Getting the Heat Right in High-Speed PET Blowing

Ever deal with “skinning”? It’s a nightmare. Your PET preform looks right on the outside, but the core is still cold. You end up with inconsistent bottles and a lot of wasted material because the heat just isn’t hitting the center. We’ve spent a lot of time fixing this for Krones Contiform S and Husky HyPET systems. We basically tweaked the infrared spectrum so the heat actually sinks in deep instead of just scorching the surface. The Power Problem When you’re running high-speed lines, you don’t have time to wait around. You need a massive amount of heat, and you need it in a tiny space. To make that happen, we use high-voltage setups. It lets us push way more wattage through the tube without making the lamp physically bigger. The result? The lamps hit their operating temperature fast. Really fast. When those preforms are flying through the oven, you need that aggressive heat ramp-up or you’re just guessing at your settings. The Secret is in the Glass We don’t just use standard clear quartz. That stuff lets too much energy bounce off. Instead, we use a specialized quartz glass with a proprietary coating. Think of it like a filter. It focuses the energy into the specific bands that PET actually likes to absorb. Instead of the heat bouncing away, it gets pushed straight into the center of the preform wall. And don’t worry about the installation. Whether you need R7s or Sk15 connectors, these are simple drop-in replacements. You just pop them in. No rewiring the oven or messing with your sockets. A Quick Heads-Up Here’s the thing: more penetration power means more heat inside your oven. If your ventilation is clogged or your cooling system is struggling, the ambient temperature is going to climb. If it gets too hot in there, your lamps will burn out way faster than they should. Just keep your airflow clear. It’s the easiest way to make sure your quartz lasts as long as possible.

On a blow molding line, heating isn’t just another function—it’s the first bottleneck in the cycle. When the heating tunnel runs uneven, preforms stretch differently from cavity to cavity. You end up with thin walls, heavier crystallization, and off-spec bottles that burn material and eat into uptime. The Krones Contiform 3 heater lamp is built to keep the infrared profile stable, so the blow molder can run repeatable cycles without chasing temperature drift. What matters, technically The Contiform 3 heater lamp is a short-wave infrared halogen emitter, engineered to match the original heating-zone geometry of the machine. It runs on the standard line voltage used in Contiform 3 heating modules, and the quartz tube is chosen for fast response and high radiant output density. The lamp uses an R7s connector interface, so it drops straight into the existing lamp holder—no rewiring the heating tunnel. In practice, you get preform heating back quickly after a lamp change, with less re-tuning of zone power and fewer rejects at startup. Why it works on the line Stretch blow molding demands a tight surface temperature window on the preform. If the lamp underperforms, you either jack up power or slow the line to compensate—both waste energy and add downtime. This Contiform 3 lamp is specified to OEM tolerances for length, wattage, and beam profile, so each zone delivers consistent heat flux across the preform surface. Plants that standardize on it see fewer heating-related line stops and a more predictable scrap rate, because the tunnel spends more time in steady state and less time in adjustment. The practical details Installation is straightforward, but remember: the heating tunnel is a hot environment. Always confirm lamp seating and reflector alignment, then back it up with a pyrometer scan of the zone. Misalignment shows up fast—one side hot, the other cold. Keep spare lamps sealed until you need them. Quartz performance can degrade with surface contamination. Expect typical lamp life in the 5,000–8,000 hour range, depending on line speed and power cycling. Schedule replacements around preventive maintenance windows so you don’t get caught by an unplanned stoppage.
