A reliable preheating furnace for dental casting rings
In a dental laboratory, investment ring preheating is a critical step for achieving consistent casting results and reducing defects caused by thermal variations.
The Mestra HP50 furnace provides a professional solution thanks to its controlled heating process, generous chamber capacity and programmable thermal cycles adapted to dental laboratory workflows.
Key advantages
- Robust ceramic chamber for excellent thermal stability.
- 4 integrated heating elements for homogeneous heating.
- Maximum temperature up to 1100 °C.
- 20 programmable memories for recurring workflows.
- 3 programmable heating stages.
- Adjustable heating ramp in °C/min.
- Delayed start function for optimized laboratory scheduling.
- Acoustic signal at the end of the cycle.
- Safety system with door opening detection.
Dental laboratory applications
- Preheating investment rings for dental alloy casting.
- Fixed and removable metal prosthetic workflows.
- Thermal management of dental investment materials.
- Preparation of rings before cobalt-chromium casting.
- Consistent daily production cycles in dental laboratories.
- Improved workflow organization thanks to delayed start.
Heating control and programmable thermal cycles
The Mestra HP50 burnout furnace allows precise thermal cycle programming with multiple stages, adjustable heating ramps and holding times adapted to professional dental laboratory protocols.
This electronic management system helps maintain reproducible results, reduce thermal stress and optimize heating cycles according to the investment material used.
Quick operating guide
- Select an existing program or create a new cycle.
- Adjust heating stages, ramps and holding times.
- Place the casting rings on the supplied ceramic tray.
- Start the cycle or use the delayed start function.
- Wait for the acoustic end-of-cycle signal.
- Handle hot rings using suitable pliers and protective equipment.
Laboratory recommendation
To preserve the ceramic chamber and maintain homogeneous heating, it is recommended to avoid overloading the furnace, leave sufficient space between the rings and follow the heating ramps recommended by investment material manufacturers.
Regular inspection of the pyrometric probe and smoke outlet also helps secure the thermal cycles and reduce production downtime.
