Product Description

Custom Sharp Aluminum Extrusions are aluminum profile products formed through high-precision die extrusion, renowned for their sharp edges, flat surfaces, and high customizability. These profiles not only possess the lightweight, corrosion-resistant, and high-strength characteristics of aluminum but also feature sharp-angle designs and precise tolerance control, making them suitable for fields with extremely high demands for structural accuracy and appearance. Examples include high-end mechanical equipment, precision instrument frames, industrial automation components, building curtain wall systems, and modern furniture design.

Common Alloys and Metallurgical Composition

The selection of alloys for custom sharp aluminum extrusions needs to balance strength, extrudability, and surface treatment effects. Below are commonly used alloys and their characteristics:

Customizable Parameters and Classifications

Custom sharp aluminum extrusions offer flexible customization in the following dimensions:

1. Cross-Section Shape Customization

• Standard Sharp-Angle Profiles: Right-angle, trapezoidal, polygonal, and other regular cross-sections.
• Complex Irregular Cross-Sections: Functional designs with grooves, snap-fits, heat sinks, etc.
• Hollow/Solid Structures: Selected based on load-bearing requirements.

2. Dimensions and Tolerance Control

• Outer Dimension Range: 10mm ~ 500mm
• Wall Thickness Range: 0.8mm ~ 15mm
• Tolerance Grades:
• Standard Grade: ±0.3mm
• Precision Grade: ±0.1mm
• Ultra-High Precision Grade: ±0.05mm (requires special dies)

3. Surface Finish Customization

• Mechanical Finishing: Polishing, brushing, sandblasting.
• Chemical Treatment: Anodizing (custom colors available), electrophoretic coating.
• Coating Treatment: Powder coating, fluorocarbon coating, Teflon coating.

4. Functional Customization

• Reinforcing Rib Design: Enhances local strength.
• Pre-set Threaded Holes/Mounting Slots: Reduces secondary machining.
• Optimized Heat Dissipation Structures: For electronic device housings.
  

  

Standards and Specifications

Production follows standards such as ASTM B221, EN 755, GB/T 6892, and supports customization based on customer drawings. Material certifications (RoHS, REACH), mechanical property reports, and dimensional inspection reports are provided.

Manufacturing Process

1. Die Design and Manufacturing: Uses H13 die steel with CNC precision machining. Supports rapid die development (7-15 days).
2. Hot Extrusion Forming: Heated to 450-500°C, extruded through the die to form the sharp-angle cross-section.
3. Cooling and Straightening: Online water or air cooling ensures dimensional stability.
4. Aging Treatment: T5/T6 heat treatment enhances mechanical properties.
5. Secondary Processing: Cutting, drilling, tapping, surface finishing, etc.
   

   

Typical Applications

• Industrial: Automation equipment rails, robotic arm frames, conveyor frames.
• Architectural: Curtain wall mullions, window/door profiles, decorative trims.
• Electronics & Electrical: Heat sink housings, chassis frames, instrument brackets.
• Transportation: Vehicle structural parts, marine interiors, rail transit components.
• Consumer Products: High-end furniture, display racks, sports equipment.

Procurement and Customization Process

1. Requirement Confirmation: Provide drawings or 3D models, indicating critical dimensions and tolerances.
2. Solution Design: Engineers assess process feasibility and recommend alloys and treatment options.
3. Die Manufacturing: Sign a die agreement (costs can be amortized over the order).
4. Sample Approval: Provide 3-5 samples for testing and validation.
5. Mass Production: Proceed with production and quality inspection per order requirements.
6. Packaging & Delivery: Anti-scratch packaging, global logistics support.

Technical Advantages

• Edge Sharpness: High-precision dies ensure edge radius (R) ≤ 0.5mm.
• Dimensional Consistency: Online inspection systems control tolerances with CPK ≥ 1.33.
• Quick Response: Supports low-volume customization (minimum order quantity from 100kg).
• One-Stop Service: Provides end-to-end solutions from die design to surface finishing.
