Custom Aluminum Skived Fin Heat Sink Aluminum Cooling Fin

Custom CNC machined aluminum skived fin heat sinks engineered for high-performance electronics cooling. As a professional aluminum manufacturer, we deliver skived fin heatsinks with thin, dense, integrated fins and excellent thermal conductivity. Custom sizes, fin geometries, and surface finishes are available to match your exact thermal management requirements.

Our skived fin heat sinks are manufactured in our own factory from high thermal conductivity 6000-series aluminum. The skived fin process produces thin, dense fins that are integral to the base material — eliminating bonding gaps and delivering superior heat dissipation for demanding electronic equipment. We support fully customized dimensions, surface treatments, and CNC precision machining. MetalPlus supplies reliable skived fin heat sinks for industrial electronics, power modules, amplifiers, and other thermal management projects. Contact us with your drawings for a quotation.

Our company employs more than 600 staff, including 50 R&D and structural design personnel, enabling us to prepare initial design drawings and heat sink specifications within the shortest possible time. Once the design is signed off, quotation and actual lead time are confirmed to the client.

We then move to the sample stage: MetalPlus extrudes the profiles and CNC machines a sample for testing. Once approved, the prototype is sent to the client. After prototype confirmation, production proceeds. This is the most cost-effective customization method for achieving high heat sink performance.

Anyone familiar with electronic products knows that heat dissipation is a critical concern in devices such as graphics cards, CPUs, and chassis power supplies — all of which use aluminum alloy electronic radiators. These represent only the everyday consumer applications.

Beyond consumer electronics, many industrial high-power devices rely on electronic radiators. Key applications for high-power electronic heat sinks include: audio equipment, UPS power supplies, EPS power supplies, inverters, transformers, monocrystalline and polycrystalline silicon, battery packs, new energy electronic controllers, charging piles, inverter power supplies, switching power supplies, IP power supplies, welding machines, communication transmitters, base stations, control cabinets, power regulators, and thyristors.

Equipped with 44 aluminum extrusion lines, MetalPlus produces commercial and industrial aluminum profiles with a maximum outer diameter of 350 mm. All lines feature PLC control systems and precision molds. The largest extruder in the factory is a 6,800-ton unit, used for industrial profiles in various shapes with a maximum diameter of 600 mm — allowing us to satisfy the diverse requirements of our customers. Products include radiators, industrial fan blades, motor enclosures, solar cell frames, doors, and windows.

MetalPlus can produce custom molds according to customer requirements and has the ability and experience to manufacture aluminum profiles with complex structures. Our in-house R&D team provides reasonable suggestions to help customers create superior products at affordable prices.

Anodizing forms a layer of aluminum oxide on the surface of aluminum alloy products when they are placed in an electrolyte solution and an electrical current is applied. Anodized aluminum profiles feature improved corrosion resistance, allowing the surface to withstand various weather conditions. The aluminum oxide layer also increases hardness and wear resistance. MetalPlus operates 6 anodizing production lines. Profiles processed in our lines feature uniform oxide film thickness and color for a beautiful appearance. Available colors include silver, black, gold, champagne, and imitation steel; other colors can be customized upon request.

All anodized products are inspected by highly trained professional inspectors. Defective products that cannot be re-processed are directly scrapped. Products with uneven color are de-coated and re-anodized until they meet requirements, ensuring no color difference between batches.

Our factory is equipped with 4 powder spraying lines, all using high-quality spray nozzles from Gema Switzerland. MetalPlus uses only safe, environmentally friendly paint with strong adhesive force and durable color retention.

MetalPlus is equipped with highly advanced machining equipment, and all fine machining processes are performed by technicians with extensive industry experience. Strict industrial standards are applied throughout production to ensure fine machining precision and product quality.

• 12 PRATIC machining centers for milling, drilling, and tapping of profiles from different angles — especially suitable for long profiles up to 6 meters, enabling machining of complex profiles with the simplest methods.
• Fully automatic cutting machines from Wegoma for precise cutting with automatic and continuous material feeding — low labor cost and high production efficiency, resulting in cutting prices significantly lower than industry peers.
• 30 punching machines with punching pressure from 50 to 100 tons, suitable for relatively thick profiles over 5 mm. Also 10 stretch bending / bending machines for bending profiles to arcs or different angles with high angular precision, plus 10 milling machines for machining different planes, bevels, or grooves to meet diverse customer requirements.

Finished products are packaged manually and prepared for delivery. MetalPlus follows strict warehouse management procedures: the finished product warehouse is divided into sections for specific products, all in-and-out transactions are recorded, and each product is examined before delivery.
