Some Die Cast HeatSink Project

Die casting is a highly efficient manufacturing process that can produce parts with complex shapes. With die casting, heat sink fins can be incorporated into a frame, housing or enclosure, so heat can be transferred directly from the source to the environment without additional resistance.

Custom Die cast heatsinks are a practical means to cool different electronic components and devices. These include circuit boards, LED fixtures, automotive, communication and military electronics. With advanced die casting processes, larger heat sinks can be cast to bring thermal management to cool modern electronics

Die cast heatsinks can be used as raw parts without any finish, or they can be anodized or powder coated for improved surface protection and corrosion resistance.

Any application where heat is generated and needs to be removed: Regardless of your application, you can trust Pioneer Thermal to develop a customized heat sink that can meet your requirements. We’ll work closely with you to design and manufacture the best solution for your needs and budget.

We can provide die cast heatsinks in a variety of applications, include but not limited to:
Circuit boards (PC boards):
High powered lasers
LED (light emitting diode) boards
Audio equipment
Communication equipment (such as cellular & satellite devices)

Die Cast Heat Sink Manufacture Process

Die casting is the manufacturing process of injecting liquid molten metal under high pressure into a high precision mold. It is often used to mass produce complex three-dimensional structures with a detailed surface texture:

• Create the Die mold
• Lubricate the Die
• Fill the die with molten metal
• Ejection from the cover die half
• Shakeout from the ejector die half
• Trimming and then grinding the excess material
• Powder coat, Paint, or Anodize the Diecast Heatsink

Die cast heat sink materials:

1.Al AA380 2.Al AA384 3.Al AA386 4.Al AA390 5.Magnesium AZ91D 6.Zinc Die cast heatsink is commonly used on automotive battery packcage now, PT heatsink has rich experience producing die cast heat sink & friction stir welding component to die cast heat sink for automove industry.
