Kaya-Cast Jewelry Vacuum Casting Machine | 1500W Melting and Casting 1100°C

Professional integrated jewelry vacuum casting machine combining 1500W melting power and 400W vacuum casting in one unit — reaching 1100°C to melt gold, silver, copper, and alloys while the aviation-grade vacuum hood eliminates air entrapment for clean, high-density castings.

Key Selling Points

• 1500W Melting Power to 1100°C (2012°F) — melts gold, silver, copper, brass, bronze, aluminum, and lead in approximately 48 minutes; suitable for all non-ferrous metals with a melting point below 1100°C
• Integrated Vacuum Casting Chamber — 400W dedicated casting circuit with aviation-grade thick-walled vacuum hood reduces air entrapment during casting, minimizing burrs and surface bubbles in finished pieces
• Accurate Pressure Gauge — real-time chamber pressure monitoring allows precise adjustments for consistent casting surface quality across every pour
• Built-in Fuel Tank with Level Indicator — integrated refueling device with standard reference line for controlled, mess-free refueling during operation
• Two Functions in One Machine — melting furnace and vacuum casting chamber combined in a single compact unit, reducing bench space requirements and workflow steps
• Dual Voltage 110V and 220V — compatible with workshops worldwide, no external converter required

About This Product

The Kaya-Cast HH-CM06 integrates a resistance melting furnace and a vacuum casting chamber into a single bench-top machine, eliminating the need to transfer molten metal between separate units. The 1500W heating element brings the crucible to casting temperature while the vacuum system draws air from the investment mold simultaneously, reducing the window for oxidation and heat loss between melt and pour.

The aviation-grade thick-walled vacuum hood provides a durable, airtight seal over the casting chamber, and the precision pressure gauge allows the operator to monitor and adjust vacuum levels in real time. Suitable for professional jewelry studios, casting houses, and precious metal fabrication workshops working with gold, silver, copper, and non-ferrous alloys up to 1100°C.

Pro Tips

• Verify your metal's melting point before use. This machine has a maximum temperature of 1100°C (2012°F). Gold alloys typically melt between 880–1060°C depending on karat; sterling silver melts at approximately 893°C. Pure platinum at 1768°C exceeds this machine's capacity and must not be attempted.
• Confirm the flask fits the casting chamber before heating. The maximum flask size is 4 x 7 inches (101 x 178 mm). Measure your flask diameter and height before starting the melt cycle. A flask that does not fit cannot be inserted after the metal is at casting temperature.
• Preheat the investment mold to the correct casting temperature before initiating the pour. Pouring molten metal into a cold mold causes thermal shock, premature solidification at the sprue, and incomplete fill. Use a separate flask preheating furnace to bring the mold to the recommended casting temperature before placing it in the casting chamber.
• Check the vacuum hood seal and bell jar for cracks before each session. A compromised seal prevents the chamber from reaching full vacuum, resulting in air entrapment and surface porosity in the finished casting. Replace worn gaskets or a cracked bell jar before use.
• Ensure adequate ventilation during operation. Metal fumes generated during melting are hazardous. Operate in a well-ventilated space or under a fume extraction hood. Always wear heat-resistant gloves and appropriate eye protection throughout the melting and casting process.

Frequently Asked Questions

Can this machine cast platinum?
No. Pure platinum has a melting point of approximately 1768°C, which exceeds this machine's maximum temperature of 1100°C. This machine is suitable for gold alloys, sterling silver, copper, brass, bronze, aluminum, and other non-ferrous metals with a melting point below 1100°C.

What is the maximum flask size the casting chamber can accommodate?
The maximum casting flask size is 4 x 7 inches (101 x 178 mm). The casting chamber measures 140 x 190 mm (5.5" x 7.5") in diameter and height. Measure your flask dimensions carefully before ordering to confirm compatibility.

Does this machine replace a separate vacuum investing machine?
This machine combines melting and vacuum casting in one unit. It is designed for vacuum-assisted casting of molten metal into an investment mold. It is not a standalone vacuum investing machine for degassing investment mix before burnout — a separate vacuum investing machine is recommended for that stage of the casting workflow.

How long does it take to reach casting temperature?
The machine reaches its maximum temperature of 1100°C in approximately 48 minutes from a cold start. Actual melt time depends on the metal type, volume, and ambient temperature. Most gold and silver alloys reach full melt within 30–45 minutes under normal studio conditions.

Is the machine compatible with both 110V and 220V power supplies?
Yes. The machine is available in both 110V and 220V configurations. Select the correct voltage variant for your region at the time of purchase. Do not connect a 110V unit to a 220V supply.
