We’re not just making aluminum extrusions—we’re making the tough ones. Got ultra-thin fins, tricky shapes, or super tight tolerances? No problem. At Kaixin, we know heat sinks inside and out, and we’ve got the tools and experience to handle complex designs with ease. If it’s a challenge, we’re in.|

Kaixin also can provide a wide range of surface treatments, including anodizing, powder coating, sandblasting, etc. We obtain 4 automatic anodizing lines to anodize industrial aluminum profiles with a thickness of 30 μm and generally 10-15μm for our customers, featuring an anodizing-resistant coating while maintaining an excellent aesthetic appearance.

As an extruded aluminum supplier, we provide comprehensive in-house machining and welding services, streamlining your production process from extrusion to finished product. With one-stop manufacturing solution, we can shorten your lead time, improve quality control, and lower costs.
