Stop Wasting Energy on Your Glass Annealing
Let’s be honest: annealing is usually the biggest energy hog in the entire production line. It’s frustrating to watch those power bills climb just because you’re heating up a massive oven volume when you only actually care about the glass itself. That’s why we built our infrared lamps. Instead of heating the air around the piece, these focus the heat right where it needs to go. Getting the heat in fast We designed these lamps to pack a punch. Because they use short-wave infrared, the energy actually sinks into the glass surface faster. For you, that means your pieces spend less time sitting around (shorter dwell time), which keeps things moving. Just a heads-up: if you’re using the high-wattage tubes, double-check your electrical panels. Those startup voltage spikes can be brutal. It’s worth checking your contactor ratings now so you aren’t dealing with a burnout later. Built to take a beating We use high-purity quartz for the envelopes because these things live in a brutal, high-heat environment. The filaments are tuned to a specific frequency that glass actually “likes” to absorb. No wasted energy, no guesswork. Plus, we used standard connectors. If a lamp blows, you just pop it out and drop a new one in. You won’t have to spend your afternoon rewiring the whole rig. The trade-off Switching to IR is great for your wallet and it saves a ton of floor space. But there is a catch: you have to be precise. These lamps are intense. If they’re too close to the glass, you’ll get hot spots or—even worse—thermal shock. To keep things steady, we suggest pairing the lamps with a fast-response thermocouple and a PID controller. It keeps the temperature locked in, so you hit that sweet spot for annealing without overshooting and throwing money away.
