Patternless Moldmaking Works for Large Parts

摘要

A new moldmaking technology, Nopatech, makes it possible to produce prototype and short-run castings in one to two weeks using a nine-axis robot to machine blank sand molds. The process produces cores and molds from 20 × 20 in. (50.8 × 50.8 cm) to 115 × 115 in. (292.1 × 292.1 cm) without patterns.
