- Raw aluminum ingot incoming inspection to guarantee alloy composition
- First article inspection after extrusion and CNC setup
- Dimensional check with calipers, height gauges and CMM for precision-critical parts
- Surface defect check for scratches, burrs and coating uniformity
- Random sampling before packing; full inspection for high-spec industrial orders All our products comply with CE, TUV, SGS, RoHS, ISO and KS standards. Inspection reports can be provided together with shipment documents.
Packaging & Shipment Protection
Machined aluminum profiles with CNC features have sharp edges and precise threaded holes, so we adopt protective packaging to avoid scratching, deformation and thread damage in transit.
- Individual PE foam wrapping for each CNC machined component
- Interlayer foam padding inside export cartons or plywood cases
- Reinforced strapping for long extruded bars
- Mark drawings, part numbers and quantity clearly on outer packages
- Flexible shipping terms: FOB, CIF, DDP, sea freight, air freight for urgent prototype orders

FAQ
Q1: Can you make custom CNC aluminum extrusion from my drawing?
A: Yes. Send CAD/DXF/PDF files, alloy grade, tolerance, surface finish and estimated quantity. Our engineer will evaluate and send quotation within 48 hours.
Q2: What is the lead time for CNC machined aluminum extrusion samples?
A: Existing mold: 7–12 working days. New die development: 15–25 working days after die approval.
Q3: Can you guarantee tight tolerance for CNC holes and threads?
A: Standard tolerance ±0.05mm. We can achieve tighter tolerance for key features; we will confirm capability before quotation.
Q4: Do you support third-party inspection?
A: Sure, we welcome third-party inspection at our factory before delivery.
