Getting Your SACMI Lamps to Actually Keep Up

If you’re running a SACMI rotary blow molding machine, you know the pace is relentless. You have a tiny window of time to get that PET preform heated just right. When your lamps are sluggish or the temperature starts bouncing around, you can see it in the bottles immediately. You get those annoying thin walls or that cloudy, pearlescent look that makes a batch look amateur. It’s frustrating. The trick to a fast start To fix this, we look at the physics of the filament and the quartz. We use high-wattage density lamps because they hit operating temperature in milliseconds. The real challenge? Thermal shock. We build these modules to handle the constant, rapid on-off clicking of the PLC without the filament just snapping. It’s about durability under pressure. Fitting them into your SACMI setup We designed these to be simple drop-in replacements. They match the original oven rack footprints exactly—same length, same diameter. No hacking or modifying your equipment. We also use a specific type of quartz glass. It lets shortwave IR radiation fly right through instead of soaking it up. This means the heat goes straight into the plastic, not into the air inside the oven. Now, here is the catch. High-voltage setups give you the heat density you need for high-speed lines, but they run hot. If your cooling fans are clogged or just too small, you’ll bake your reflectors and kill your lamps early. Keep those fans clean. Setting them up for the long haul We stick to industry-standard connectors so you can get them wired up fast during a teardown. A pro tip: make sure they are seated perfectly in the socket. A loose fit is the fastest way to burn out a terminal. We test every single module for voltage stability. Why? Because nothing is worse than that “cold start” lag that ruins the first few hundred bottles of a run. With these, when the machine asks for heat, the lamps answer immediately.

No-Fuss Heater Modules for Sidel SBO and Matrix Lines

Heating PET preforms is a bit of a balancing act. You need enough infrared energy to get the body to that sweet spot—the glass transition temperature—but if you aren’t careful, you’ll torch the neck of the bottle. It’s a tight line to walk. That’s why we build our PETC heater modules specifically for Sidel systems. Whether you’re still running the old-school SBO lines or you’ve moved up to the Matrix series, we’ve got you covered.

On the blow molding line, the heating tunnel is where uptime and bottle quality live or die. Preforms running cool give you weak biaxial stretch, crystalline haze, and scrap climbing fast. Run them too hot, and you’re dealing with scorched PET, brittle necks, and a heater that keeps tripping the line. We built our infrared radiators to kill that seesaw and give you repeatable heat control, whether your machine is a Sidel SBO, Krones Contiform, SIPA SBO, Husky, SACMI, or Nissei ASB. The technical heart of it comes down to the emitter choice. For PET preform heating, short-wave quartz infrared emitters deliver fast response and tight control across the tunnel, with a spectral output matched to PET absorption. We offer halogen and quartz options in standard voltages, built around the R7s connector you see in most blow molding ovens. Power density is sized to your preform weight and cycle, so you get the right heat without overshooting the setpoint. Output stays stable over 5,000+ hours, with drift under 5%, and the geometry drops into OEM lamp sockets and mounting brackets. Here is why it works in practice: the right infrared radiator shortens the heating curve and tightens temperature spread across the preform body. That means faster cycles, fewer rejects from uneven stretch, and less downtime chasing lamp changes. Energy use drops because the emitters heat on demand and hold setpoint without wild cycling. For PET and PETC preforms, consistent surface-to-core heat improves molecular orientation and builds a stronger bottle, even when you push higher line speeds. One thing to keep straight: infrared heating is line-of-sight. You have to hold preform spacing and rotation so every preform sees the same flux. If conveyor speed is varying, you need to retune the power zones. Also, match the lamp length to the heating tunnel width—undersized lamps create cold zones, oversized ones waste energy and can overheat the oven frame. Give us your blow molder model and preform geometry, and we’ll spec the exact wattage, length, and connector so it drops in and runs.
