1.Aluminum extrusion 

Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses. The extrusion process makes most of aluminum’s unique combination of physical characteristics.  Its malleability allows it to be easily machined and cast. Our cooperated manufacturer owns the biggest extrusion equipment(5500T & 7500T)  in Guangdong China. That enables us to have the capacity to manufacture extrusion the cross-sectional profile which dimension up to 650mm*400mm.

The process of aluminum extrusion consists of the following steps:

 After designing and creating the shape of the die, a cylindrical billet of aluminum alloy is heated. The die must be heated at the same time to avoid the aluminum alloy sucking the die because of suddenly cooling.

The aluminum billet is then transferred to a loader, Substantial pressure is applied to a dummy block using a ram, which pushes the aluminum billet into the container, forcing it through the die.

The quality of the first 2 to 10 meters long extrusion aluminum profile is not stable, we usually abandon it. The aluminum profile is the semi-finished product of the aluminum billet which is extruded through the mold by heating, and the mold is a high-precision tool designed according to the demand, which is used to extrude the profile product with the required specifications and section. The structure involved in the mold must meet the production requirements first and also conform to the physical and mechanical common sense to ensure that the products produced can achieve the performance used.

The extruded part passes onto a run-out table as an elongated piece that is now the same shape as the die opening. It is then pulled to the cooling table where fans cool the newly created aluminum extrusion. 

When the cooling is completed, the extruded aluminum is moved to a stretcher, for straightening and work hardening. The hardened extrusions are brought to the saw table and cut according to the required lengths. The final step is to treat the extrusions with heat in age ovens, which hardens the aluminum by speeding the aging process.

2.CNC milling, CNC machining

CNC milling is a certain type of CNC machining. Milling is a process that is quite similar to drilling or cutting, and milling can perform these processes for a variety of production needs. Milling utilizes a cylindrical cutting tool that can rotate in various directions.

In general, CNC mills are very efficient when it comes to prototyping, the short-run production of complex parts, and the fabrication of precision parts and components.

Advantages Of CNC Machining, Quick removal of large amounts of metal material,

Highly accurate and repeatable, Economical, Fast turnaround.

3.surface treatment

sand blasting 120 mesh, natural anodizing Sandblasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, shape a surface or remove surface contaminants.

After sandblasting, process the natural anodizing.

The chemical solution in the anodizing process and the stainless steel rivet will cause a chemical reaction to be dissolved, resulting in riveting defects. For the selection of the material, If use the titanium rivet, it would not cause a chemical reaction to be dissolved, but the raw material cost will be too high.

We use rivet riveting after anodizing, this will save the raw material cost meanwhile solve the problem of rivet chemical reaction to be dissolved

4.Rivet Riveting and Inspect of rivet riveting strength

There are 47 rivets in this heat sink, we use our technology to riveting all of them at a time, this also reduces the processing cost.

Requirement: Excellent heat dissipation performance, inspection of rivet riveting strength, does not allow any rivet loosening off within the ≦4.5N.M torque range.
