Graphite and carbon engineering for foundry: ESGRAF advises on material selection and application support across Mexico and the Americas.

Crucibles, pouring spouts, stirrers, additives and lubricants for metal foundry.

Foundry work concentrates many graphite uses: crucibles, ingot molds, pouring spouts, lances, stirrers, additives and mold-release lubricants. Each part balances purity, density and mechanical strength differently.

ESGRAF combines inventory, machining and application advice so the consumable matches the metal and plant cycle across Mexico and the Americas.

## Applications with ESGRAF

In ferrous and non-ferrous foundries, graphite and carbon typically support:

- **Containment and pouring** — crucibles, ingot molds, spouts and runners.
- **Metal treatment** — degassing lances, fluxing tubes and stirring bars.
- **Release and lubrication** — additives, lubricating paints and dry lubricants on molds and hot surfaces.
- **Process tooling** — plates, plugs and machined parts that must hold geometry under thermal shock.

The goal is longer life, stable dimensions and reliable supply without contaminating the metal or stopping the line.

## Recommended product families

- [Isostatic graphite](/en/materials/technical-graphite/high-density) — demanding geometries and higher uniformity.
- [Extruded graphite](/en/materials/technical-graphite/extruded) — tubes, bars and profiles for lances and sleeves.
- [Crucibles and molds](/en/materials/technical-graphite/high-density) — machined parts for melting and casting.
- [Electrodes](/en/materials/technical-graphite/edm) — when electrical contact or EDM is tied to the tooling.

We also review additives and lubricants when the process needs them, based on metal and application method.

## Frequently asked questions

### Which graphite parts are most common in foundry?

Crucibles, ingot molds, pouring spouts, lances, stirrers and contact plates or molds. The exact list depends on the metal (aluminum, copper, iron, precious metals) and furnace or ladle setup.

### How do you choose the right grade?

We review alloy, temperature, atmosphere, geometry, mechanical load and expected life. A current grade reference or a failed part speeds up equivalence and recommendation.

### Can you machine parts from our drawing?

Yes. ESGRAF CNC-machines components from drawings, dimensioned PDFs or samples. Share critical tolerances, holes and quantity for a technical quote review.

### Is graphite used for mold release?

Yes — as dry lubricants, lubricating paints or additives depending on the process. Selection depends on temperature, application method and whether contact is with metal or the mold.

### Do you support foundries across Mexico?

Yes. Start a [quote](/quote) or reach [contact](/contact) with process details.
