On the blow molding floor, heating drift will eat your uptime for lunch. When the preform temperature isn’t locked in, you’re staring down rejects, slower cycles, and a heating tunnel that’s always chasing the setpoint instead of sitting on it. We built the golden reflector infrared tube to stop that loop—dropped into the same specs you’re already running on the OEM machines. What matters, technically This is a short-wave infrared emitter, built for PET stretch blow molding. The golden reflector focuses the output and cuts stray heat, so you get better uniformity across the preform neck and body. The numbers line up 1:1 with the mainstream blow molders:
- Power: 1.0–1.5 kW per tube, 230 V (120 V also available)
- Dimensions: 1180 mm overall, 1050 mm heated length, 16 mm tube diameter
- Connector: R7s base, direct-fit alignment
- Response: full output in under 2 seconds, stable output within ±2% over the heating profile
- Life: 5,000+ hours typical, with output drift under 5% Why it works on your floor Pop it into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB heating tunnels, and it lands in your existing sockets and control logic without rewiring. You get faster thermal recovery after bottle changeovers, more consistent preform surface temperature, and fewer temperature-related flash and stress-crack issues. Energy use drops, too—the reflector cuts wasted heat, so the tunnel can run closer to the target heating curve. Here are the real-world details The lamp and reflector have to match. If your reflector geometry is off or the socket spacing is worn, you can still get uneven heating even with a tube that’s the correct length. Check the mounting brackets, the reflector condition, and airflow around the emitter—clean reflectors and steady airflow are what keep the heating profile stable.
