Stop Letting Your OEM Hold Your Blow Molding Line Hostage
If you’ve spent any time in blow molding, you know the frustration. You need a replacement lamp, but the specs are so proprietary that you’re stuck buying from one single OEM. It’s a bottleneck that costs time and money. We got tired of that. So, we built infrared replacement lamps that actually play well with others. They fit about 95% of the setups out there—including SIG machines—without the headache.
How we make them fit
It’s not just about the length of the quartz tube. That’s the easy part. The real trick is the electrical footprint and the physical connection. We stuck with the R7s and SK15 connectors because they’re the reliable workhorses of the industry. We matched the pin spacing and voltage tolerances of the original SIG gear exactly. The result? A drop-in replacement. You don’t have to rewire a thing or mess around with the lamp holders. You just put it in and get back to work.
The grit and the heat
We use high-purity quartz glass doped with halogen. Why? Because it lets the filament run hotter without just giving up and burning out. This gives you a concentrated short-wave IR emission that punches through PET preforms way faster. Depending on what your oven can handle, we’ve got various wattage and voltage options to match your power supply. **One quick warning though:**If you decide to go with a higher wattage than your original lamp, you’re packing more heat into the same amount of space. Make sure your cooling fans are clean and actually working, or you might find your sockets melting.
Real-world use
These lamps are built for the shop floor. They can take a beating in high-cycle environments. We also optimized the coating for thermal uniformity, so you don’t have to worry about weird hot spots ruining your bottles. When it’s time for a scheduled teardown, swapping these out takes minutes. Plus, since we keep these in stock, you aren’t stuck staring at an idle production line for weeks while you wait for an OEM shipment to arrive. Just check your voltage, check your length, plug it in, and run.
