Large High Vacuum Melting Furnace

Boutique and mid-volume gold casting where color uniformity and porosity rate are the bottleneck.

Silver jewelry runs where oxidation control and clean pour geometry define the finishing workload downstream.

Thin-wall pieces where the fill pressure, grain refinement, and surface fidelity have to be dialed in together.

Lines running multiple alloys or SKU variants in the same day. Stored programs keep handoff-to-cast stable.

Vacuum chamber evacuation before pour, with pressure-assisted fill and secondary vibration to collapse micro-voids before the front solidifies.

Positive pressure during fill keeps the front moving through thin walls; recipe-locked thermal profile prevents the temperature drop that causes shorts.

In-chamber melting eliminates the melt-to-cast handoff step where most segregation and oxidation is introduced. One chamber, one thermal envelope.

Stored programs lock the full sequence — temperature ramp, pressure window, vibration timing — so operator judgement isn't re-introduced each run.

Digital recipe control removes the places where tacit know-how gets lost on a shift change. The workflow holds, even when the person changes.
