The CDOCAST platinum melting furnace series is designed for platinum, palladium and compatible high-temperature metals. This induction platinum melting furnace range includes standard CDO-FM16 to CDO-FM20 models for 1–10 kg platinum batches, while larger tilting configurations are available for customized production requirements.
Core features for high-temperature precious metal melting and controlled production.
IGBT induction power transfers energy directly to the metal charge. Actual process temperature depends on the machine, crucible, metal and operating settings.
Induction heating creates melt movement that supports more uniform temperature and alloy distribution before pouring.
The integrated pump connects to the cooling-water circuit. A suitable industrial chiller is recommended for frequent or extended production.
An infrared pyrometer can be configured for non-contact monitoring. Surface condition and dross can affect measurement accuracy.
Choose the furnace structure according to capacity, crucible handling, mold position and production workflow.
Integrated stationary configuration for platinum and palladium batches from 1 kg to 15 kg. Standard CDO-FM models cover 1 kg, 3 kg, 5 kg, 8 kg and 10 kg platinum capacities, while the 15 kg version is supplied as a customized configuration.

The temperatures above are equipment and crucible configuration limits from the current model table, not guaranteed molten-metal temperatures for every process. Actual results depend on the model, crucible material, metal, batch weight, power supply, cooling, measurement method and operating settings. Confirm the required metal and capacity before ordering.
Crucible material affects temperature capability, service life, cost and operating procedure.
The standard table lists up to 2000°C with a quartz crucible, but quartz service life can decrease rapidly during repeated high-temperature platinum operation.
The current model table lists up to 2600°C with a zirconia crucible. This option offers a wider temperature margin for demanding platinum, palladium and rhodium processes.
High-temperature melting requires correctly sized utilities and trained operation.

CDO-FM16 is the standard 1 kg platinum melting furnace. CDO-FM18 and CDO-FM20 cover maximum 5 kg and 10 kg platinum batches. Larger 15 kg and 30 kg platinum induction furnace requirements are customized and should not be selected only from the standard table.
Final selection must also account for crucible material, pouring method and site utilities.

Answers about temperature, melting time, electromagnetic stirring, furnace structure, voltage, cooling, warranty and crucible selection.
The platinum melting furnace can reach up to 2000°C with a quartz crucible and up to 2600°C with a zirconia crucible. It can be configured for platinum, palladium, rhodium and compatible high-temperature metals such as steel and stainless steel. The appropriate crucible and operating settings depend on the metal and process.
The CDO-FM16 typically melts a 1 kg platinum batch in approximately 1–3 minutes. Actual melting time varies with the starting temperature, charge form, power supply, crucible condition, cooling and operating settings.
Induction heating naturally creates electromagnetic stirring in the molten metal. This circulation helps distribute heat and alloying elements more uniformly, reducing segregation and supporting more consistent platinum and precious-metal alloy preparation.
With an integrated stationary model, trained personnel remove the crucible using suitable tongs and pour into a separate mold. A manual tilting platinum furnace rotates toward the prepared mold for controlled direct pouring and is commonly selected for larger batches. The tilting structure can also help preheat the pouring area and reduce premature solidification near the spout.
The standard specification is three-phase 380 V, 50/60 Hz. Alternative electrical configurations such as 220 V or 440 V may be available according to the model and local power supply. Confirm the required voltage, phase and frequency with CDOCAST before manufacturing.
The furnace includes a built-in water pump but still requires a correctly sized cooling-water circuit. A water tank may be suitable for short or intermittent operation, while an external industrial water chiller is recommended for frequent or continuous high-temperature production.
CDOCAST provides a two-year warranty for the platinum melting furnace. Warranty coverage applies to eligible quality-related faults under the agreed sales terms; consumables, incorrect operation and normal wear are not treated as manufacturing defects. Confirm the detailed warranty scope with the quotation or contract.
The furnace can be equipped with an optional infrared pyrometer for non-contact monitoring of the molten-metal surface. Its accuracy depends on the measurement range, emissivity, surface condition and process setup. Dross or scum can affect the reading, so the pyrometer should not be used as the only process-control reference when the surface is heavily contaminated.
Yes. Quartz and zirconia crucibles are consumable parts, and their service life depends on the metal, working temperature, heating cycle and handling method. A quartz crucible may be reused for several cycles under suitable conditions, but no fixed lifespan can be guaranteed for every process. Replacement crucibles are available in multiple capacities.
Yes. A zirconia crucible provides a wider high-temperature margin and strong chemical stability, making it suitable for demanding platinum, palladium and rhodium melting, but it costs more and normally requires careful preheating and handling. A quartz crucible is more economical and has good thermal-shock resistance, but its service life is shorter at sustained platinum-melting temperatures. Select the crucible according to the metal, purity requirement, operating temperature and production schedule.
