High-Speed Stamping Press and Automatic Stacking Die for Zipper Fin Heat Sinks Production
What is a Zipper Fin Heat Sink?
In China, we usually refer to Zipper Fin Heat Sinks as heat dissipation modules, such as CPU cooling modules, LED heat dissipation fins, and CED miner lamp heat sinks. The advantage of Zipper Fin Heat Sinks is that they are easy to use and significantly increase the heat dissipation area. However, due to their unique structure, many people do not understand the production process of Zipper Fin Heat Sinks.
Today, we will provide a detailed explanation of the high-speed mass production of Zipper Fin Heat Sinks using stamping technology. Given the widespread applications and large consumption of Zipper Fin Heat Sinks, high-speed precision stamping with Samhoor Press is the best choice.
How Are Zipper Fin Heat Sinks Stamped?
It is well known that when we need to use a large number of thin fins in heat sinks, assembling each individual fin into a heat sink manually can be extremely difficult. In Chinese manufacturing solutions, this entire assembly process is automated within the stamping die.
The stamping die is designed in a progressive manner, consisting of multiple stamping steps to complete the high-speed stamping of Zipper Fin Heat Sinks. The precision of the die design is extremely high because each fin must fit together tightly. In stamping technology, we call this riveting.
Each stamped fin has several riveting points. These pieces are automatically stacked inside the die, eventually forming a complete product.
What Materials Are Used for Stamping Zipper Fin Heat Sinks?
The most commonly used materials for stamping Zipper Fin Heat Sinks are aluminum and copper, as they both possess excellent properties.
Aluminum
Aluminum is the most widely used material.
It is cost-effective and lightweight.
It is easy to cold-stamp and deform, making it highly suitable for high-speed stamping.
Its excellent thermal and physical properties make it the best choice for mass production.
The ease of deformation simplifies the design of high-speed stamping dies.
Copper
Copper has higher thermal conductivity than aluminum.
However, copper is heavy and expensive, which limits its widespread application in Zipper Fin Heat Sink stamping production.
Summary of Zipper Fin Heat Sink Stamping Characteristics
Advantages:
Simple mechanical locking structure with fewer processes.
The interface impedance caused by the connection between the Zipper Fin Heat Sink and the heat-absorbing base can be compensated.
Stable process quality, making it ideal for mass production.
Disadvantages:
To ensure assembly stability and alignment, the design requirements for individual Zipper Fin Heat Sink stamping dies are very high.
The YouTube video embedded on this page provides an excellent demonstration of the entire Zipper Fin Heat Sink stamping production line(SAH-65 high-speed stamping machine) . Many well-known brands have been working with Samhoor Press for years to ensure stable production.
As far as we know, one of the suppliers is a subsidiary of NVIDIA graphics cards, and their Zipper Fin Heat Sink stamping production alone has created astonishing wealth for the company.
We welcome your inquiries and hope that our real-world Zipper Fin Heat Sink stamping production cases can help solve any related challenges you may have.
