R7S 10mm 2250W Halogen Lamp: The Heat Behind the Blow
We built the R7S 10mm halogen lamp for one reason: to handle the intense heat that blow molding and glass blowing machines throw at it. It’s all about getting that focused, radiant heat exactly where you need it—right on the parison or the mold.
Power and Size: Why It Matters
That 2250W rating isn’t just a number. It’s the power needed to hit high heat density, so you can melt PET resin fast and keep it at the right temperature through the whole blow cycle. And the 10mm tube diameter? That’s intentional. It slips into tight spots without forcing you to rework the machine. This kind of power means the lamp comes up to temperature quickly, which cuts down on that painfully long machine warm-up time on the floor. But here’s the catch: 2250W is a heavy draw. Make sure your wiring and contactors are rated for continuous high current. Otherwise, you’re asking for trouble.
Built to Last in a Tough Job
Inside, you’ve got a halogen cycle quartz envelope. The payoff is simple: it keeps the filament from darkening, so the lamp holds steady on both light and heat for a longer life. The R7S double-ended connector is the standard for a reason. It gives you a secure, low-resistance connection that stays tight through the constant heating and cooling. No loose contacts. No arcing. And the quartz glass handles rapid on/off cycles better than standard glass, which means fewer surprises and fewer broken lamps out on the shop floor.
What It Feels Like on the Line
On a blow machine, this lamp goes straight to work heating the parison. The infrared energy is focused, so the plastic heats evenly—critical for consistent wall thickness and strength. Its compact size makes it easy to fit into the heating cabinet without a fight. For you, that means a straightforward, drop-in replacement that keeps the line moving. It’s built tough enough for constant vibration and heat, but it still needs a clean mounting surface. Keep it clean, and you avoid hot spots and early burn-out.
**One last thing:**Always double-check the voltage rating (usually 220V–240V or 400V) against your machine’s supply before you wire it up. If the voltage doesn’t match, the lamp won’t stand a chance.
