Stop Overpaying for Your Krones Contiform Lamps

Let’s be honest: OEM parts for a Krones Contiform line are expensive. It feels like every time you look at the maintenance budget, a huge chunk of it is just going toward lamps. We decided to fix that. We built a drop-in replacement lamp that does exactly what the original does, but without the “brand name” price tag. It’s designed specifically for the heat demands of PET preforms. Getting the heat right The whole game of blow molding comes down to wattage and voltage. If you don’t hit those numbers, you’re in trouble. Our lamps are built for the heavy-duty voltage of industrial ovens, packing a lot of power into a small space. This means your machines heat up fast. You get that intense heat needed to soften the PET, but it stays focused so you don’t accidentally melt the neck of the preform. One quick tip, though: if you’re running these at full blast, your cooling fans are working overtime. Keep your vents clean. If they’re clogged with dust, your lamps will burn out way faster than they should. Built to last (and fit) We use heavy-wall quartz glass here. Why? Because cheap glass bows and warps when things get hot. This stuff stays straight. Plus, the halogen cycle keeps the tungsten filament from evaporating too quickly, so the lamp actually lasts. As for the install? It’s a breeze. We use standard R7s connectors. You don’t need to rewire anything or buy fancy new sockets. Just pull the old one out, pop the new one in, and you’re back in business in a few minutes. Better bottles, lower costs We’ve all seen it—uneven heating leads to wonky wall thickness in the bottle. It’s a headache. Our lamps put out a consistent shortwave IR output. This makes sure the preform hits that “sweet spot” temperature evenly all the way around. You keep the same cycle times you’re used to, but your cost per bottle drops. It’s a simple way to shave some money off your operating costs without worrying if the quality is going to slip.

Stop Stressing Over IR Bulb Compatibility

If you’ve spent any time in PET blow molding, you know the headache. You need a replacement IR bulb, but finding one that actually fits the footprint and voltage of an old SMF machine—or even some of the newer global brands—feels like a scavenger hunt. We got tired of that. So, we built our replacement radiators to just work. We focused on the dimensions and electrical tolerances that most of these machines share, meaning you can stop worrying about whether the part will actually fit when it arrives. Getting the heat right Here’s the thing: you need that intense, short-wave radiation to soften the preform fast, but you can’t accidentally melt the neck. It’s a delicate balance. We use high-purity quartz glass because it doesn’t crack when things heat up and cool down rapidly. We also tuned the wattage and voltage (usually between 230V and 400V) to hit those OEM specs. The result? Your ramp-up time stays the same. Your cycle times don’t budge. No fancy rewiring needed Nobody wants to spend their weekend fabricating custom brackets or messing with the wiring. That’s why we stick to R7s and SK15 connectors. You just pop them in. Inside, we use halogen gas to keep the tungsten filament from burning out too quickly. It keeps the light output steady for thousands of hours, so you aren’t swapping bulbs every other week. A quick tip on reflectors But wait—there’s a catch. You can put the most expensive, high-wattage tube in the world into your oven, but if your reflectors are pitted or oxidized, you’re wasting your money. The heat won’t hit the preform correctly, and you’ll end up with cold spots in your bottle walls. Do yourself a favor: clean your reflectors every time you swap a bulb. It makes a world of difference in efficiency. We keep the most common lengths and power ratings for SMF-style ovens in stock. You can swap them out during a scheduled teardown and get the line moving again without waiting weeks for a branded part to ship from halfway across the world.

Cutting the Cost of Krones Contiform Heating Modules

Let’s be honest: OEM infrared lamps for Krones Contiform machines are expensive. Really expensive. When you’re staring at those invoices, it feels like you’re paying a massive premium just for a brand name on a box. We figured there was a better way. We’ve put together a technical alternative that gives you the same heat density and spectral output as the originals, but without that eye-watering markup.
