OEM service pet blowing machine heat lamp 420mm 220vac 1500w halogen bulb

Introduction

We built this 420mm halogen heat lamp as a dedicated OEM piece for PET blowing machines. It runs on 220VAC at 1500W, and it throws down steady, high-density heat exactly where the preform needs it. If you’re looking for a drop-in replacement or a private-label heating module, this one was engineered to keep up with the rhythm of blow molding—no fuss, just the right heat, cycle after cycle.

Technical Deep-Dive

The 420mm length gives you the right spread of radiant heat, covering the neck and body of the preform without overshooting the parison. At 1500W on 220VAC, the current draw is predictable, so sizing your wiring and terminals is straightforward. No guesswork. That power density is chosen to bring PET up to the ideal stretch temperature fast, so your cycle time stays consistent.

Material & Design

Inside, the halogen element burns hot and clean, sealed in a quartz envelope that handles rapid temperature swings without cracking. The shortwave output focuses the energy where it matters, and the reflector coating pushes heat forward—less waste, more punch. It uses an R7s double-ended base, so it locks in straight and stays aligned in the reflector. No wobble. No drift. Just a solid, secure fit.

Application & Benefits

On a PET blowing machine, you need heat that comes on quickly, holds steady, and keeps working despite the shop-floor vibration. This lamp delivers on all three, and it installs as a simple swap-in. One thing to keep in mind: with 1500W of power, you do need adequate airflow and thermal management around the lamp. If your cooling is undersized, you can run into overheating and shorten the lamp life. Make sure your machine’s cooling matches the heat load.
