Success Story

Circuiting Simulation Saves the Day

Circuiting Simulation Saves the Day

Customer challenge

When designing a new injection mold, the main goal of Superior Tool & Mold, based in Old Castle, ONT is to put their client in the best position possible to make quality parts consistently and efficiently.

Project goals

Getting the most out of a cooling design involves figuring out how to get around obstacles such as melt delivery systems (hot runners, cold runners, gates), part ejection, and mold action (slides, lifters). These obstacles can usually be overcome by using sound mold design principles, cooling simulation and some creativity. But cooling a mold uniformly isn’t just about getting the cooling lines in the right place. It also requires supplying the right amount of water, effective circuiting and using simulation to get it right—the first time.

Solution

There was a significant reduction in the amount of water required after circuiting, yet turbulent flow was maintained, along with acceptable ΔT’s. There are a couple of ways to implement the circuiting recommendations—internally or externally. Circuiting/flow diagrams should be provided for each mold. If possible, internal circuiting should be used because it reduces the amount of plumbing that needs to be done at the press. There will also be less possibility of misinterpreting the circuiting instructions.

Business outcome

Autodesk Moldflow software in-house allows Superior Tool & Mold to run various scenarios of cooling analysis and find the most efficient circuiting. Efficient cooling reduces cycle time by 6%. This is a savings of approximately $48,000 per year.

Conclusion

Making the investment in cooling simulation with Autodesk Moldflow Insight will help make better molds and will set up customers to mold quality parts more consistently and efficiently. That has helped Superior win more business. Remember, it’s not just the placement of cooling lines that matters, it’s also important to get the circuiting right.

Windage Success Story

Windsor, Ontario-based Build-A-Mold Ltd. conducted simulation work on an automotive oil pan mold for which it had severe warpage concerns that were based on the company’s experiences with previous molds molded from similar glass-filled nylon materials.

Gate Size and Location to Reduce Warpage

Caterpillar needed to determine the gate location and size with these factors in mind: 1) Flow balance and flow direction - This is particularly important for the glass fiber filled material used. 2) Gate location and fiber orientation - Needed the proper gate location for the least amount of warpage, which helps assemble the part more easily.
