Making Your Krones Contiform Lamps Actually Work (Without the Headache)
When you’re looking for replacement infrared lamps for a Krones Contiform 1/2 or any of the big PET blow-molding setups, you don’t want a “project.” You just want the machine to run. That’s why we build our lamps to be true drop-in replacements. We don’t guess on the specs. We stick to the hard physics of shortwave radiation and standard electrical footprints so that when you plug them in, they just work. The deal with power and voltage Industrial grids are messy. Voltage swings happen. If a lamp isn’t built to handle those shifts, or if the ohms rating is slightly off, you’re in trouble. Even a tiny 5% difference in wattage can ruin a batch. You’ll start seeing cold spots in the plastic, which means your bottle walls end up uneven. Not a great look. We make sure the heat distribution is dead-on so your bottles come out consistent every single time. Quartz and connectors (The boring but important stuff) Thermal cycling is brutal on equipment. To stop your lamps from burning out early, we use high-purity quartz glass. We also stick to standard R7s or SK15 connectors. Why? Because nobody wants to spend their afternoon rewiring an oven or messing with lamp holders. It’s a simple swap. Plus, we add specific coatings to the quartz. This pushes the energy directly into the PET material instead of letting it waste away by heating up the oven walls. Real talk: Life on the shop floor These lamps put out a massive amount of heat. Here is a pro tip: check your ventilation and cooling fans. If they’re clogged with dust or blocked, the heat builds up around the ends of the lamp and kills the filaments way faster than they should go. Keep it clean, and your lamps will last. We keep these in stock and ready to ship. No waiting weeks for an OEM part to arrive while your line is down. Just swap them out, calibrate your heat zones, and get back to work.
