FSW Liquid Cold Plate Parts

KINGKA’s FSW (Friction Stir Welding) Liquid Cold Plate Parts are engineered for advanced thermal performance in high-power electronic applications. Manufactured using precision aluminum and copper materials, these cold plates are designed to efficiently dissipate heat in electric vehicles, data centers, renewable energy systems, and more. With the FSW technique, we ensure superior joint strength, leak-proof performance, and minimal thermal resistance.

FAQs

Q1: What is the benefit of using FSW instead of traditional welding for cold plates?
A1: FSW avoids melting the metal, resulting in stronger joints, no porosity, and better thermal performance.

Q2: Can you customize the channel layout for my specific application?
A2: Yes, we offer full design customization based on your thermal simulation or performance goals.

Q3: What is the maximum size of a cold plate you can manufacture?
A3: We can produce cold plates up to 800mm in length, depending on material and design.

Q4: Do you support small-volume prototyping?
A4: Absolutely. We offer both prototyping and high-volume production services.
