Abstract：In order to shorten the manufacturing time for new products, the use and development of modern production techniques are critical. The rapid prototyping (RP) system has been successfully employed in several ways to fabricate models, make prototypes, and even tool for the purpose of rapid manufacturing. The main advantage of electroforming is extreme dimensional accuracy in the creation of surfaces. In this paper, wax-RP has been adapted to transfer Cu-based electroforming that had been filled by backfilling for rapid tooling (RT). Dimensional accuracy, surface roughness, hardness and life of Cu-based RT were measured. Results show that tire-molds can be made by using RP patterns and Cu-based electroforming. Reducing the manufacturing cycle by 2-3 weeks.

With the rapid rise and expansion of the automobile decks on a large-scale, at low cost, and with a short manufacturing cycle are the key factors contributing to a competitive automobile industry. The defects of traditional mold manufacturing involve a complex, long and costly manufacturing involve a complex, long and costly manufacturing process. These factors create a potential bottleneck to successful and efficient mold manufacturing. It is widely recognized that the manufacture of the tire-mold based on the rapid prototyping (RP) and Cu-based electroforming technology has served as an important breakthrough in manufacturing technology.
