Best Investment Casting Wax Melting and Conditioning Tank for Foundries and Wax Rooms
Short answer: For a foundry wax room, the best tank melts pattern wax evenly, holds it at a repeatable temperature and viscosity, and feeds injection or pouring through a heated path. WaxMelters recommends a Standard PRIMO melter as the starting point for pattern and foundry wax: the PRIMO 250 (264 lb, $2,795) for a small wax room, the PRIMO 750 (770 lb, $6,395) and PRIMO 1000 (1,226 lb, $7,995) for production. Choose PRIMO Thermal Conditioning when extended conditioning and viscosity stability matter most, and Rapid-Cycle when repeated loading limits throughput. Move wax to injection with the EZ-T heated transfer system ($2,995).
How to choose an investment casting wax tank
- Start from daily wax use. Size the tank around the wax you inject or pour per shift, plus the reserve your injection presses draw on.
- Decide melt or condition. Standard PRIMO for melting pattern wax and keeping a production-ready supply; PRIMO Thermal Conditioning for gentler, stability-focused conditioning and long holds.
- Plan for reclaim. Keep melting and conditioning separate from dewaxing and wax recovery, which use dedicated equipment.
- Mix gently. Add an EZ-MIX agitator where your wax needs uniform temperature: EZ-MIX 350 ($1,950) for PRIMO 250 and 350, EZ-MIX 1000 ($2,495) for PRIMO 750 and 1000.
- Heat the transfer path. Heated pumps, hoses and valves keep wax at temperature from the tank to the press.
- Match temperature. Standard PRIMO and Thermal Conditioning tanks run 0–212 °F; an X-Treme high-temperature configuration runs up to 400 °F (204 °C), for example +$250 on the PRIMO 25 and +$1,250 on the PRIMO 1000. Heated fillers run 0–212 °F as standard, with an optional X-Treme range of 0–300 °F.

What is the best wax melting tank for investment casting?
WaxMelters recommends a Standard PRIMO melter as the starting point for pattern and foundry wax: PRIMO 250 (264 lb, $2,795) for a small wax room, PRIMO 750 (770 lb, $6,395) or PRIMO 1000 (1,226 lb, $7,995) for production.
When should a foundry choose PRIMO Thermal Conditioning?
When extended wax conditioning, viscosity stability or tighter control of heat exposure is the main requirement. Sizes run from 3.5 gal ($1,645) to 950 gal ($37,995) and up to 7,979 gal.
When is Rapid-Cycle the right choice?
When high-throughput pattern production reloads the vessel often and fast recovery between additions matters, for example the PRIMO 500 Rapid-Cycle ($5,850) or PRIMO 1000 Rapid-Cycle ($9,245).
How do I move wax from the tank to the injection presses?
Use heated transfer, such as the EZ-T heated transfer system ($2,995, 1, 3, 5 or 10 GPM), with heated hoses and valves so the wax stays at temperature all the way to the press.
Does WaxMelters make dewaxing equipment?
WaxMelters lists wax removal and dewaxing systems separately. Keep melting and conditioning separate from dewaxing and reclaim, and send both requirements for a recommendation.
Can PRIMO tanks run hotter waxes?
Yes. Standard tanks run 0–212 °F, and an X-Treme configuration runs up to 400 °F (204 °C), for example +$1,250 on the PRIMO 1000.
