Dealing with Heat Issues in PET Blowing

If you’re running KHS or Nissei ASB 150DP machines, you know the frustration of uneven heat. One minute everything is fine, and the next, you’ve got wall thickness variations or bottles that just look… wrong. It usually comes down to “hot spots” in the thermal field that chew up your preforms. We decided to fix this by getting obsessed with the details. We tightened the tolerances on where the filament sits and how thick the quartz envelope is. It sounds small, but it makes a massive difference in how the heat actually hits the plastic. The nitty-gritty on power The Nissei ASB 150DP is picky. It needs a very specific wattage-to-voltage ratio to get the infrared flux just right. To handle that, we use high-purity quartz. Why? Because standard glass warps when you cycle the heat up and down all day. By using a higher voltage rating, we can keep the lamp compact without losing any heat density. You get a concentrated beam that hits exactly where the mold needs it. No wasted energy, no guessing. Getting them installed Nobody wants to spend their weekend rewiring a machine. That’s why we stuck with standard R7s and SK15 connectors. They’re drop-in replacements. You pull the old one out, pop these in, and you’re back in business. Inside the tube, the halogen cycle stops the tungsten filament from evaporating too fast. This means your light output stays steady for thousands of hours. We also added a special coating to the quartz that bounces the heat inward. It keeps the machine’s chassis cooler and saves you a bit on the power bill. A few warnings from the shop floor Here’s the thing: these lamps put out some seriously intense shortwave IR radiation. They solve the uniformity problem, but they can’t fight dirt. If your reflectors are covered in dust or carbon buildup, the precision of the lamp doesn’t matter—the heat won’t hit the target. Keep those mirrors clean. And one last tip. If you’re swapping in high-output tubes, keep an eye on your power supplies. If your capacitors are getting old, that initial startup surge can trip your breakers. Just double-check your electrical specs before you flip the switch.
