In addition to its library of proprietary technologies, Remmele also licenses and develops key technologies alongside other leaders in the manufacturing industry. Some of these technologies are available for use on client projects, which can help Remmele's customers see stronger, more dynamic products which meet their budgetary goals.
Friction Stir Welding (FSW):
FSW is a licensed technology that enables manufacturers to create solid-state joints and seams that retain much of the original material's physical properties. FSW is useful for applications where warping through traditional welding can be an issue, where heat transfer properties are critical, or where a hermeic seals are needed.
FSW is accomplished by rotating a cylindrical tool along a seam to be joined. The tool is shouldered with a profiled pin that projects into the parts being joined. Heat is generated via rotational friction between the tool and parts. The heat causes the materials to soften without reaching melting point, and allows the pin to traverse along the joint. As the tool moves, the material in front of the pin is plasticized by the frictional heat and displaced to the back of the pin. At that point, material cools to form a solid state, full penetration weld.
The FSW process is effective on part thickness ranging from 0.050" (1.2mm) to 4.0" (100mm) when welded from both sides. Both butt and lap joints are acceptable weld geometries. Commercial use is currently restricted to welding aluminum alloys, however, there is increasing activity in developing the process for magnesium, copper, steels (ferritic and stainless) titanium and nickel alloys.
High Velocity Machining (HVM):
HVM is a metal cutting technique that utilizes very high spindle speeds with fast feed rates to maximize removal rates with minimal thermal impact. HVM capabilities at Remmele often allows customers to consolidate multi-component assemblies into monolithic HVM parts and skip labor-intensive assembly time and labor.
