Every second you shave off cycle time goes straight to your bottom line. Think about it. You're running a part with a 45-second cycle. Cut that to 40 seconds and you've increased throughput by 11%. That's 11% more parts per shift, 11% better machine utilization, 11% lower cost per part. Over a production run of a million parts, those five seconds add up fast.
I've seen it a hundred times. An engineer designs this brilliant part—sleek, functional, elegant. Then they send it to the molding shop and reality hits. "Yeah, we can't actually make that." Or worse: "We can make it, but it'll cost three times what you budgeted and take twice as long."
Here's a conversation that happens way too often: Engineer designs a part in California. Specs a plastic that works great in their 72-degree lab. Ships it to Michigan for production. Six months later, parts are failing in the field because nobody considered what happens when that plastic sees actual Michigan weather.
You pull a part from the mold and it looks perfect. Dimensions check out, surface finish is clean, everything's great. Then you come back an hour later and the damn thing's twisted like a potato chip.
Look, if you're running injection molding operations in Michigan, you've probably stared at a reject bin full of parts and thought, "What the hell happened here?"
