FAQ
Click to open a question.
How do I program the firing stages and heating ramps?
The control panel lets you define up to three stages per program.
First, set the target temperature for each stage to define the plateau.
Then enter the ramp in degrees per minute to control the temperature rise.
Define the holding time to stabilise the ring and investment throughout.
You can store up to twenty programs for recurring lab protocols.
The delayed start function helps you anticipate firing cycles and optimise your casting schedule.
An acoustic signal confirms the end of the cycle for safe, user-friendly handling.
What best practices help preserve the HP25 ceramic muffle?
Avoid thermal shock by following the recommended ramps for each cycle.
Use the supplied ceramic tray to stabilise the rings and distribute the load evenly.
Do not overload the chamber and keep free space for homogeneous hot air circulation.
Regularly check the condition of the thermocouple and replace it if worn.
Gently clean projections after complete cooling to protect the chamber walls.
Ensure proper ventilation via the 38 mm exhaust outlet.
Keep a log of firing cycles to plan preventive maintenance and reduce downtime.
Is the furnace suitable for series work and different alloy types?
Yes, its capacity and multi-stage programming provide great flexibility in daily use.
The four heating elements ensure homogeneous heat distribution for repeated series runs.
Ramps in °C/min allow fine adjustment of firing curves according to the investment used.
Storing twenty programs simplifies switching between alloys or ring sizes.
Built-in safety (door detection and end-of-cycle signal) supports high daily throughput.
The insulation and chamber stability promote excellent reproducibility of results.
Always follow the alloy and investment manufacturers’ recommendations to ensure full compatibility between materials and process.
Key takeaway
The Mestra HP50 cylinder furnace is designed for preheating dental investment materials, offering precise control, 4.8 L capacity, integrated safety features and fully programmable firing cycles.
