Fixing Those Pesky Cold Spots in Your KHS Blow Molder

Ever look at your PET bottles and see those annoying streaks or “pearls”? Or maybe the walls are thin in some spots and thick in others. It’s frustrating. Usually, it comes down to one thing: your heating oven isn’t hitting the preforms evenly. Most of the time, you’re fighting old lamps that have just worn out or bulbs that aren’t putting out the right kind of heat. We make high-output IR lamps that slide right into your KHS system to plug those thermal gaps and get your bottles looking clean again. The trick to getting the heat right It all comes down to how the filament is wound inside the quartz tube. Cheap lamps often have a “center-heavy” problem—they blast heat in the middle but leave the ends cold. We keep our tolerances tight so the heat is spread evenly across the whole length. When the infrared emission is stable, your preforms get a consistent soak. No surprises. But here is the thing: you’ve got to get the voltage and wattage exactly right for your power supply. If the voltage is too low, the filament will burn out way faster than it should. On the flip side, if the wattage is too low, your preforms won’t get hot enough to stretch. You’ll just be fighting the machine all day. The nuts and bolts of the hardware We use high-purity quartz glass because these things take a beating with constant heating and cooling. Most of our lamps use R7s or Sk15 connectors. Now, a tight fit here is a big deal. If there’s even a tiny gap in the socket, you get electrical resistance. That creates heat in the wrong place, and before you know it, you’re looking at a melted socket. Not a fun way to spend a Tuesday. A quick heads-up on speed It’s tempting to just crank up the heat density to shave a few seconds off your cycle times. But that comes with a trade-off. More wattage means more energy in the oven, which puts a lot more pressure on your cooling blowers. If your ventilation can’t keep up, you might actually overheat the electronics inside the machine. Before you switch to higher-density tubes, just double-check your airflow. It’ll save you a massive headache down the road.

Stop Fighting Your SIPA Rotary Machine

If you’re running a SIPA rotary, you know the headache of inconsistent heating. You see those annoying “cold spots” in your preforms, and suddenly your PET bottles have uneven walls. It’s frustrating. Usually, the problem is simpler than it looks: your power is mismatched. Here’s the thing. If you throw generic quartz tubes into a machine designed for a specific OEM wattage, things go sideways. Even a tiny 5% difference in power shifts the heat density. That’s why your operators are constantly fiddling with the oven temperature, trying to find a sweet spot that doesn’t exist. We build our infrared tubes to hit that power spec exactly. No guessing. When the voltage and wattage are locked in, the heat hits the PET resin at a steady, predictable rate. It just works. The nuts and bolts We use high-purity quartz glass because these things take a beating. Rapid heating and cooling (thermal shock) will kill a cheap bulb in no time. These are built specifically for the brutal environment of a blowing machine. We also obsess over the connectors. A loose fit isn’t just a flicker—it’s a fire hazard. A bad connection creates a hot spot that can melt your housing or fry the lamp way before its time. We make sure the fit is tight. Real talk for the shop floor These are drop-in replacements. You pull the old one out, wire the new one in, and you’re back in business. But a quick heads-up: if you’re buying in bulk to overhaul an older line, take a look at your wiring. High-wattage tubes pull a lot of current. If your cables are old and worn, pushing that much power through them creates resistance and heat. It’s worth a five-minute check to avoid a big headache later. When your tubes are consistent, your bottles are consistent. You stop fighting the equipment and actually start hitting your cycle times.
