Our SpinMeld™ friction spin welding systems can join steels, aluminum, cast or sintered metals, carbide materials, magnesium, nickel, molybdenum, and other exotic materials that normally may not be welded using other methods. The SpinMeld process is servo controlled with a high-speed spindle bringing critical parameters under control with in-process monitoring to improve part quality and eliminate post weld inspection.
SpinMeld can lower the cost to manufacture a wide range of applications where a high strength, non-porous joint is needed. Because the process is very fast, with weld times typically under 3 seconds, it is often possible to replace other processes including arc, resistance and projection welding with better results. The chief advantage of SpinMeld is the ability to produce a superior joint on a wide variety of materials without altering the crystalline structure of the base materials and so the joint strength is very high and the heat affect zone small.
SpinMeld systems are available with automatic parts handling and inspection, as stand-alone units or may be integrated into a turnkey solution. Each machine is designed to fit the individual application with parameters such as rotational speed, cycle time, and forging force fully customizable.
SpinMeld is appropriate for high volume environments where at least one of the components is cylindrical in nature. At Coldwater, our efforts are focused on smaller part sizes, as indicated below:
Please contact us to discuss your specific requirements.
We accept applications for prototype project requests. Please submit your initial request for parts joining prototype work. We can work to produce custom parts that make use of advanced joining technology as well as apply a joining to your existing parts. Provide some of the information below and we’ll contact you for more details and state the process with your team.
