As the simulation ran, the screen filled with vibrant heat maps. He watched the virtual "melt front" as it entered the cavity.
The clock in the R&D lab at Apex Precision struck 2:00 AM. Elias stared at the physical prototype of a new medical inhaler casing—it was a disaster. Every piece coming off the line had a visible "weld line" right across the main grip, making it structurally weak and aesthetically rejected.
By 7:30 AM, the first physical part with the new design popped out of the mold. It was flawless. When the stakeholders arrived, Elias didn't just show them a piece of plastic; he showed them the simulation data that proved the design was now built to last.
"There," Elias pointed. "The two fronts are meeting at too low a temperature because of the gate placement. They aren't 'welding'; they’re just touching."
