Graphite Mold

Precision Graphite Molds for Casting & Sintering

Engineered for high-accuracy continuous casting, diamond tool sintering, and glass molding, our custom graphite molds deliver superior surface finish and excellent thermal control. Machined from ultra-fine grain Graphite Blocks, these molds maintain low thermal expansion and self-lubricating characteristics that prevent sticking or deformation of cast components during cooling processes.

High Surface Machining Quality

Achieves mirror-like smoothness to ensure effortless demolding and tight end-product tolerances.

High Thermal Shock Resistance

Withstands repeated rapid temperature transitions without cracking or thermal stress fatigue.

Optional Protective Coatings

Can be enhanced via Siliconized Graphite treatment to extend mold life.
