Abstract
Publisher Summary This chapter provides an overview of hydroforming fundamentals adapted to gain insight into the essential requirements for the development and execution of micro-hydroforming processes. Besides the description of the hydroforming principle and necessary additional manufacturing steps to obtain the required component shape, this concerns the determination of forming loads, the choice of suitable tube materials, and the definition of feasible component geometries as well as details on tool and machine design for mass production. Micro-hydroforming is a new manufacturing method for the mass production of tubular complex-shaped metal micro-components with integrated structures. It is based on the forming of initial tubes by internal pressurization with a liquid medium. Potential applications concern the production of corresponding components for medical devices, micro-fluidic and micromechatronic technology. Important advantages of micro-hydroforming consist in the possibility to generate complex geometries with reduced effort in machining and joining operations as well as in process time, compared to methods used until now for the manufacture of such components. As micro-hydroforming is characterized by comparatively high forming loads and pressures, the application of this forming technology implies an enhanced knowledge of an adequate process design to obtain economic and reliable production.
