Getting Your SIG Blomax 4 Back Up to Speed

You don’t always need to buy a brand-new machine just because your old SIG Blomax 4 is acting up. I see it all the time. Operators get frustrated because their wall thickness is all over the place or the cycle times are dragging. Most of the time, the culprit is simple: the original infrared lamps are just worn out. They’ve lost their punch. The quickest way to get your productivity back? Swap those old bulbs for some precision-spec’d shortwave IR lamps. The heat side of things Here’s how it works. To get a PET preform ready for blowing without melting the neck, you need a very specific kind of heat transfer. We build our replacement lamps to fit the original footprint, but we tighten up the wattage tolerances. When you increase the wattage per millimeter, you get a stronger heat flux. In plain English: you can run the machine faster. But a word of caution. Don’t just crank the power to the max. If you go overboard, you’ll scorch the plastic or fry your power supplies. Balance is everything. The nitty-gritty on hardware We use high-purity quartz glass because it lets the IR light through without blocking it. For the connections, we stick with R7s or SK15. Why? Because they fit tight. A loose connection is a nightmare—it creates a hot spot that can literally melt your socket. We also use halogen gas fills. If you’re running 24/7 shifts, you don’t want to be climbing into the oven every few weeks to replace a burnt-out filament. These last much longer. Making it work in the shop The best part is that these are drop-in replacements. You don’t have to mess with the wiring or spend a weekend re-engineering the oven. By using lamps with a consistent output, you kill off those annoying “cold spots” in the heating zone. That means fewer rejects and a much smoother blow process. One last tip: more heat density means the inside of your oven is going to get hotter. Before you start, check your cooling fans. Make sure they’re clean and actually spinning. Otherwise, you’re just baking your own electronics.
