Surface Treatment
Product Application
Crafted from premium 6000-series aluminum alloys, our profiles offer an exceptional balance of thermal conductivity (exceeding 180 W/m·K) and mechanical strength. The core of our design features an optimized multi-channel and fin architecture. This intricate geometry maximizes the surface area in contact with coolant or air, enabling rapid and uniform heat transfer away from sensitive components. Advanced simulation tools were employed to refine the fin density, thickness, and channel layout, ensuring peak thermal efficiency with minimal pressure drop for liquid cold plates or optimal airflow for heat sinks.
Beyond thermal performance, every parameter is tailored for the automotive environment. The profiles exhibit excellent corrosion resistance, crucial for long-term reliability under various operating conditions. Their high strength-to-weight ratio contributes directly to vehicle light weighting, aiding in extended driving range. We offer complete flexibility, providing custom extruded solutions—from simple shapes to complex, multi-void profiles—that integrate seamlessly into your module assembly. Value-added services include precision cutting, CNC machining, micro-grooving for sealants, and various surface treatments (anodizing, powder coating) to meet specific aesthetic and protective requirements.

Q2
Can the profiles be customized in terms of dimensions and shape?
Yes, we offer fully customized extrusion solutions. Profiles can be tailored in length (standard 6 m or custom), thickness (0.8–5.0 mm), cross-sectional shape (simple to complex multi-void designs), and color. Please share your drawings or requirements and our engineering team will assist you.
Q3
What surface treatment options are available?
We offer a wide range of surface treatments including Mill Finish, Powder Coating, Anodizing, Electrophoresis, Fluorocarbon Coating, and Wood Grain finishes. Custom colors are also available based on your specific requirements.
Q4
What is the minimum order quantity (MOQ) and lead time?
The minimum order quantity is 500 kg. For die development and sample testing, the lead time is 7–10 days. Mass production is typically completed within 15–30 days depending on the order volume and complexity.
Q5
What value-added processing services do you provide?
We provide comprehensive value-added services including Drilling, Milling, Cutting, Welding, Bending, Assembling, and CNC machining. This allows us to deliver ready-to-use components that meet your exact assembly requirements.
Q6
How are the aluminum profiles packaged for shipment?
Each profile is individually wrapped with a protective film to prevent surface damage. Profiles are then bundled together and wrapped with shrink plastic bags for secure outer packaging, ensuring the products arrive in perfect condition.
