Extruded Small Aluminum Heat Sink CNC Machined Skived Fin Heat Sink for Electronic Chip 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 demanding electronic devices. As a professional aluminum manufacturer, we support fully customized dimensions, surface treatments, and precision CNC machining for industrial electronics, power modules, amplifiers, and other thermal management projects.

MetalPlus supplies reliable skived fin heat sinks with dense fin structures and excellent thermal conductivity. Custom sizes and designs are available — contact us with your drawings for a quotation.

With more than 600 employees and 50 R&D and structural design personnel, we can prepare an initial design drawing and heat sink specification within the shortest possible time. Once the design is signed off, the 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, full 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 critical concern in devices such as video cards, CPUs, and chassis power supplies — all of which use aluminum alloy electronic radiators. These represent only the everyday civil applications.

Many industrial high-power devices that receive less public attention also 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.

1. Based on customer requirements, we help design the appearance of extruded profiles, provide CAD drawings and 3D models for customer confirmation, customize molds, and extrude aluminum profiles that meet the customer's specifications.
2. For customers with design capabilities, our professional R&D team analyzes and optimizes the design based on the customer's drawings and our extrusion processing experience, using the most reasonable design to reduce production costs and improve product performance.
3. Our company adopts a "one-stop" service and production model covering product design, customized molds, aluminum bar melting and casting, extrusion profiling, precision machining, and surface treatment. We effectively control the alloy composition of raw materials and maintain product accuracy throughout production, delivering high-quality products.

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, satisfying 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. 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. 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, 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 accomplished by technicians with rich industry experience. Strict industrial standards are adopted during 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 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 highly precise machining angles.
• 10 milling machines for machining different planes, bevels, or grooves to satisfy diverse customer machining requirements.

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