On a high-volume tablet glass line, the bending station is where the schedule hits the glass. If the heater can’t keep up on temperature, your cycles drag. If the field isn’t even, you pay for it later as warp, stress marks, or fractures after tempering. We built the tablet glass bending heater to cut that compromise out. What matters, technically We run short-wave quartz infrared elements because they dump energy straight into the glass surface—minimal convection delay. Response is immediate: the heater jumps from ambient to 650°C in 8–12 seconds, so the bending window opens fast without the press idling. Across the active face, temperature uniformity sits at ±3°C at 600°C. That keeps thermal stress predictable and keeps optical distortion out of the finished tablet. Power density is tuned at 45–60 W/cm² to match typical glass thicknesses and coatings, so you get fast heat-through without scorching low-emissivity layers. The module is rated for 480 V three-phase, and the terminal layout and mounting footprint are laid out as a drop-in fit for standard bending presses. Why it works in tablet glass bending Tablet glass bending is all about timing. You need repeatable temperature, cycle after cycle, to hold shape tolerance and keep the tempering line fed. With the fast ramp and tight uniformity, you shorten dwell, cut scrap from thermal shock, and steady throughput. Energy use drops because the heater spends less time in warm-up and more time in stable operation, and the quartz envelope holds up under repeated thermal cycling. Here are the practical details This is a line-voltage heater, not a low-voltage cartridge, so confirm your press wiring and contactors can handle the inrush load. Surface temperature can exceed 700°C during operation, so clearance and shielding are mandatory. For glass with low-e coatings, set the target temperature at the coating limit and tune cycle time. The same fast response that helps yield can overshoot if the setpoint is too aggressive.
