Preforms have to land in that tight temperature window, every cycle, without fail. If the heater goes down, the line stops—scrap climbs, oven temps wander, and you burn minutes you can’t get back.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We build Teflon-insulated infrared heaters that have to live in the tunnel and still deliver repeatable heat. The conductor is nickel-chromium alloy, running in a quartz or ceramic body, with PTFE insulation rated for continuous exposure up to 260°C. In practice, that lets you run the high temperatures PET stretch blow molding demands without the insulation turning brittle. Each element is specified to match the OEM’s watt density, voltage, and geometry—typically 400–2,000 W, 100–240 V, and lengths that fit standard heating zones. Connections are done to standard terminals and R7s bases, so the element seats clean and transfers heat with minimal contact resistance.</p>
