Extruded heat sinks are the most common heat sink used for thermal management today. They are manufactured by pushing hot aluminum billets through a steel die to produce the final shape.

The most common aluminum alloy is 6063-T5. When the material is extruded, the initial sticks are 30-40 feet in length and are very soft. The material is stretched by grabbing both ends to produce a straight stick.

After stretching, the material can be either air or over aged depending upon the required final hardness of the material. After the aging process, the material is cut to the final length and any final fabrication (holes, Tapping, pockets, or other secondary machining) can be done.

Hongwei Tech customizes various stamping heat sinks for power modules, adapters, chargers, etc.

A precision machined Heatsink is an ideal choice for smaller production requirements. The CNC Precision machining allows for cost effective, rapid production of quality heat sinks with minimal lead time. This process allows for the creation of complex geometric shapes and intricate details.

The advanced CNC machining technology offers several advantages, including high accuracy & precision, the ability to customize designs, and suitability for small to medium volume production.

The stamped are manufacture from metal. Stamping is the manufacturing process of applying extreme pressure to a piece of aluminum Consequently, it produces fins of the desired height, thickness, shape, and holes.This type of heat sinks is often recommended for low-power aplicatins.

Some of the benefits include :
✅Ideal for low Power ApplicationsLow cost
✅10mm - 50mm height
✅Lightweight
✅Various mounting methods (solder, clip, tape)

The CNC machining is an essential process for a precise and high quality extruded heat sink manufacturing. These machines perform precise cuts, cross-cutting, drilling, tapping, producing heat sink extrusions with optimal surface area for efficient heat dissipation.

The CNC machining is highly automated, which allows for the production of bulk aluminum extruded heat sink extrusions that are uniform in size, shape and design. This level of conformance ensures compatibility with electronic equipment and reduces the chance of defects during installation.

A heat sink is a component designed to enhance the heat dissipation from an electronic device. Generally, , , and ICs are the in switch power supplies that need & attached to maintain a safe temperature. Usually a heat sink is composed of a base plate and .

A heat sink is a heat exchanger that enables the transfer of heat generated by a device to surrounding media of lower temperature. By dissipating heat away from the device, its main function is to balance said device’s temperature at optimum levels for it to function as desired.

Traditionally, thermal management has taken the form of extruded, forged or die-casted heat sinks connected to the heat-generating electronics. However, the accelerating growth of many different types of electronic devices, the rise of more powerful microelectronics, and the push toward smaller, more compact designs are making it much more difficult to accommodate the bulky size and weight of these conventional heat sink designs.

The Stamping heatsink plates, supports and fins can be customized, allowing for direct integration with the case, pcb base or component. Heat Sink dimensions can be scaled upwards and even significantly downwards by leveraging high-precision stamping techniques.

After pre-shaping the fins and defining their contours in the stamping process, bending is applied. The fins, tailored unique to the end application while featuring true 3D-design and alignment, are then joined to the PCB & electronic devices. This can be done in a number of ways — by use of welding or mechanical joining methods.

Aluminum heat sinks are preferred in switching power supplies due to their excellent thermal conductivity, lightweight nature, cost-effectiveness, corrosion resistance, ease of manufacturing, and good mechanical properties.
