When assessing price, you must look beyond the sticker cost and evaluate heating element types (Short-wave, Medium-wave, or Long-wave), as short-wave IR offers the fastest curing but at a higher cost. Ensure the oven features PID Temperature Controllers for precision within ±1°C and high-density rock wool insulation (at least 100mm thickness) to minimize heat loss. The conveyor system quality, specifically the motor brand and belt material (e.g., Teflon or Stainless Steel), significantly impacts the long-term valuation.
