KAYA CAST HH-CM06 Jewelry Vacuum Casting and Melting Machine with Built-In Pump
About This Vacuum Casting Machine
This integrated jewellery casting machine combines metal melting, investment degassing and vacuum-assisted casting in one compact workstation.
Its built-in 2L vacuum pump removes the need for an external pump, making it a practical choice for small-studio lost-wax workflows. The 1500W melting system reaches up to 1100°C for compatible jewellery metals and alloys. A separate burnout furnace is required and is not included.
Voltage Selection Guide
| Check Before Purchase | What to Confirm |
|---|---|
| Supply voltage | Select the 110V or 220V version that matches the electrical supply at your installation location. Automatic dual-voltage operation is not stated. |
| Rating label | Confirm the voltage shown on the machine's rating label before connecting power. |
| Vacuum oil | Vacuum pump oil is not included. Add suitable oil before first use and check the level as part of routine setup. |
| Burnout furnace | A separate burnout furnace is required to prepare flasks before casting. This machine does not perform wax burnout. |
| Flask size | Maximum flask size is 4 x 7 in (101.6 x 177.8 mm). Confirm your flask dimensions before purchase. |
Best For / Not For
| Best For | Not For |
|---|---|
| Small jewellery studios doing lost-wax casting | Continuous mass production |
| Casting rings, pendants, charms and small batches | Platinum casting |

Pro Tips
- Add vacuum oil before first use. Check the oil level as part of routine setup and never operate the pump without oil.
- Confirm voltage before ordering. Choose either the 110V or 220V version to match your local electrical supply — do not assume dual-voltage capability.
- Follow investment and alloy manufacturer instructions. Match flask preparation, burnout schedule and casting temperature to the specific materials you are using.
- Keep sealing surfaces clean. Wipe the hood edge, vacuum table and casting chamber rim after each session to maintain a reliable vacuum seal.
- Use appropriate PPE. Wear eye, face, hand and body protection and handle hot crucibles and flasks only with purpose-made tools.
FAQ
Does the machine require an external vacuum pump?
No. A 2L vacuum pump is built into the machine, so no external pump is needed.
Is vacuum oil included?
No. Suitable vacuum oil must be purchased separately and added before first use. Do not operate the pump without oil.
Does it replace a burnout furnace?
No. A separate burnout furnace is required to remove wax and prepare the flask before casting. This machine does not perform burnout.
Which metals can it melt?
It is intended for compatible gold, silver, copper, brass, bronze, aluminium and jewellery alloys with melting points below 1100°C. It is not suitable for platinum, stainless steel or titanium.
Can I connect it to either 110V or 220V?
The product is offered in separate 110V and 220V versions. Select the version that matches your installation site's electrical supply. Automatic dual-voltage operation is not stated.
