The technique of precision rapid mould by transferred coating forming is an innovative rapid tooling (RT) process. It combines many techniques such as transferred coating and rapid prototyping. The main advantages of this process compared with other RT processes are low investment and production cost, shorter production cycles and many kinds of scale tool. The manufacturing process and the coating materials have been researched. The results of application show that net shape production may be fabricated in 2–7 days. The surface roughness of tools, Ra, can reach 1.6–6.3 äm, and dimensional accuracy may attain CT4-CT6.
