Customer Brief: Nypromold

At NyproMold CFdesign upfront CFD has a major impact on customer satisfaction.

“We have a far greater confidence that timelines will be met and first-off parts will be acceptable,” states CAD/CAM application engineer Paul Mailloux. “We are able to provide the best cooling scenarios and therefore improved cycle time, part quality and process windows that would otherwise be unachievable with mere guesswork.”

Integration between CFdesign and Pro/ENGINEER software used by NyproMold allows the company to conduct iterative design studies without any translation, conversion or data loss. Volumes, void-filling, boundary conditions and material properties are assigned automatically in CFdesign.  Associativity of all geometry is maintained as the assembly moves between CAD and CFD iterations.

Innovation without Guessing or Rework
In a recent project NyproMold began with an existing high-cavitation tool design employing traditional cooling circuits. Mailloux and associates conducted a design study involving several conformal cooling scenarios that could be produced using their laser sintering system.

“The ability to overlay and compare various iterations of cooling circuits within CFdesign to determine the best cooling concept was extremely valuable to us,” says Mailloux. “Then, there were the fast processing and quick results: Even during the computations, dynamic results were available for review and interaction. This enabled early decision-making prior to actually finalizing the computations.”

“We basically removed all guesswork and rework upfront, and were able to then take full advantage of laser sintering at the back end,” says Mailloux.

40% Faster Molding Cycle, Higher Quality Parts, Big Annual Savings
The improved cooling of the final high-cavitation tool reduced cycle time by more than 40 percent, from 23 to 16 seconds.

“In terms of injection molding, this is a radical improvement amounting in tremendous annual savings to our customer,” says Mailloux. “Only CFdesign could have led us down this decision-making course to reach such a successful result.”

“NyproMold brings many, many years of cooling expertise to the table and can often predict what is needed for good cooling circuits,” says Mailloux. “CFdesign can confirm and/or correct the original predictions. It has replaced guesswork with accurate, concise data that gives us the confidence we need to design and build molds right the first time. This is extremely important to us as there is never enough time or capital to do the same job twice.”
