Introduction
We build quartz halogen infrared (IR) heat lamps specifically for the demands of blowing machines. These lamps are not generic heaters; they are engineered to deliver intense, focused heat right where it counts—on the preform or parison. If your line runs PET or glass blowing, you need a heat source that turns on fast, holds temperature steady, and fits the machine footprint. This is what our lamps are designed to do.
Technical Deep-Dive: Power, Voltage, and Dimensions
The core specs—wattage, voltage, and length—exist to match the thermal load and physical space of the blowing process. A typical unit runs at 2500W and 400V. This high-voltage, high-power arrangement keeps current draw manageable while delivering the heat density needed to soften material quickly. The 300mm length is a practical compromise: long enough to cover the critical heating zone, compact enough to fit in tight machine cavities. We size the lamp to give you a repeatable heat profile. If you spec a lamp that is too short, you get uneven heating and weak spots. Too long, and you waste space and risk overheating nearby components. The 2500W rating at 400V means you need a supply and control gear that can handle the load. Plan your wiring, contactors, and thermal management accordingly.
Material and Design: Quartz, Halogen, and the R7s Connection
The tube is quartz for a reason. Quartz withstands rapid thermal cycling and runs hot enough to keep the halogen cycle working. The halogen cycle keeps the filament stable by redepositing evaporated tungsten back onto the filament. This stabilizes output over time and extends filament life compared to standard incandescent designs. The result is consistent IR radiation and predictable heating. We coat the quartz to shape the output. The coating filters visible light and reflects IR back toward the target. This increases the useful heat flux on the preform and reduces wasted energy. For installation, we fit the lamp with an R7s connector. R7s is a double-ended, linear contact base that locks in quickly and handles the current without extra hardware. It is a drop-in fit for many blowing machine reflectors and sockets, so you can swap a lamp in minutes instead of hours.
Application and Benefits in Blowing Machines
In blowing machines, timing is everything. The lamp must hit temperature fast and hold it steady while the parison rotates and stretches. Our quartz halogen IR lamps reach operating temperature within seconds, which keeps cycle times tight. The focused IR heat reduces the time needed to achieve the right material viscosity, which improves throughput and reduces scrap. The lamp’s footprint and output pattern are matched to the blowing geometry. The 300mm length and 2500W rating give you a concentrated heating zone that lines up with the preform wall. The R7s base makes it easy to wire up and replace on the line. The halogen cycle keeps output stable over thousands of hours, but it also demands proper cooling. These lamps run hot, so the machine must have adequate airflow and thermal shielding. If you do not manage the surrounding temperature, you risk shortening component life. For engineers running blowing machines, this configuration delivers fast response, stable output, and easy maintenance. We build it to take the heat, keep the process consistent, and fit the machine without redesign.
Reality Check on Performance and Limits
High heat density comes with trade-offs. A 2500W, 400V lamp delivers the intensity you need, but it also places real demands on the electrical system and the machine’s cooling. Make sure your control circuitry is rated for the inrush current, and ensure the lamp’s mounting and reflector can handle the thermal load without deformation. Treat the lamp as part of a system—wire it up correctly, keep the airflow steady, and it will perform. Neglect the surroundings, and you will burn out components faster than expected. We design these lamps to be the workhorse in your heating station. They are built for the rhythm of blowing: rapid heat, stable hold, and quick swap-outs when service is due.
Summary
Quartz halogen IR heat lamps for blowing machines deliver fast, focused, and stable heating. The 2500W, 400V rating and 300mm length are matched to the process window, while the quartz tube, halogen cycle, and coated surface maximize useful IR output. The R7s connector makes installation straightforward. Expect high performance, but plan for the thermal and electrical demands. That is how you keep the line running.
