Why KORCARB
An integrated production system means we own every step — powder formulation, pressing, sintering, grinding and coating. That is how we hold tolerance, grade consistency and lead time at once.
Capabilities
Powder, pressing, sintering, grinding and inspection on one site in Korea — no outsourced gaps.
5-axis CNC grinding holds ±2 µm on geometry, with Zoller and CMM verification on every batch.
ISO-aligned controls, RoHS-compliant materials and documented lot traceability with each shipment.
Cobalt and grain-size tuned cemented carbide grades matched to your hardness and toughness needs.
From single-drawing prototypes to repeat production runs, held in stock for fast delivery.
Supplying Korea, Japan, China, India and beyond with reliable documentation and logistics.
The Process
Tungsten and cobalt powders are formulated to the target grade.
Compacted to shape, then sintered into dense, hard blanks.
Precision-ground, coated and inspected to drawing.
