The Lamp That Gets Your KHS Blow Molding Back on Track
Ever had one of those days where your KHS blow molding line just can’t get its act together? You’re staring at uneven heating, and it’s messing with everything. Chances are, the heat source itself is the culprit. We built a replacement lamp to fix exactly that. It’s a direct fit, designed to bring back the precise thermal profile your machine needs to heat PET preforms evenly, every single time.
The Power Behind the Performance
Here’s the thing about getting the heat right. This lamp runs at 2500W and 400V. That power level is what gives you the high heat density you need, packed into a compact space. It’s how you get preforms up to the perfect stretch temperature quickly, without needing a heater block that’s way too big. And the 300mm length? It’s a perfect match for the standard heating zone on your KHS machine. That 400V rating is smart, too. It pulls less current than lower-voltage options, which means less strain on your machine’s wiring and less voltage drop over long runs. But—and this is important—that power creates a lot of ambient heat. So you need to make sure your machine’s power supply and cooling circuits are up to the task. They’ve got to be able to keep up.
Built to Last, Built to Fit
The tube itself is made from coated quartz. Why? Because it can handle the constant heating up and cooling down without breaking down. The coating also keeps the heat distribution steady across the whole tube, so you get a reliable, even heat field from one end to the other. Then there’s the R7s connector. It’s the industry standard, and for good reason. It locks the lamp in place with a solid, mechanical fit. That means it’s a true drop-in replacement, so you can get it installed fast and get the machine back online. And let’s be honest, that matters when you’re trying to avoid downtime. The R7s design also keeps the electrical contacts stable, even when the machine is vibrating—which, let’s face it, it always is.
What This Means on the Shop Floor
Uneven heating is a nightmare. It shows up as inconsistent wall thickness and bottles that just give up. A stable heat field across that 300mm zone gets rid of hot spots and cold seams, so every preform stretches the same way. This lamp is made to be a direct fit for your KHS blow molding machine and compatible Aoki setups. Installation is a breeze. Pop out the old lamp, line up the new one with the R7s ends, and you’re done. No messing with the holder. No rewiring. Just remember, with that 2500W power, you need to make sure your machine’s cooling and power circuits are in good shape. If they are, this lamp will restore the heating performance your line was built for, and keep things running at the speed you need.
