Frequently asked questions

From ESGRAF. We stock and CNC-machine graphite in García, N.L. (Monterrey) with shipments across Mexico and the Americas. We quote technical graphite, powders, lubricants, and made-to-print parts.

At the ESGRAF plant in García, N.L. (metro area): Triángulos 140, Arco Vial, ZIP 66023. Local inventory, cutting, and CNC parts with delivery in the metro area and nationwide.

Synthetic graphite (isostatic, molded, extruded, vibro-molded), impregnated grades, natural graphite, powders and granules, carbon felts, flexible graphite (GRAFOIL), and ESGRAF’s own graphite lubricants and coatings.

In Mexican industrial practice, “isomolded” is often used as a commercial synonym for isostatic graphite (CIP). Both point to material with more uniform properties than extruded or conventional molded grades. Always confirm density, grain size, and application with the supplier.

Extruded graphite often fits profiles, bars, and applications where anisotropy is acceptable and cost per volume matters. Isostatic (isomolded) is chosen when you need more uniformity, fine grain, and tighter CNC tolerances (EDM, precision crucibles, critical parts).

It depends on the application: lubrication, foundry, release agents, or additives need different ranges. Share the process, target particle size, and whether you need natural or synthetic; we’ll point you to the right powders-and-granules family.

Yes. We work with original and equivalent grades. We compare density, grain size, porosity, and process conditions before recommending a local substitute or continuity with the reference brand.

Yes. We machine graphite and carbon-graphite parts from drawings or samples, with typical tolerances down to ±0.02 in depending on geometry and grade.

Catalog products: 3–7 days. Custom machined parts: 7–15 days depending on complexity, material, and finish. Special projects get a dedicated schedule.

In the Monterrey metro area, stock material is often coordinated within days. Nationwide, catalog items typically ship in 3–7 days; CNC parts 7–15 days depending on geometry and grade. Confirm your target date with sales.

Yes. We stock industrial and high-purity isostatic graphite for EDM, precision components, molds, and vacuum or controlled-atmosphere applications.

Yes. We supply and apply graphited coatings and paints (e.g. GRAFOTERM, GRAFICOAT) that protect graphite and refractory surfaces in furnaces and oxidizing environments, extending component life.

Yes. Our specialists recommend grade, format, and process based on temperature, atmosphere, load, speed, chemical media, and your part geometry.

Yes. Our core market is Mexico and the Americas; we also ship to South America and other countries depending on the project and logistics.

We operate an ISO 9001 quality management system with lot-level traceability on supplied materials and components.

Graphite is self-lubricating dry, thermally stable, and compatible with vacuum or atmospheres where oils and greases fail or contaminate. Ideal for bushings, spacers, and rotary inserts.

OD × ID × length (or drawing), quantity, temperature, atmosphere, load/speed, and current or preferred grade. With that we recommend isostatic, extruded, or carbon-graphite.

Fine detail and surface finish favor fine-grain, low-porosity isostatic grades. Faster stock removal uses coarser grades. We also offer impregnated blanks when lower wear or pore sealing is required.

Impregnation reduces open porosity, improves sealing, and can increase wear resistance. Resin is common for seals and EDM; metal impregnation adds conductivity and hardness for demanding mechanical uses.

Yes. Graphite plates keep a low dry friction coefficient and dimensional stability where liquid lubricants degrade. Grade (vibro-molded, isostatic, etc.) is chosen by load and atmosphere.

Depending on metal, temperature, and thermal cycle we recommend vibro-molded, molded, or isostatic grades. We supply crucibles, ingot molds, sintering molds, and pouring spouts as catalog or custom parts.

Yes. We machine graphite degassing lances and stirring elements for non-ferrous metals, selecting grades for thermal resistance and shock.

Yes. We supply carbon-graphite materials and formats (bars, machined parts) for pantographs, electrical contacts, and grounding, graded by current, speed, and environment.

Yes. We make graphite molds for exothermic welding using molded or isostatic grades based on reuse cycles and joint geometry.

Faces and rings are typically machined from carbon-graphite or impregnated graphite for sealing and controlled wear. We complement with GRAFOIL for monoblock gaskets and packing.

Yes. Flexible GRAFOIL graphite withstands high temperatures, sealing flanges and monoblocks where elastomers fail. We cut and supply sheets, rings, and custom gaskets.

Soft felt for flexible liners and conformable insulation; rigid felt for panels and stable structures. Choice depends on max temperature, atmosphere (vacuum, inert), and thermal cycle.

With graphited coatings such as GRAFOTERM and GRAFICOAT that reduce slag/metal sticking, provide dry lubrication, and limit oxidation on rotary kiln tracks and refractory channels.

Yes. Isostatic graphite provides surface finish, thermal conductivity, and dimensional stability for molds, tongs, and float-glass fenders.

Depending on recarburization, slag, or conductivity needs we recommend coke, synthetic, or amorphous graphite in controlled particle sizes. Grades also exist for mortars, pigmentation, and drilling muds.

Yes. Synthetic or flake powders improve electrical conductivity and, in lubricant formulations, reduce friction in plastics and coatings. Particle size and purity are matched to the resin system.

When temperatures are high, dry starts occur, dust/moisture is present, or oil may evaporate. The graphite film remains as residual solid lubrication on chains, guides, shafts, and open mechanisms.

LUBRICHAIN and GRAFOLUB form an adherent film with graphite microbeads for chains in ovens, paint lines, mining, and logistics. GRAFOGREASE covers grease points that need graphited grease.

GRAFICOAT and oil-based suspensions cut metal-to-metal friction on dies; GRAFOGREASE/GRAFICOAT protect press pistons. Choice depends on temperature, cycle, and application method (brush, spray).

Yes. Graphited greases and oils for fifth wheels, agricultural machinery, rail, and equipment exposed to dust, load, and moisture where a solid film matters.

Yes. Lines such as LUBRISEED and tortilla-equipment lubricants target grain/seed handling and industrial bakery equipment; confirm food-contact compatibility for the contact point.

GRAFOLUB is a dual-action graphited oil (liquid + solid). It leaves a graphite-microbead film on shafts, bushings, chains, and open gears when conventional oil evaporates or degrades.

Use graphited grease at grease points, larger clearances, or wherever lubricant must stay put. Oil (GRAFOLUB) flows better in centralized systems, chains, and continuously accessed surfaces.

It is a dry graphited coating/lubricant: it forms an adherent film on metal and refractories for sliding, release, and protection.

Depending on the product: brush, roller, spray, drip, or centralized system. Shake suspensions thoroughly; clean degraded grease and dust from the surface. See each SKU’s instructions and SDS.

ESGRAF lubricants and coatings ship from fraction-pint packs up to 5-gallon pails (and kg equivalents). Each product sheet lists SKUs and net/gross weights.

Isostatic grades offer more isotropic properties, finer grain, and higher mechanical strength for precision and EDM. Molded grades are more economical for large parts with less critical requirements.

Bars, tubes, and profiles for electrodes, resistors, bushings, and parts where extrusion-process anisotropy is acceptable or beneficial. Strong cost/performance for long lengths.

On typical geometries we hold down to ±0.02 in; tighter tolerances are reviewed by grade, size, and operation. Send a drawing or sample to confirm capability.

Synthetic, amorphous, flake, coke, and other particle sizes for foundry, pigments, muds, plastic additives, and conductive or lubricant formulations.

Yes. From drawing or sample we make graphite/carbon parts: bushings, electrodes, crucibles, seals, molds, and special components, with dimensional control and traceability.
