800°C Jewellery Casting Flask Preheating Furnace – 1500W
The Tooltos 800°C Jewellery Casting Flask Preheating Furnace is designed for jewellers who require a compact and straightforward method of heating investment flasks before casting.
After the wax burnout process has been completed in suitable burnout equipment, the flask can be transferred to this furnace and brought to the temperature required by the investment and casting process.
The 1500W resistance-wire heating system reaches a maximum temperature of 800°C in approximately 30 minutes under normal operating conditions. Actual heating time may vary depending on room temperature, electrical supply, load size and operating conditions.
A digital PID controller allows the user to set and monitor the chamber temperature. The internal chamber measures 150 × 150 × 200 mm and accommodates cylindrical casting flasks up to approximately Ø102 × 178 mm.
Its compact footprint makes it suitable for independent jewellery studios, educational workshops, jewellery schools and small casting facilities where a full-size industrial furnace is not required.
SUITABLE APPLICATIONS
• Preheating investment flasks before jewellery casting
• Holding previously burned-out flasks at casting temperature
• Preparing flasks for vacuum casting
• Preparing flasks for centrifugal casting
• Small jewellery studios and casting workshops
• Jewellery schools and training environments

NOT SUITABLE FOR
• Wax burnout or wax removal
• Burning resin or 3D-printed patterns out of investment moulds
• Melting gold, silver, copper or other metals
• Enamelling, ceramics or glass work unless independently confirmed as compatible
• Food preparation or domestic heating application

BASIC OPERATING GUIDANCE
Position the furnace on a stable, level and non-combustible work surface.
Ensure that the selected machine voltage matches the local electrical supply.
Complete the wax burnout process separately using suitable burnout equipment.
Place the previously burned-out flask inside the chamber using appropriate protective equipment.
Close the furnace door and set the required temperature using the digital controller.
Allow the chamber and flask to reach the temperature specified by the investment material or casting process.
Remove the hot flask using suitable protective gloves and handling tongs.
Switch off the furnace after use and allow it to cool naturally before cleaning, moving or storing it.
Always follow the temperature schedule and safety instructions provided by the investment material manufacturer.
ELECTRICAL COMPATIBILITY
This product is available in 110V and 220V versions.
Before ordering, confirm that the selected version is compatible with the voltage, frequency, socket and electrical circuit used in your workshop.
European and UK customers should check compatibility with their local mains supply before purchase. A plug adapter changes the plug format only and does not convert voltage.
SAFETY INFORMATION
• Use only in a suitable workshop or professional working environment.
• Install the furnace on a heat-resistant, non-combustible surface.
• Maintain adequate clearance around the machine.
• Operate in a well-ventilated area.
• Keep combustible materials away from the furnace.
• Wear suitable protective gloves, eye protection and workshop clothing.
• Use appropriate tongs when handling hot flasks.
• Do not touch the chamber, door or metal surfaces while the furnace is hot.
• Do not leave the furnace unattended during operation.
• Do not exceed the maximum rated temperature.
• Disconnect the power supply and allow the furnace to cool completely before inspection or maintenance.
• Installation and electrical inspection should be carried out by a qualified person where required by local regulations.

FREQUENTLY ASKED QUESTIONS
Can this furnace be used for wax burnout?
No. This model is designed to preheat investment flasks after the wax burnout process has already been completed. It must not be used to remove wax, resin or printed patterns from investment moulds.
Can it melt gold or silver?
No. This is not a metal melting furnace. Gold, silver and other metals must be melted in a dedicated jewellery melting furnace.
What is the maximum temperature?
The maximum rated temperature is 800°C.
How long does it take to reach 800°C?
The furnace reaches 800°C in approximately 30 minutes under normal operating conditions. Heating time may vary depending on the load, ambient temperature and electrical supply.
What is the largest flask that will fit?
The internal chamber measures 150 × 150 × 200 mm and accommodates commonly used cylindrical flasks up to approximately Ø102 × 178 mm, equivalent to approximately 4 × 7 inches.
Can it be used with vacuum and centrifugal casting systems?
Yes. It can be used to preheat previously burned-out investment flasks before transferring them to a compatible vacuum or centrifugal casting machine.
Does it have programmable ramp and hold stages?
This model uses a digital PID temperature controller for setting and monitoring temperature. It should not be described as a multi-stage programmable burnout furnace unless the supplied controller is specifically confirmed to support ramp-and-hold programming.
Why can I not change the temperature when first using the furnace?
A factory temperature lock may be enabled. Refer to the supplied operating instructions or contact Tooltos support for the correct unlocking procedure for your controller version.
Which voltage should I select?
Select the version that matches the electrical supply in your workshop. Check the machine rating, local voltage, socket type and circuit capacity before connecting the furnace.
