Thermal Management

Fin spacing and height are designed to support airflow and improve passive heat dissipation within standard extrusion requirements.

Thermal performance is evaluated using SolidWorks Flow Simulation to identify potential heat concentration areas under standard operating conditions.

Under continuous load, typical temperature rise remains within ΔT ≤ 28°C, depending on installation and airflow conditions.

Surface flatness is monitored during production to support consistent PCB contact and effective thermal transfer.

Custom Fabrication & CNC Capabilities

Custom Fabrication
Extrusion Processing: In-house production covers billet heating, profile extrusion, and straightness correction.

Length Sawing: Precision cutting equipment supports batch production with custom length requirements.

Surface Treatment: Anodizing, electro-coating, and sandblasting options are available based on application requirements.

CNC Capabilities
Multi-axis CNC milling centers support machining operations including pocket milling and slotting.

High-speed CNC systems achieve repeatable dimensional tolerances within ±0.05 mm.

CNC-controlled drilling and tapping support consistent hole positioning and thread quality across production batches.

Quality Control & Compliance

ISO 9001:2015 Management System: Factory operations comply with documented protocols for process auditing.

RoHS & REACH Compliance: X-ray fluorescence (XRF) testing verifies hazardous substance limits across material batches.

Spectrochemical Alloy Validation: Optical emission spectrometry is used to verify alloy composition in 6063 aluminum billets.

Coordinate Measuring Machine Inspection: CMM inspection is used to verify profile dimensions against approved drawings.

Webster Hardness Testing: Webster hardness testing is performed to verify mechanical properties after aging treatment.

Full Critical Dimension Gaging: Critical dimensions are checked using dedicated gauges during production inspection.

Supply Chain & MOQ Policy

Stock Sample Availability: Existing profile samples can be provided for preliminary fit and application evaluation.

MOQ Policy: Standard profiles support small trial orders, while custom dies require higher order quantities.

Sample Lead Time: Custom tooling and sample production typically require about 14 working days.

Multi-Layer Scratch Protection: Individual extrusions are wrapped in PE foam film to prevent surface friction damage.

Reinforced Export Packaging: Finished batches are packed into bundled wooden crates to minimize linear bending risks.

FAQ

Q: Can you match custom RAL colors for powder coating finishes?

A: Yes, we provide architectural powder coating matched to designated RAL color codes based on client project specifications.

Q: How do you prevent long aluminum profiles from bending during maritime transit?

A: We utilize reinforced wooden crates with internal steel strapping to maintain alignment and eliminate linear bending risks.

Q: How long can a custom extrusion die typically be used?

A: Standard H13 steel dies can typically support several thousand kilograms of production before maintenance is required.

Q: Do you accept third-party quality inspections at your factory before shipment?

A: We regularly coordinate with independent agencies like SGS or TÜV for pre-shipment quality and dimensional auditing.
