Friction Stir Welding

Friction Stir Welding offers superior bonding and mechanical characteristics compared to traditional welding techniques. It creates virtually defect-free bonding, and the materials being joined never melt, resulting in better retention of their original mechanical properties. Our expert team can revolutionize your welding process with the power of Friction Stir Welding, providing you with the cleanest, strongest, and most efficient welds. We can join previously unweldable materials, minimize heat distortion, and avoid costly post-weld treatments.

Cold Plate Manufacturing

Our cold plate manufacturing services use cutting-edge technology and expertise to provide high-quality custom cold plates for various high-tech industries. Cold plates transfer heat from a device to a liquid, which flows to a remote heat exchanger and dissipates into either the ambient or to another liquid in a secondary cooling system, providing localized cooling. Whether it’s prototyping or mass production, our expert team has the capacity to fulfill all your cold plate needs, ensuring exceptional quality every time.

Wire EDM

Wire EDM is a precise and cost-effective toolmaking solution widely used in mold and die manufacturing, including for extrusion dies and blanking punches. It’s ideal for both prototypes and full production runs and is prevalent in industries such as aerospace, medical equipment, automotive, electronics, extruder, punch, and die tooling. Our state-of-the-art wire EDM services provide exceptional accuracy and precision for complex part manufacturing, whether for prototyping or mass production. We have the expertise and capacity to fulfill all your wire EDM needs, ensuring high-quality parts while removing internal stresses and distortion caused by hardening.

Milling Services

Our expert team utilizes state-of-the-art equipment and software to create high-quality parts with unparalleled accuracy. With over 65 CNC mills and lathes, we provide Ultra Precision for low volume, repeat machining to the micron level of accuracy, with tolerances within 0.00005”. Our precision machining is supported by world-class quality departments, employing the use of CMMs and 3D scanning to ensure the quality and conformance of the part.

TAP Testing

We perform TAP testing to better understand the dynamic stiffness of the relationship between the tool and the workpiece in the machining processes. This allows us to develop stability maps that help us predict cutting performance and optimize our machining process, ultimately resulting in better quality finishes, more accurate surface locations, and improved cutting performance. TAP testing also helps us validate the consistency of our machine tools at the tip of the tool, which allows us to get to optimal cutting parameters quickly and efficiently, saving time and reducing costs associated with trial-and-error methods. By characterizing the dynamic stiffness of the tool and workpiece relationship, we can achieve better-cutting performance in a more predictable and reliable manner.

Kitting Services and Assembly

Our team of highly trained mechanical and electro-mechanical assemblers can integrate and assemble a wide variety of operations, ranging from complex telecommunications equipment to sophisticated thermal management devices. Our facilities are AS9100 and ISO certified to provide services including assembling both in-house manufactured parts and parts manufactured by a sub-supplier and sent to us for assembly or kitting.
