Manufacturing Process
Friction stir welding utilizes frictional heat as the welding heat source.
The welding process is completed by a special form of stirring head with a probe and shaft shoulder, as shown in the attached figure.
First, rotate the stirring head at high speed and insert the probe into the seam between the workpiece to be welded. Friction rapidly generates heat, and the metal temperature around the probe increases, forming a thermoplastic metal layer. The probe moves down to make the shoulder of the shaft closely contact the working surface, which is close to the surface of the workpiece. When the stirring head moves along the seam of the workpiece, the thermoplastic metal in front of it continuously flows towards the back, and through mutual diffusion and recrystallization, the workpiece is firmly bonded together to form a weld.

Manufacturing Process
A typical heat pipe consists of a copper tube in which the inner walls are lined with a wick structure.
The heat pipe is charged with de-ionized water and then vacuum sealed. This gives the water a lower boiling point.
When the heat pipe is heated at one end, the working fluid evaporates from liquid to vapor (phase change).
The vapor travels through the hollow core of the heat pipe to the other end of the heat pipe, where heat energy is being removed by a heat sink or other means. Here, the vapor condenses back to liquid and releases heat at the same time.
The liquid then travels back to the original end of the heat pipe via the wick by capillary action.

Manufacturing Process
Skived fins are achieved by a knife tool that literally shaves fins up from an extruded aluminum or copper base. This process of slicing and then standing the fins up one at a time can create an extremely high fin-to-gap aspect ratio. The top of the fins are then cut to maintain a uniform height. This increased surface area drastically improves the thermal performance in forced airflow environments.

Manufacturing Process
A billet of aluminum is heated to temperatures in excess of 900°F.
Next, the billet is pressed and drawn through a die of the desired cross section by a rod with up to 22 tons of force.
The extrusion is then manually pulled through the opposite end and cooled.
In the final stage, the extrusion is cut to the requested length.
At this point secondary processes are then performed.

We use 3-axis milling and 5-axis indexed milling processes to manufacture complex 3D structures with high precision. We have dozens of such high-end CNC machines, which allow us to deliver reliable on-demand production parts (quantity from 1 up to a few thousand) with a much shorter lead time and lower price.
Manufacturing Process
Bonded fin heat sinks are manufactured using an assembly process that involves bonding a layer of thin metal fins to a base or substrate. The following is the general process for manufacturing bonded fin heat sinks:
Preparation: The base and fins are typically made from aluminum or copper and are carefully cleaned to ensure that the bonding process will be successful.
Bonding: The fins are then bonded to the base using an adhesive material, such as epoxy or a thermal transfer compound. The adhesive material is typically applied to the base in a uniform manner, and then the fins are placed on top and pressure is applied to ensure a strong bond.
Curing: The adhesive material is then cured, usually by heat , to create a permanent bond between the fins and the base.
Assembly: If the heat sink requires additional components, such as mounting hardware or interface material these are attached at this stage.
This process can be automated for high volume production or performed manually for smaller runs. The choice of materials, bonding method, and assembly process will vary based on the specific requirements of each application, but the general process remains largely the same.
