High-density graphite
High-density graphite for precision parts, industrial blocks, crucibles, and molds in Mexico.
Dense, machinable graphite for precision parts and industrial blocks
High-density graphite is synthetic graphite with high apparent density, controlled grain, and good machinability. It is supplied as blocks, plates, cylinders, discs, and rings, and machined to drawing when needed.
It is used for crucibles, molds (sintering, glass, jewelry, exothermic welding), dies, continuous-casting components, and parts that need dimensional stability under temperature and load. Typical density 1.78–1.90 g/cm³; grade is confirmed by application.
It is also known as isostatic, isomolded, molded, or vibration-molded graphite according to the consolidation technique.

[ FAQ ]
View all FAQsIn 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 machining tolerances (EDM, precision crucibles, critical parts).
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.
Yes. We stock industrial and high-purity isostatic graphite for EDM, precision components, molds, and vacuum or controlled-atmosphere applications.
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.
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.
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 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. Isostatic graphite provides surface finish, thermal conductivity, and dimensional stability for molds, tongs, and float-glass fenders.
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.
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.
No. They are consolidation techniques for the same high-density graphite. Grade is defined by density, grain, and application.
High-density when uniformity, fine grain, or precision machined parts are required. Extruded fits rods, tubes, heaters, and furnace parts when lower loads and anisotropy are acceptable.
Those sliding mechanical duties are usually solved with mechanical carbon-graphite (base or impregnated). High-density covers blocks and parts that prioritize density, grain, and precision machining.
