Stop Overpaying for Krones Contiform Parts
If you’re running a Krones Contiform line, you already know the headache: the OEM parts are expensive. It feels like a tax just for keeping your machines running. We decided to fix that. We make blow molding heater lamps that slide right into your existing setup. No modifications, no fuss. You get the same heat profile your PET preforms need, but without the eye-watering price tag. The nitty-gritty on heat Here’s the thing about PET: if it cools down before it hits the mold, you’re in trouble. That’s why we build these for high-voltage, high-wattage output. On a 400V system, these lamps hit the heat density required to soften the plastic fast. We’ve matched the length and wattage to the original Krones specs exactly. Why? Because if the wattage is too low, your cycle times drag. If it’s too high, you’ll start scorching the plastic. It’s a delicate balance, and we’ve already done the math for you. Quartz and connectors (where things usually break) We use heavy-wall quartz glass and halogen gas fills. It sounds technical, but all it really means is that the filament can run hotter, which pushes out more infrared heat. Then there are the connectors—mostly R7s or Sk15. These aren’t your average plugs. They’re designed to handle the constant expanding and shrinking that happens during a long shift. A loose fit is a nightmare; it leads to arcing, and before you know it, you’ve burnt out the socket. These just stay put. A quick heads-up on installation You can wire these directly into your Krones oven. They fit the same footprint, so it’s a simple swap. But a word of advice: high-output lamps put a bit more stress on your cooling blowers. If your ventilation is clogged or just tired, the ambient heat will build up inside the oven. That’s a shortcut to killing your lamp’s electrodes. Do yourself a favor—check your airflow every time you swap a batch of lamps. It’s a two-minute job that keeps your gear lasting a lot longer.
