Custom Extruded Aluminum Heat Sink High Density Fin Aluminum Skived Heatsink for Electronic IC Power Module Cooling

Our custom CNC-machined aluminum skived fin heat sinks are manufactured in-house from high thermal conductivity 6000-series aluminum. The skived fin process produces thin, dense, integrated fins without bonding gaps, delivering superior heat dissipation for electronic equipment, power modules, amplifiers, and other thermal management projects.

As a professional aluminum manufacturer, we supply high-performance skived fin heat sinks with fully customizable dimensions, surface treatments, and CNC precision machining. 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 a 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. Upon approval, the prototype is sent to the client. After prototype confirmation, production follows. 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 concern in devices such as video cards, CPUs, and chassis power supplies — these typically use aluminum alloy electronic radiators, which represent only the application of heat sinks in ordinary consumer products.

In addition, many industrial high-power devices that receive less attention are equally important and also rely on electronic radiators. Main applications of 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. The 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, satisfying diverse customer requirements. 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 produce 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 placed in an electrolyte solution and subjected to electrical current. Oxidized aluminum profiles feature improved corrosion resistance, allowing surfaces to withstand various weather conditions, while the aluminum oxide also increases hardness and wear resistance. MetalPlus operates 6 anodizing production lines. Profiles processed in our lines feature uniform oxidation film thickness and color for a beautiful appearance. Color options 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, and 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; the equipment enables machining of complex profiles with the simplest methods.
• Fully automatic cutting machines from Wegoma for precise cutting with automatic and continuous material feeding, featuring low labor cost and high production efficiency — resulting in cutting prices significantly lower than other enterprises in the industry.
• 30 punching machines with punching pressure ranging from 50 to 100 tons, suitable for relatively thick profiles over 5 mm; 10 stretch bending / bending machines for bending profiles to arcs or different angles with high precision; and 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 storing specific products, all in-and-out transactions are recorded, and each product is examined before delivery.
