Custom CNC Machined Aluminum Pin-Fin Heat Sink

Custom CNC machined components and sub-assemblies, ready to integrate into your equipment. We machine and assemble multi-part components — connector housings, bearing blocks, manifolds, mounting brackets and complete sub-assemblies — to your drawings or samples.

From drawing review and prototyping through batch production and full inspection, we handle the complete process in-house, including assembly and welding where required. Tight tolerances, consistent quality, and flexible order quantities from one piece to volume.

Trusted by Jabil and BYD for precision components. Share your drawing or RFQ and we will provide a quote with DFM feedback.

2. CNC Machining Capabilities  

We machine and assemble multi-part components and sub-assemblies, combining CNC turning, CNC milling, drilling, tapping, grinding and 5-axis machining in one in-house process.

CNC Turning — For cylindrical and rotational elements within an assembly — precision shafts, pins, bushings, sleeves, threaded connectors and stainless steel mechanical parts that require precise diameters, concentricity and smooth finishes.

CNC Milling — For housings, brackets, manifolds and structural bodies with slots, pockets, holes and mounting surfaces. Combining turning and milling lets us produce complete components with multiple machining requirements while keeping dimensions consistent.

Assembly and Integration — Beyond machining, we assemble multi-part components and sub-assemblies — connector housings, bearing blocks, manifolds and mounting brackets — with welding where required, so you receive components ready to integrate into your equipment.
