Mould Design Tailor Made for Water Injection Technology

Abstract

Using the water injection technique, the part and mould design has a decisive influence on the hollow space formation and thus on the part quality. Only with a suitable design of the mould with regard to the gate and injector position and the part geometry can the WIT process be operated reproducibly, reliably, and thus economically. By using a modular test mould the influence of the design is systematically investigated and converted into useful design guidelines.
