Latest Patents

VandePolder's latest patents include the "Extended jacket end, double expansion hydroforming." This invention involves hydroforming double wall tubular stock into an air gap tubular element. The process begins with providing a plural wall tubular workpiece that has an inner wall liner and an outer wall jacket. One of the jacket ends is extended axially beyond the adjacent liner end and flared outwardly. The workpiece is then placed into a mold cavity, where hydroforming fluid is injected to expand the liner and jacket. After releasing the pressure, the workpiece is moved to a second mold cavity for the jacket, where hydroforming end closures are applied to seal the jacket ends. This innovative method allows for the creation of complex tubular structures with enhanced performance characteristics.
