Import Tips
• Include process diagrams showing non-electric RF heating to distinguish from electric furnaces
• Label with exact max temperature (typically >1400°C for silicon) for proper industrial classification
• Watch for undervaluation pitfalls; provide cost breakdowns separating furnace from accessories
