Rapid Manufacturing Method for Droppers Based on Rapid Prototyping and Manufacturing Technique

Aiming at the complex embedded labyrinth design of the dropper, which is the key part in a water saving irrigator, rapid prototyping and manufacturing technique is used to design the droppers and to manufacture the rapid tooling(RT). CAD design of the dropper using parametrization idea is described in detail. The CAD process model and the RT process model generation of the dropper are carried out taking manufacturing of the precision mould as the core. Prototypes are built up using RP technique to complete rapid verification and the modification of the dropper design. Finally, the integration of design/verification/manufacture of mould and products is realized, and the metal sprayed mould is made.
