What this system is.
CXM-HJL vacuum welding furnace is designed for precious metal sintering / melting welding processes. The machine uses induction heating, supports water cooling, and provides built-in protection behavior for safer operation in continuous workshop use.
Where it fits.
Typical scenarios this system is built to serve. Your specific line may overlap more than one.
- 18K / 14K Gold
Boutique and mid-volume gold casting where color uniformity and porosity rate are the bottleneck.
- Sterling Silver
Silver jewelry runs where oxidation control and clean pour geometry define the finishing workload downstream.
- Filigree & Fine Detail
Thin-wall pieces where the fill pressure, grain refinement, and surface fidelity have to be dialed in together.
- Rapid Recipe Switching
Lines running multiple alloys or SKU variants in the same day. Stored programs keep handoff-to-cast stable.
Defects this system addresses.
How the architecture of the machine maps onto the failure modes most common in jewelry casting production.
- Porosity & gas inclusions
Vacuum chamber evacuation before pour, with pressure-assisted fill and secondary vibration to collapse micro-voids before the front solidifies.
- Cold-shut & incomplete fill
Positive pressure during fill keeps the front moving through thin walls; recipe-locked thermal profile prevents the temperature drop that causes shorts.
- Color unevenness & segregation
In-chamber melting eliminates the melt-to-cast handoff step where most segregation and oxidation is introduced. One chamber, one thermal envelope.
- Batch-to-batch inconsistency
Stored programs lock the full sequence — temperature ramp, pressure window, vibration timing — so operator judgement isn't re-introduced each run.
- Operator-dependent quality
Digital recipe control removes the places where tacit know-how gets lost on a shift change. The workflow holds, even when the person changes.
Lead time, install, warranty.
