Burnout Furnace

Perfect Firing for Flawless Castings The Imtex Burnout Furnace is a high-performance kiln designed specifically for the “lost wax” casting cycle. Achieving the correct burnout cycle is the most critical step in preventing casting defects like gas porosity or mold cracking.

Our furnace features an advanced PID (Proportional-Integral-Derivative) Controller, which offers microprocessor-based thermal precision. Unlike standard analog ovens, this system automatically calculates and adjusts power output to maintain your exact target temperature with minimal fluctuation. It is engineered to handle the slow ramp-up required to melt wax safely and the high-temperature soak needed to cure the plaster flask completely.

Key Features

  • PID Digital Accuracy: Microprocessor control ensures temperature stability within ±1°C, preventing “overshoot” that can crack fragile investment molds.

  • Programmable Cycles: (Optional on advanced models) Set multi-step ramp/soak profiles (e.g., rise to 150°C for dewaxing, hold, rise to 750°C for burnout).

  • Uniform Heating: Heating elements are embedded on three or four sides (depending on model) to ensure even heat distribution throughout the chamber.

  • Fume Exhaust System: Integrated vent or chimney port allows wax fumes and steam to escape, preventing carbon buildup inside the chamber.

  • Heavy-Duty Insulation: High-grade ceramic fiber or firebrick insulation retains heat efficiently, reducing electricity consumption and keeping the outer body safe to touch.

  • Vertical/swing Door: Designed for operator safety, directing heat away from the user when opening the hot furnace.

Ideal Applications

  • Wax Burnout: Removing wax from investment flasks prior to gold/silver casting.

  • Resin Curing: Specifically calibrated for casting 3D printed resin patterns (requires specific airflow/ventilation).

  • Enameling: Suitable for high-temperature enamel work on copper or silver.
