I keep seeing guys in our shop skip the full preheat on the core boxes for our gray iron castings. They say it saves 15 minutes, but I've seen three blowouts this quarter from cold spots. What's the actual time versus risk here?

Ever try to save 15 minutes and end up losing half a day? That math never works out.

Saving 15 minutes is a false economy. Those blowouts cost hours in cleanup, scrap metal, and machine downtime. A rushed job means you're redoing it later. The preheat cycle exists for a reason, and skipping it is just gambling with the whole pour.
