A Better Way to Handle Your SIG Blomax 4 Infrared Lamps

Let’s be honest: keeping a PET blowing machine like the SIG Blomax 4 or a Krones Contiform running smoothly is a constant balancing act. You want the heat to be perfect, but you don’t want your operational costs to spiral. When the OEM lamp prices start climbing, it feels like you’re being squeezed. You need a replacement that actually works, hits the same spectral output, and doesn’t mess up your heating profile. The nitty-gritty on power These lamps live and breathe short-wave infrared radiation. We build them to handle the heavy lifting—the high voltage and wattage needed to punch through PET resin fast. The goal is to hit that glass transition temperature ($T_g$) in a matter of seconds. If the wattage dips even a little bit below what the OEM spec calls for, you’re going to have a bad time. You’ll start seeing “cold spots” and uneven heating, which means your bottles end up with wonky wall thickness. Nobody wants that. Quartz and connectors We use high-purity quartz glass because these things go through a brutal cycle of heating and cooling. Cheap glass just burns out. As for the fit, we use R7s or Sk15 connectors. It’s not just about making them easy to plug in; it’s about getting a tight electrical connection so you don’t deal with arcing at the terminals. We also coat the quartz to shift the infrared spectrum. This pushes the energy into the plastic where it belongs, rather than wasting it by heating up your oven walls. Getting them on the floor The best part? They’re true drop-in replacements. You won’t need to mess with your wiring panels or modify your lamp holders. Just pull out the burnt-out tube, pop the new one in, and tweak your heating zones. It’s that simple. One quick tip: if you’re pushing these lamps to their max wattage, your oven’s cooling blowers are going to work harder. If your fans are clogged with dust or starting to fail, all that extra heat has nowhere to go, and it’ll kill your lamps early. Do yourself a favor and check your airflow before you install a high-output set. It’ll save you a headache later.
