Key Benefits
- Tolerance down to +/-0.005 mm maintains tight fits on precision bores, bearing locations, and mating faces
- 4-axis and 5-axis CNC machining allows complex prismatic shapes to be machined in fewer setups
- Surface treatments including anodizing, sandblasting, and e-coating provide protection and correct surface finish
- Manufactured strictly to your drawing rather than selected from fixed catalogue configurations
- Processes follow certified quality management standards under ISO 9001 and ISO/TS 16949 / ISO/TS 16949
- Export packaging options include PP bags, cartons, crates, or custom boxes to prevent transit damage
Problems It Solves
- Eliminates fit issues on complex aluminium parts by maintaining tolerances down to +/-0.005 mm
- Avoids secondary processing delays by providing surface finishes like anodizing and sandblasting in-house
- Prevents part inaccuracies caused by multiple setups by utilizing 4-axis and 5-axis machining capabilities
- Solves drawing compliance issues by producing strictly custom parts rather than altering stock shapes

How It Is Made
- 1
Technical drawing review to confirm critical tolerances, datum faces, and finishing requirements
- 2
Raw aluminium billet preparation and inspection for dimensional and material consistency
- 3
4-axis and 5-axis CNC machining, milling, and surface grinding to drawing geometry
- 4
Secondary surface treatment application including anodizing, sandblasting, or plating
- 5
Final dimensional inspection and tolerance verification against drawing limits
- 6
Protective packaging in PP bags, cartons, crates, or boxes per order instructions
Quality Control
- Dimensional verification against drawing specifications holding tolerances down to +/-0.005 mm
- Surface finish and coating thickness inspection for anodized, painted, or plated surfaces
- Quality management systems audited and compliant with ISO 9001 and ISO/TS 16949 standards
- Material and RoHS compliance verification with documentation upon request
Customization Options
- Machined entirely to customer 2D prints and 3D CAD models rather than standard stock dimensions
- Wide selection of finishes including clear or color anodizing, sandblasting, and e-coating
- Choice of manufacturing processes across 4-axis, 5-axis milling, turning, and grinding
- Custom export packaging solutions tailored to prevent scratches and impact marks during shipping
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Die cast aluminium components | CNC machining holds +/-0.005 mm tolerances without tooling die costs, but unit cost is higher for extreme high volumes |
| Standard catalogue aluminium brackets | Custom CNC machining matches your mounting locations and geometry exactly, but requires drawing review and lead time |
| 3-axis machined parts | 4-axis and 5-axis machining handles complex angled faces and undercuts in fewer setups, though machine runtime is more complex |
Use Guide
- Provide a detailed 2D drawing with tolerances, datum references, and surface roughness requirements clearly marked
- Specify the desired aluminium grade and surface finish such as sandblasting or anodizing type
- Include 3D CAD files alongside 2D drawings to streamline 4-axis and 5-axis toolpath programming
- State packaging preferences such as individual PP bags or bulk crate packing for transport protection
- Confirm testing or certification paperwork needed prior to shipment
