Getting Your Krones Contiform S Back Up and Running (Without the OEM Headache)
We build our infrared heating lamps to be simple, drop-in replacements for the Krones Contiform S and other big blow-molding setups. Now, some people think “universal” means a cheap, one-size-fits-all part. That’s not how we do it. To get a 95% compatibility rate, we focus on the gritty details—the exact electrical footprint and the thermal punch your PET preforms actually need to shape up correctly.
The Heat and the Power
Here’s the thing: the Contiform S is picky. If the heat density is off, you either end up with a preform that didn’t reach the glass transition temperature, or you accidentally melt the neck. To stop that from happening, we spec our tubes to match the OEM’s voltage and wattage exactly. We use high-wattage shortwave IR lamps because they heat up fast. Really fast. That’s the only way to keep high-speed lines moving without a hitch. The radiation hits the PET wall hard and fast, which is exactly what you want.
Built to Last, Not Just to Fit
Heat kills cheap glass. That’s why we use heavy-wall quartz. It keeps the tubes from bowing or warping when things get scorching hot inside the oven. For the connections, we stick with R7s or SK15 standards. Why? Because they just work. They create a tight electrical contact that won’t rattle loose, even when the machine is humming along at full tilt. Plus, if you want to be precise, we have coated options. These help aim the heat right at the preform body and keep it away from your machine frame.
Real-World Tips for Installation
Swapping these out is easy. You pull the dead tube, slide the new one in, and wire it up. Done. But a quick word of advice: if you decide to push higher wattages to squeeze more speed out of your cycles, you’re putting more stress on your power supplies. And please, check your cooling blowers. If they’re clogged with dust or acting up, you’re asking for trouble. Restricted airflow means overheated preforms or a lamp that burns out way too soon. The best part? We keep these in stock. You don’t have to deal with those agonizingly long lead times you usually get from the OEM. You get your parts, you fix the line, and you get back to work.
