Nopatech®

Nopatech^® is a rapid prototyping technology developed by Saguenay Foundry to produce iron castings without pattern.

Patternless iron castings for short production runs

In an increasingly competitive world, very short productions runs can become critical. For instance, prototypes needs a lead time as short as possible with a design as faithful as possible to the final parts that will be produced in larger quantities.

Patterns used to be the only alternative, but it was a long process with an average production cycle of at least eight weeks. By fabricating castings without pattern, the lead time can be dramatically reduced, with a cost that is also substantially lower in the vast majority of cases.

The advantages of rapid prototyping casting

Nopatech™ is a new process developed by Fonderie Saguenay ltd to achieve a simple goal: castings from CAD to CAST in the shortest possible lead time. Controlled by powerful software, a 9-axis robotic arm machines blank sand moulds to the final shape to obtain patternless castings in as little as a week.

The iron castings produced with this process are less expensive because of the low start-up cost, done faster, with a surface finish as good as the one of sand castings made with a traditional wood pattern.
