On the blow molding floor, you don’t gamble with preform heating. When the heating tunnel isn’t pulling its weight, stretch goes sideways, flash shows up, or bottles come out weak—then you end up throttling the line just to cover the risk. On SIG machines, the infrared lamp has to deliver repeatable output at the voltage the machine is expecting. What matters, technically We run a 480V 3000W infrared lamp built for SIG blow molders, using a quartz halogen emitter and a standard R7s connector. The 480V rating matches common plant power, so you don’t need step-down transformers and you don’t add cabinet heat. The 3000W gives you the watt density to hit preform temperature fast, which keeps cycle times stable. The quartz envelope takes the thermal shock inside the heating tunnel, and the filament geometry is chosen to spread radiant heat evenly across the preform shoulder and body. Why it works in practice In stretch blow molding, the preform has to land inside a tight temperature window before it hits the mold. With this lamp, warm-up is quicker and zone control is tighter, so scrap drops and bottle weight stays consistent. That means fewer line stops chasing temperature drift, and more predictable bottle strength. Energy use comes down because the lamp heats on demand with minimal thermal lag, and the long service life cuts replacement frequency—fewer spares, less downtime. A few shop-floor details Installation is straightforward, but check the lamp length and R7s clearance against your specific SIG model. Tight reflector spaces can make fitment tight if you assume one size fits all. Also confirm your supply is truly 480V; voltage variance pushes the lamp outside its design point and shortens life. Handle the quartz tube by the base only, and keep reflectors clean—film build scatters infrared energy and robs heating efficiency.
