Sand Casting Technology

Nopatech™ gives you complete freedom in your casting  purchases. Moulds without patterns make rapid prototyping a breeze, short production runs competitive and replacing critical castings faster than you thought possible.Going directly from CAD to CAST skips the pattern fabrication and saves you thousands of dollars.With the help of Nopatech™, Saguenay Foundry can produce ductile & gray iron castings from 200 to 10,000 pounds in the fastest way possible without compromising quality.

Nopatech is a nine-axis machining tool specially designed to machine no-bake sand moulds directly. This technology allows us to produce custom-made iron castings without any pattern.By using high precision tools mounted on a nine-axis machining tool, we can produce moulds for almost any part, whether symmetrical or not, small or big, simple or complex, and offer a quality surface finish that will be very competitive with traditional pattern-made moulds.

The technology is also the best way to do urgent castings since it can have a cast part shipped much faster than all the alternatives, being quicker than weldments or foam patterns.We simply use the drawings that you will provide and virtually add machining stock and an appropriate gating system. One of our technicians will then convert this 3D drawing to machining instructions. A few hours later, a sand mould will be ready to be assembled and then poured by our employees.

Saguenay Foundry has always been proud to offer consistent castings at competitive prices. Although this new process is extremely fast, it doesn’t compromise quality because time is gained by suppressing pattern fabrication entirely, which could take up to 8 weeks.We use raw materials of great quality and we enforce strict supervision of all the processes required for a good finish product, from sand and iron quality to painting and machining.
