On the blow molding line, uneven preform heating doesn’t just bog the machine down—it makes off-spec bottles and scrap that eat into your margins. When the heating tunnel can’t hold setpoint with repeatable intensity, you end up chasing temperature swings instead of running steady cycles. What matters under the hood We spec this halogen heater lamp for 230V systems at 1000W, giving you predictable infrared output for preform heating. The quartz envelope takes rapid thermal cycling in stride, and the compact profile drops straight into the standard reflector assemblies used across blow molders. It’s engineered to match OEM electrical and mechanical interfaces, including the common R7s connector, so you can swap out a worn emitter without rewiring the heating bank or hacking the mounting. Why this matters in stretch blow molding In stretch blow molding, the preform needs fast, uniform surface heating to transfer evenly into the mold. This lamp brings the heating tunnel back to its designed intensity profile, so you regain stable setpoint control and repeatable heating across the preform wall. You see fewer pinholes, better weight control, and less trim scrap. Energy stays in line because the lamp comes up to temperature quickly and holds output without overshoot. The practical details Install it with the tungsten filament in the right orientation—otherwise you’ll get hot spots and uneven wear. Keep the reflector clean and aligned. Misalignment changes the heating pattern more than most operators expect. Service life is about 5,000 hours in typical duty cycles. If you run it at full continuous output, life shortens, so plan replacements around preventive maintenance windows. Always verify voltage and terminal condition before energizing, and match the lamp to the exact wattage and base your blow molder specs.
