Can a heater swap actually get you more bottles?

If you’re running a mid-tier or older blow molding machine, you’ve probably hit that wall. You know the one. You want more bottles per hour, but your oven just can’t get the preforms up to temperature fast enough. It’s frustrating. The good news? You don’t necessarily need a brand-new machine. Sometimes, just swapping out your infrared heating elements is the fastest way to move the needle.

Let’s talk about heat density

If you want to shave seconds off your cycle time, you need more heat hitting the plastic, and you need it fast. We build these KRONES-compatible lamps to push concentrated short-wave radiation. By moving to a higher wattage, you’re basically flooding the PET wall with more energy. This means the preform hits its glass transition temperature much quicker and over a shorter distance. **One quick warning, though.**Check your power supply first. If you toss high-wattage tubes into a system with thin wiring or a tired transformer, you’re going to trip breakers or fry your contactors. Not a fun way to spend a Tuesday.
