Patternless castings for short production runs of iron parts
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 patternless sand 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.
